The NEMS 1.5 release cycle will focus on an enhanced user experience and documentation.

On September 22, 2019, NEMS Linux 1.5.1 was released. It will take some time for it to be available for all platforms.

Key Development Features and Goals:

  • Nagios upgraded to latest current core.
  • HTML email notifications.
  • Admin contacted if NEMS is offline (via API check-in).
  • New plugins and check_commands integrated based on community requests.
  • Documentation at the checkcommands level improved, along with other step-by-step guides added to the documentation.
  • Bring support for industrial PCs such as the CL100 and FitLet2.
  • Create a Virtual Appliance.
  • Upgrade base to Debian Buster.
  • Upgrade PHP to 7.3.

Big thanks also to Heini Holm Andersen for granting me special permission to use, customize and distribute Nagios Responsive HTML Email Notifications Templates as part of NEMS 1.5+.

Also, thanks to Björn Ricks from Greenbone Networks for kindly providing a much more current version of WMI after OpenVAS stopped supporting it. This new version has become nems-wmic and is integrated into NEMS Linux 1.5.

Known Issues

  • While I had wanted to include a pre-configured CSF/LFD firewall with the release of NEMS Linux 1.5, unfortunately it didn't make it in on time: CSF/LFD is not yet compatible with Debian Buster, and so has been moved to NEMS Linux 1.6.
  • IMPI check commands will not function yet due to a bug in FreeIPMI. The check commands are already in place, so I will push this out as an update as soon as it is fixed upstream. Until this time, FreeIMPI and its components have been removed from NEMS Linux.

NEMS 1.5 Changelog

This changelog is a list of the major revisions culminated during this NEMS release cycle. To see the full list of Git commits, please also check out the web site.

Software Upgrades

  • Check WMI Plus upgraded to v1.64.
  • nagios-plugins 2.2.1 has been removed and replaced with the current git build of monitoring-plugins.

New Check Commands

New Features

  • NEMS Cloud Services - NEMS 1.5 introduces NEMS Cloud Services. By activating this optional service, your NEMS Linux server will benefit from off-site backups and notifications should your device stop responding (See NEMS CheckIn below). Plus, later this year I will be introducing a web-based tactical view that is accessible from anywhere, and amalgamates the tactical information of multiple NEMS servers on your account allowing sysadmins a method of monitoring multiple sites from one cloud-based dashboard.
  • NEMS CheckIn - NEMS 1.5 introduces NEMS CheckIn. CheckIn will notify you by email if your NEMS Linux server becomes unresponsive. Disabled by default, NEMS CheckIn can be configured within NEMS SST. This service requires a NEMS Cloud Services account.
  • Optional TLS - TLS Secure Authentication can be disabled in NEMS SST for SMTP email as requested by luckyworlock.
  • Graphing - nagiosgraphs now comes preinstalled as requested by Erast Fondorin. It is configured and functional in Nagios Core, but can also be accessed from the NEMS Dashboard Reporting menu.
  • Webhook Notifications - NEMS Linux now supports notifications via webhook as requested by Jon Backhaus. This feature was added to nems-tools: Warning Light.
  • Custom Appearance - NEMS SST now features the ability to change the background on some NEMS screens.
    • Background Selection, allows you to select from the following:
      • Daily Image (Default) option loads a new image every day.
      • NEMS Legacy shows the classic server room image from NEMS Linux 1.4.
      • Custom Color allows you to choose a base color to use for the background.
      • Upload Image allows you to upload your own preferred wallpaper image.
    • Blur Background Selection, allows you to add a blur effect to background images:
      • Slight Blur will add a subtle Gaussian blur to the background image.
      • Medium Blur will add a more pronounced blur to the background image.
      • Heavy Blur will blur the background image so heavily that only the color scheme of the image is recognizable.

Bug Fixes

  • WiFi now works on Raspberry Pi devices out of the box as reported by the community.
  • check_sbc_temperature (previously called check_rpi_temperature) prompts for Warning and Critical temperatures as pointed out by mgl1976.
  • Fixed Nagios Core Trends and Alert Histogram giving 404 errors as per damo.
  • Fixed Host Detail and Service detail giving 404 error as per ronjtaylor.
  • There was a known issue with Monit 5.20 (included in NEMS 1.4.1) which results in an error “Forbidden: Invalid CSRF Token”. For Monit's web interface to work, you must open it in an Incognito window (the bug is related to cookies). A fix was rolled into NEMS Linux upstream (as of October 2018). 5.25 is out in source, but not in Debian repositories. As this bug was fixed, I'm no longer concerned about the issue, though it will be nice to see 5.25 make its way into the repos.
  • DST problem in Nagvis as per ronjohntaylor fixed by system-wide timezone variables now being set in nems-init.
  • check_nrpe is now installed to the correct folder. The upstream installer places it in the folder for Nagios 3, not Nagios 4.

