NEMS Linux 1.5

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

Key Development Features and Goals:

  • Nagios upgraded to latest current core.
  • Adagios interface customized to remove features not part of NEMS Linux.
  • HTML email notifications.
  • Admin contacted if NEMS is offline (via API check-in).
  • NEMS NConf interface revamped to match NEMS' overall look and feel. Branding