Improved Features

  • Email notifications are now responsive HTML emails. Please see the “thanks” section above.
  • NEMS SST now allows you to disable rolling updates. By doing so, your deployment will remain as is, allowing you to better control when/if your NEMS server is updated. As suggested by Dave Harman. Also supports putting off updates to run once per month, once per week, or once every two weeks as requested by John Naab.
  • All check_wmi_plus check commands have been redone to correct the argument counts and also to provide better descriptions for each arg. Was suggested by mydogboris.

Miscellaneous

  • samba shares have been improved to support long filenames.
  • MOTD has been improved. The generally not useful info has been removed making it a little cleaner looking, and a new ASCII logo has been integrated.
  • Removed the old default checks from NEMS host and created new templates specifically for NEMS that are more appropriate for low-powered SBCs (super high CPU load thresholds, for example). Some users were running the sample checks as if they were intended for production use rather than as a guide, so this should help those users by not setting off irrelevant alerts such as CPU load or swap usage on the NEMS server (particularly problematic on low powered devices like Raspberry Pi, since the default samples are more suited for monitoring full-powered Linux servers). Reported by experimenter, MarshMan, and others.
  • NEMS SST now warns you if you try to navigate away before saving changes.
  • WMIC is no longer being distributed by OpenVAS, so I have forked the most current git repo their parent company provided, and am now using that (after some modifications). New active repository is located at https://github.com/Cat5TV/wmic and wmic version has been upgraded from 1.3.14 to 4.0.0.
  • vim is now included by default as requested by Zerant.
  • webmin has been removed from NEMS Linux. The networking feature has been broken for quite some time, and waiting for the patches to arrive upstream has been much too long. Also, Webmin tends to confuse novice users into thinking their NEMS server is out of date (due to pending OS updates), and in some rare cases has resulted in users breaking their configuration. There are no reasons to keep Webmin, but many to remove it.
  • February 8, 2019 - Moved bootscreen to TTY7 and disabled kernel log output. TTY1 (the previous default) was also receiving syslog messages, which led to a messy screen. As noted by Bill Marshall.
  • February 9, 2019 - Raspberry Pi 2/3 Build 1 private Patron release.
  • February 9, 2019 - ODROID XU4 Build 2 private Patron release. Fixes WMIC compile issue. Updated versions of PHP, Apache2, and a few other packages that were updated upstream.
  • February 10, 2019 - Fixed ownership of nems-www, which was causing users to be unable to upload custom backgrounds. Reported by Haaku. Thanks to m9Networks and UltimateBugHunter for assisting.
  • February 10, 2019 - Fixed environment variables for local libraries to ensure wmic can find libopenvas_wmiclient.so.1. Also improved the nems-wmic installation procedure to ensure all files are saved and persistent. This to mydogboris for testing.
  • February 10, 2019 - Removed NEMS Linux version number from header of NEMS Dashboard. As it is already included in the footer, it is redundant.
  • February 10, 2019 - Removed Facebook link from NEMS Dashboard (I have been using it less and less) and changed the YouTube and Twitter links to point to the new NEMS Linux profiles, rather than my personal profiles. NEMS has its own now!
  • February 10, 2019 - ODROID XU4 Build 3 private Patron release. Merges all rolling updates. Fixes wmic.
  • February 10, 2019 - Network Manager was using its default setting to automatically spoof a new MAC address every time wifi connected. On a Raspberry Pi using WiFi, this would cause a new IP address in the DHCP pool, and users trying to establish static reservations would not be able to do so. I over-wrote the default and now the actual physical MAC address will be used. The patch will future-ready all other NEMS builds for devices that support WiFi.
  • February 10, 2019 - Raspberry Pi devices now resize the filesystem on boot, rather than on init.
  • February 10, 2019 - Raspberry Pi 2/3 Build 2 private Patron release. Merges all rolling updates. Re-compiled wmic and applied WiFi patch. Added US locale out of the box.
  • February 11, 2019 - Moved Raspberry Pi to stable kernel rather than latest kernel.
  • February 12, 2019 - ODROID XU4 Build 3 Public release.
  • February 12, 2019 - Opened ports 548,5353,5354 in CSF/LFD Firewall to allow AVAHI / mDNS to function normally, as per issue reported by Jon Backhaus. Will have no effect on NEMS Linux 1.5 since CSF/LFD are not yet compatible.
  • February 13, 2019 - Raspberry Pi 3 Model A+ added. Raspberry Pi Model B/B+ have been split so the correct board will be reported (B or B+, not B/B+).
  • February 14, 2019 - nems-update output improved. Formatting improved, and now includes the before and after git commit IDs.
  • February 14, 2019 - Fixed NEMS 1.5 using NEMS 1.4 database out of the box before initialization.
  • February 15, 2019 - Set default timezone to America/Toronto.
  • February 15, 2019 - Ensure packages are not upgraded from Sury's PHP repository on Raspberry Pi Zero/1 (breaks these builds if otherwise).
  • February 22, 2019 - Added piwatcher switch to nems-info. piWatcher support is now fully integrated and will automatically power cycle a Raspberry Pi-based NEMS Linux server if it becomes unresponsive.
  • Feburary 23, 2019 - NEMS Linux 1.5 base upgraded to Debian Buster. This resolves many backport issues on the Raspberry Pi Zero/1 build, and further upgrades many of the underlying core OS components.
  • February 23, 2019 - PHP upgraded to 7.3.
  • February 23, 2019 - CSF/LFD firewall not yet compatible with Debian Buster. Removed until such time as it is.
  • February 23, 2019 - Move JavaScript and CSS assets from CDNJS to nems-www. Users with certain DNS filters were missing components such as jQuery due to CDNJS being blocked by their DNS provider.
  • February 23, 2019 - Released Build 3 for Raspberry Pi to Patrons. This test release merges all Raspberry Pi boards into a single build and is for testing only (not for production use).
  • February 24, 2019 - Write a new installer for raspi-config on Raspberry Pi build. Build 3 failed to install it, so automated filesystem resize failed on first boot and WiFi settings could not be configured.
  • February 24, 2019 - Build 4 for Raspberry Pi released to Patrons. This is a test build that resizes correctly on first boot and supports WiFi. However it does not have the check_commands compiled so is not ready for production use.
  • February 24, 2019 - Removed nagios-plugins which appears to be a dead project (still no 2.2.2 after all these years, doesn't compile correctly on buster) and moved to monitoring-plugins which is still active and compiles nicely.
  • February 25, 2019 - Added Daily Color option to NEMS SST for background. Each day's color is extracted automatically from the color pallet of that day's daily image.
  • February 25, 2019 - Activated I2C on Raspberry Pi build to allow piWatcher compatibility. Added final timers to piWatcher script.
  • February 26, 2019 - NEMS Linux 1.5 for Raspberry Pi released to public (Build 6).
  • February 26, 2019 - nems-info ip will now output 127.0.0.1 instead of NULL if no IP address is found on a network controller. Fixes MOTD on local logins where a network connection is non-existent.
  • February 27, 2019 - Patched PHP 7.3 and PHP 7.2 configs to allow larger background image uploads in NEMS SST.
  • March 1, 2019 - NEMS Linux 1.5 Virtual Appliance OVA and VHD Build 1 released to Patrons for early testing.
  • March 2, 2019 - Connected TV screen improved to include NEMS state information. Colors softened for normal state, and will turn red in event of CRITICAL state.
  • March 2, 2019 - When uploading a custom background image, the default color is then selected from the upload and applied to the browser theme. This gives a nice consistency between uploaded image and theme colors. Note: If then changing to Custom Color, the color will be selected by default.
  • March 7, 2019 - Leaving SMTP username blank in NEMS SST now disables SMTP authentication, as requested by dr_patso on Discord (to accommodate Office 365 relay).
  • March 8, 2019 - Treat thermals as floating point instead of string in thermal logger as per nix-7.
  • March 10, 2019 - Forked monitoring-plugins and created new installer in nems-admin to fix some of the issues with the check commands.
  • March 11, 2019 - Rollout a newly compiled version of NEMS WMIC to systems who are missing it. This update takes a long time and so will lead to a new build for all platforms.
  • March 14, 2019 - Added support for MS Teams webhooks as per stealth81.
  • March 14, 2019 - Added support for Slack webhooks.
  • March 15, 2019 - Install PostgreSQL development libraries for check_psql and OpenSSL, and recompile all Nagios plugins. Fixes errors in NEMS check commands. PATCH-000001 - requires running sudo nems-upgrade
  • March 15, 2019 - Bumped check_speedtest-cli.sh to v1.3 and disabled pre-allocation of memory. This fixes “MemoryError” on lesser boards such as the Raspberry Pi Zero. New version will get installed along with PATCH-000001.
  • March 15, 2019 - Added Running/Idle status of NEMS Update and NEMS Fixes to connected TV screen.
  • March 15, 2019 - Make NEMS branding persistent in Cockpit after an update.
  • March 15, 2019 - Cleaned up some bloat in NEMS Migrator's data for NEMS 1.5 (backup copies of the MySQL database).
  • March 16, 2019 - Connected TV display now reports if the filesystem is still being resized on first boot. NEMS Quickfix now waits 90 seconds from boot to begin (in case filesystem is being resized). PATCH-000002
  • March 16, 2019 - Added glances to NEMS 1.5 as per RSABear.
  • March 16, 2019 - Switch network interface management to NetworkManager, enabling static IP configuration within the Cockpit interface. PATCH-000003
  • March 16, 2019 - Raspberry Pi Build 7 released. This introduces the new networking system to Raspberry Pi users, as well as the improved check commands and better performance on lesser boards.
  • March 21, 2019 - Added CPU temperature to connected TV display. Also fixed a math error which fixes the connected TV's ability to show if a new version of NEMS is available.
  • March 23, 2019 - PINE64 A64/A64+ Build 1 released to Patrons. In addition to everything that NEMS Linux 1.5 is, this build introduces a new kernel which addresses a known issue exists that was previously affecting <em>some</em> A64+ boards. If affected, the system clock would jump 99 years into the future&mdash;which subsequently impacted many of the NEMS services.
  • March 25, 2019 - PINE64 Rock64 Build 1 released to Patrons.
  • March 25, 2019 - If sysbench is not available, do not try to run benchmarks.
  • March 25, 2019 - Notate PATCH-000002 on Rock64 boards retroactively since the Build 1 version of the file resize script does not log the success.
  • March 25, 2019 - Added rootdev and rootpart to nems-info.
  • March 25, 2019 - New img build workflow created, including new Base Images. Theoretically img files should be a bit smaller here forward (due to zerofill) and should be more consistent (less chance for corrupt build img files).
  • March 26, 2019 - After reporting sysbench missing Buster binaries to the developer, it was added. Integrated the Buster installation into NEMS Benchmark since the Debian repositories are thus far also missing the package. System will check upstream first, and if not available, will install from developer repository.
  • March 26, 2019 - PINE64 A64/A64+ Build 1 released to public.
  • March 26, 2019 - PINE64 Rock64 Build 2 released to patrons and public. Fixes bad image creation of Build 1 causing it not to boot. Also integrates PATCH-000002.
  • March 26, 2019 - nems-quickfix (and therefore a reboot) now removes NEMS NConf generator lock file if it exists. It can get left behind in certain circumstances, which would cause NConf to say “Someone else is already generating the configuration.”
  • March 28, 2019 - PATCH-000002 now gets automatically logged to all boards if the main partition is sized greater than 9 GB. This ensures platforms such as the virtual appliance and the Rock64 transition to a ready state if the patch is not logged already but the partition is indeed resized.
  • March 28, 2019 - If sysbench is not found in the developer's repository, remove the repository and update apt before cancelling the benchmark. See Issue 298.
  • March 28, 2019 - Added speedtest to nems-info.
  • March 28, 2019 - NEMS will now automatically detect the nearest Internet speedtest server and use it by default. May be overridden by ARG if option changed in NEMS SST.
  • March 29, 2019 - Added rootfulldev to nems-info.
  • March 29, 2019 - Improved thermal detection for cross-device compatibility. Also updated nems-info temperature to output realtime thermal data rather than 15 minutes log.
  • March 29, 2019 - Added fileage to nems-info.
  • March 29, 2019 - Improved connected TV screen to now show how long updates/fixes have been running.
  • March 29, 2019 - nems-info hosts & services were showing one more than actual true count. This was due to a previous update to the livestatus socket which results in it outputting a header line, which was being counted as a result. Simply subtracted 1 to counteract. As reported by UltimateBugHunter.
  • March 29, 2019 - PINE64 A64-LTS/SOPine Build 1 patron pre-release.
  • March 30, 2019 - Retroactively enable rc.local service on boards where it is not enabled by default (eg., Rock64). Thanks to UltimateBugHunter for putting me onto the problem, having noticed the connected TV was going to sleep after 10 minutes (even though rc.local was set to disable TV sleeping).
  • March 31, 2019 - Fixed issue with temperature output on connected TV which would cause math errors when converting from Celsius to Fahrenheit.
  • March 31, 2019 - ODROID-N2 Build 1 released to patrons.
  • April 2, 2019 - NanoPi M4 Build 1 released to patrons.
  • April 2, 2019 - PINE64 A64-LTS Build 1 released to public.
  • April 4, 2019 - Change the warning message if NEMS can't connect to github, as pointed out by ITManLT.
  • April 6, 2019 - ODROID-XU4 Build 4 released. Keeping in mind the XU4 platform was the first public release of NEMS 1.5, this is a significant upgrade. This moves XU4 from Stretch to Buster and adds all the new check command scripts, as well as all updates that have been released since the first NEMS Linux 1.5 release.
  • April 7, 2019 - Virtual Appliance Build 2 (OVA, VHD, QCOW2) released to Patrons. This build was developed on an ESXi development laptop donated by bhammy187. Build 2 should be much easier to import into any hypervisor, making it significantly more portable than Build 1.
  • April 7, 2019 - Added error handling to thermal sensor check to report UNKNOWN if the sensor doesn't exist, as would be the case with a Virtual Appliance.
  • April 10, 2019 - New universal filesystem resizer automatically detects the root partition and resizes it. Will continue to adapt to eventually deprecate the separate resizer scripts for each platform.
  • April 12, 2019 - Add error handling to nems_sendmail_host and nems_sendmail_service to accommodate inability to write to Nagios log if user runs nems-mailtest as a non-root user. As reported by ITManLT.
  • April 12, 2019 - Fix issue where disabling SMTP TLS in NEMS SST would always revert to enabled. Reported by ITManLT and confirmed by UltimateBugHunter-NitPicker.
  • April 12, 2019 - ASUS Tinker Board / S Build 1 released to Patrons.
  • April 13, 2019 - ODROID-C2 Build 1 released to patrons.
  • April 15, 2019 - ODROID-N2 Build 1 and ODROID-C2 Build 1 released to public.
  • April 18, 2019 - RockPro64 Build 1 released to public.
  • April 23, 2019 - Minor verbiage adjustment re. Speedtest Server in NEMS SST.
  • April 29, 2019 - Compile sysbench if not exist, improve compatibility with various versions (ie., detect which switches are accepted for cli variables).
  • April 29, 2019 - Fix spelling of Orange Pi (DietPi had spelled it OrangePi).
  • April 30, 2019 - NEMS Linux 1.5 Build 1 for NanoPi M4 and Orange Pi Zero released to public.
  • April 30, 2019 - Update weekly benchmark to save transient data in a secure tmp folder.
  • April 30, 2019 - Re-order events in weekly benchmark to ensure the compiler runs even if a benchmark is not scheduled (so the needed software is ready to go).
  • April 30, 2019 - Lay groundwork to add 7zip benchmarks to weekly benchmark.
  • May 1, 2019 - NEMS Linux 1.5 Build 1 for NanoPi NEO Plus2 released to Patrons.
  • May 1, 2019 - Add distinction between 512 MB and 1 GB version of the NanoPi NEO Plus2.
  • May 1, 2019 - Added 7zip benchmark to weekly benchmarks.
  • May 1, 2019 - Fixed glitch in NanoPi NEO Plus2 hardware ID generator and blocked null HWID's after detecting that one Virtual Appliance user had booted a VM with no MAC address.
  • May 1, 2019 - Make weekly benchmark data readable by all, but only writable by root.
  • May 1, 2019 - Add benchmark 7z option to nems-info.
  • May 1, 2019 - Change nems-info online to use wget instead of ping. As pointed out by ITManLT, some networks block ping, causing NEMS to think it has no Internet connectivity (and therefore updates do not run).
  • May 3, 2019 - Monitorix now loads all graphs dynamically, and displays all available graphs (not just the ones I manually selected back in NEMS 1.2).
  • May 4, 2019 - Fix PHP notice for undefined variable when manually running a nems-benchmark.
  • May 4, 2019 - Finish moving nems-benchmark over to 7-Zip benchmarks rather than sysbench, and completely remove sysbench from the normal benchmark process. It will be re-added later as a supplement, but will not be used for NEMS scoring.
  • May 4, 2019 - If any of the sysbench benchmarks don't exist, output a 0 instead of a error in nems-info.
  • May 4, 2019 - Roll out a patch that removes some of the residual Armbian settings from early base images. /var/log was being loaded into zram instead of stored on disk, resulting in /var/log becoming full. This patch fixes that and ensures log files are stored on disk. Only affects early releases (such as Build 1 for TinkerBoard and NanoPi M4). Pointed out by Marshman.
  • May 8, 2019 - NEMS Linux 1.5 Build 2 for Tinker Board / S released to public.
  • May 10, 2019 - NEMS Linux 1.5 Build 2 for ODROID-N2 released, integrating Meverics' patch which resolves the networking / slowness / inability to boot issues found on some ODROID-N2 boards. Big thanks to UltimateBugHunter-NitPicker for initially reporting this issue.
  • May 16, 2019 - NEMS Linux 1.5 Virtual Appliance (OVA) Build 3 released. This build reduces the ESXi Virtual Hardware Version from 14 to 7, meaning NEMS Linux may now be deployed on older versions of ESXi. No need to re-release VMDK or QCOW2 for Build 3 since the update only affects OVA.
  • June 1, 2019 - Removed unneeded virtual hardware from OVA appliance.
  • June 2, 2019 - Restructure the Virtual Appliance OVA for compatibility with ESXi 5.5+.
  • June 3, 2019 - NEMS Linux 1.5 Virtual Appliance (OVA) Build 4 released. This build resolves the error “The OVF package is invalid and cannot be deployed” on older versions of ESXi. The cause of the issue was because older versions do not support the SHA256 hashing algorithm. Build 4 is identical to Build 3 in every way except the Cryptographic Hash Algorithm has been switched from SHA256 to SHA1, making it compatible with older ESXi servers.
  • June 13, 2019 - Upgraded speedtest from 1.0.6 to 2.1.1.
  • June 24, 2019 - Added initial Raspberry Pi 4 support.
  • June 26, 2019 - Change the way various Raspberry Pi models are displayed. Eg., Raspberry Pi 3 now, instead of previous Raspberry Pi 3 Model B. Raspberry Pi 3 B+ now instead of previous Raspberry Pi 3 Model B+.
  • June 28, 2019 - Raspberry Pi Build 8 released. Introduces out-of-the-box support for Raspberry Pi 4 and includes all patches that were issued since Build 7 was released 3 months ago.
  • June 29, 2019 - Raspberry Pi boards were previously reported as 'RPi' by the hardware description script. I didn't like this, so I changed it. Where a board previously listed itself as 'RPi 3 B+' it will now say 'Raspberry Pi 3 B+', for example.
  • June 30, 2019 - Moved monit to custom build rather than pulling from apt repository. Package is missing from some Debian Buster builds. This also ensures we have the latest version at time of build.
  • July 1, 2019 - Added new command nems-install which will install NEMS Linux on eMMC on the Khadas VIM3. In future versions, it may be expanded to support other boards if required.
  • July 1, 2019 - Khadas VIM3 Build 1 released to Patrons.
  • July 8, 2019 - Buster is now stable. Update releaseinfo, and do this automatically in future.
  • July 8, 2019 - Remove check_speedtest's reliance on a server ID. Latest version supports automatic detection on launch, and will automatically roll to next available server in line if server fails to respond. Much better than single point of failure, which has been causing false notifications the past few days. Thanks to mydogboris for reporting this.
  • July 8, 2019 - A patch to enable disabled rc.local that was previously released had been broken due to a renamed build script. Fixed.
  • July 11, 2019 - NEMS SST now features a tab “TV Dashboard”. Password setting for NEMS TV Dashboard has been moved to this tab (was previously under Optional Services), and two new features have been added: 24 hour clock formatting, ability to display faults immediately rather than waiting for the service to enter a notification state. Some users were confused by the default, so this allows them to change when they are notified.
  • July 16, 2019 - In NEMS SST, move NEMS Migrator to the NEMS Cloud Services tab.
  • July 16, 2019 - Begin encrypting NEMS State data with personal encryption/decryption password for NEMS Cloud Services users in preparation for the coming NEMS Cloud Services Dashboard.
  • July 17, 2019 - NEMS Cloud Services master NEMS Server login complete.
  • July 17, 2019 - NEMS Cloud Services now receives NEMS GPIO Extender data from subscribed devices. This will allow NEMS Warning Light or GPIO Extender Clients to be placed anywhere in the world, and will also allow a single NEMS Warning Light to display the state of multiple NEMS Servers.
  • July 18, 2019 - NEMS Cloud Services Dashboard now displays the master NEMS Server alias, CheckIn setting and Host/Service state.
  • July 19, 2019 - NEMS Cloud Services Dashboard now updates the state data automatically. This was a bit more complex than a standard ajax call due to the encrypted state of the data.
  • July 19, 2019 - Added tooltips to Host/Service icon on NEMS Cloud Services Dashboard which shows the count of each state.
  • July 19, 2019 - Added nems-info cloudauthcache option which loads the current NEMS Cloud Services authorization status from cache rather than a live connection (significantly faster for quick checks).
  • July 19, 2019 - NEMS Cloud Services Dashboard has been added to the “Reporting” menu on all NEMS servers which are connected to the service.
  • July 20, 2019 - Added NEMS Platform and Version to NEMS Cloud Services Dashboard.
  • July 22, 2019 - Added credential error handling to NEMS Cloud Services parent server login. Now, an easy to understand error message will be given if you enter invalid credentials, rather than just receiving a blank page.
  • July 25, 2019 - Moved NEMS TV Dashboards' livestatus connector to a new folder “connectors” to pave the way for new dashboard connectors.
  • July 25, 2019 - NEMS TV Dashboard has been removed from nems-www and is now its own repository called nems-tv. This is to allow me to add NEMS TV Dashboard to NEMS Cloud Services without needing to build a second (redundant) version. It also means NEMS Cloud Services' version will exactly mirror the features of the local copy.
  • July 26, 2019 - Add livestatus to nems-info.
  • July 26, 2019 - Add check to ensure nems-tv is enabled, and if not, enable it. Thanks to ITmanLT for pointing out the issue.
  • July 26, 2019 - NEMS TV Dashboard added to NEMS Cloud Services.
  • July 26, 2019 - Improve the output of the clock on NEMS TV Dashboard.
  • July 26, 2019 - Sync NEMS TV Dashboard's local clock setting to NEMS Cloud Services. Now the clock output format will match your local settings (ie., 12/24h format, whether to show am/pm).
  • July 26, 2019 - NEMS TV Dashboard in NEMS Cloud Services now shows the alias of the reporting NEMS Server. This is in preparation for the coming reconciliation of multiple connected NEMS Servers on a single NCS TV Dashboard.
  • July 29, 2019 - Added support for TEMPer hardware.
  • July 31, 2019 - Added exit codes to check_temper.
  • August 1, 2019 - Added UNKNOWN state to check_temper. If TEMPer device is disconnected, will now report UNKNOWN instead of 0°.
  • August 4, 2019 - check_temper now detects automatically whether the user is entering their ARG temperatures in C or F and acts accordingly.
  • August 12, 2019 - Major rework of NRPE. NEMS Linux no longer uses the package maintainer's version of NRPE. A new installer has also been provided for Debian hosts to ease the deployment process. Please see Check Commands: check_nrpe which details what is required.
  • August 13, 2019 - Added custom_check_mem checkcommand and corresponding NRPE advanced service, called Check Memory NRPE.
  • August 19, 2019 - Telegram notification configuration has been made more clear in NEMS SST, and the documentation has been rewritten to match.
  • August 19, 2019 - Telegram notification script reworked to remove the 'g' from Chat ID automatically, making it a bit easier to understand input.
  • August 22, 2019 - Fixed error on NEMS Cloud Services Dashboard where the tooltip() function was not loaded before it was called.
  • August 22, 2019 - Begin building a means of NEMS Cloud Services' TV Dashboard to detect and display if the NEMS Server is not online (via NEMS CheckIn). Also, the server list will now highlight down NEMS Servers red.
  • August 22, 2019 - NEMS Migrator Restore now breaks apart the checkcommands file from the NEMS backup and attempts to import each command individually. This has the effect of skipping (Aborting) import of checkcommands that already exist in the default NEMS NConf database while allowing the user-created checkcommands to be imported. Thanks to Jon Backhaus for pointing out the issue.
  • August 23, 2019 - NEMS TV Dashboard has a setting in NEMS SST that allows you to change the notifications to immediately display, rather than honoring the notifications settings in NEMS NConf. This setting now also impacts the results of nems-info state and NEMS Cloud Services' TV Dashboard.
  • August 23, 2019 - Added nems-info state all Output the state information of all NEMS hosts and services to JSON format, regardless of state.
  • August 23, 2019 - NEMS Server State Report added to NEMS Cloud Services. Now you can see the state of all your hosts/services directly from the NEMS Cloud Services Dashboard.
  • August 24, 2019 - NEMS Linux 1.5 AMI Build 1 for Amazon Web Services released.
  • September 1, 2019 - The development version of NEMS Linux for the ODROID-C1+ was losing its heartbeat following filesystem resize, so I got looking deeper at the ODROID resize stage scripts. In doing so, I found a typo in the *start* variable creation of stage1 which resulted in the first partition starting at the first sector of the disk rather than the needed sector 8192 on the ODROID-C1+. This bug has been fixed, and the ODROID-C1+ development build is working.
  • September 1, 2019 - NEMS Linux 1.5 for ODROID-C0/C1/C1+ Build 1 released.
  • September 3, 2019 - Added nems-info frequency to display the current CPU operating frequency.
  • September 5, 2019 - In nems-init the mysqld daemon is forcibly killed if stopping fails (as it tends to do on Docker). This in turn causes an error on platforms where systemd is able to stop the process: can't kill a task that isn't running. Add a check to see if mysqld is running before attempting to kill it.
  • September 5, 2019 - Push Notifications Using Telegram now includes an emoji to help distinguish the state.
  • September 5, 2019 - Improve nems-fs-resize to support drives that are not mmcblk0 type. Now, the script can be used to resize the Virtual Appliance disk, for example.
  • September 6, 2019 - Re-order the output of Telegram notifications to make them easier to see critical information at a glance. Now, the NEMS Server's alias and the timestamp are listed first, followed by the notification information.
  • September 6, 2019 - Check for the existence of rc.local before patching it in nems-update fixes. This is in particular for Docker (which doesn't use rc.local) to prevent [harmless] errors during update.
  • September 6, 2019 - Add SCSI dev assignment detection to nems-info rootfulldev/rootpart/rootdev. This fixes the feature on non-MMC storage platforms, such as the Virtual Appliance.
  • September 6, 2019 - Fixed a previously unnoticed bug in Telegram service notifications where the Service output was displaying the datestamp rather than the output.
  • September 6, 2019 - Added rich-text markdown to Telegram host and service notifications. Now, the layout looks really good (not just plain text).
  • September 6, 2019 - Added NEMS Linux Vendor Branding. Now, you can add your own logo to the NEMS Dashboard.
  • September 7, 2019 - Added the vendor logo (if applicable) to the init screen.
  • September 7, 2019 - Remove Raspberry Pi logo from boot screen.
  • September 7, 2019 - NEMS Linux 1.5 Build 2 for ODROID-C2 released.
  • September 10, 2019 - Updated migrator databases include the recommended settings for check_temper and custom_check_mem, no longer requiring users to manually add them on new deployments.
  • September 10, 2019 - Version increased to 1.5.1. No further builds of 1.5 will be created.
  • September 10, 2019 - Add nems-info perfdata_cutoff which shows the cutoff (in days) for perfdata retention.
  • September 10, 2019 - NEMS SST now has a “Maintenance” section featuring a perfdata cleanup schedule. This allows users to select to remove old perfdata to avoid a bloated perfdata.log file. As requested by rkadmin, whose file had reached 15GB in size. By default, this feature is disabled and perfdata is kept indefinitely if enabled in NEMS NConf.
  • September 10, 2019 - NEMS Cloud Services will now re-route you to the Dashboard if you have an active session. Active sessions will remain active for 24 hours. As requested by Premium.
  • September 10, 2019 - Removed the perfdata tweaks as they only bandaid the more crucial problem: a misconfigured Nagios conf. Will later add a feature to tweak nagios.cfg settings, but for now those who choose to hack their cfg files directly will probably break things.
  • September 10, 2019 - NEMS Linux 1.5.1 Build 1 for Raspberry Pi went into private testing.
  • September 13, 2019 - NEMS Cloud Services sessions now remain active for 7 days, allowing you to open NEMS Cloud Services features in your browser without needing to login (until you click Logout).
  • September 13, 2019 - nems-info frequency now reports the average frequency across all cores, rather than the frequency of the first core. Thanks to Bo from ameriDroid for pointing out this inconsistency.
  • September 13, 2019 - The build process now clears bash history correctly so on first boot, users don't have the development history.
  • September 13, 2019 - NEMS Linux 1.5.1 Build 1 for ODROID-C2 went into private testing.
  • September 19, 2019 - NEMS Migrator Off Site Backup calendar data had no error handling, so if the server didn't respond during the daily check-in, the data would still be overwritten, but with invalid JSON data. Added a JSON parser to detect if the server's response is valid JSON before clobbering the data file.
  • September 19, 2019 - Fix the name of ODROID-C2.
  • September 22, 2019 - NEMS Linux 1.5.1 for Raspberry Pi and ODROID-C2 released.
  • September 25, 2019 - NEMS Linux 1.5.1 for ODROID-XU4 released.
  • October 21, 2019 - nems-info nic and nems-info online now use nemslinux.com instead of google.com for their tests. Also, results are cached for one minute, reducing the number of requests while still remaining accurate to the minute. As requested by Joerg Hoffmann.
  • November 12, 2019 - Removed smooth scrolling from nems-www as it causes jerky behavior in modern versions of Chrome, resulting in console error, “Unable to preventDefault inside passive event listener due to target being treated as passive.”
  • November 22, 2019 - Account for the fact that some users may have passwords in their password when restoring from a NEMS Migrator backup set. Before now, a password in the password would result in a null password.
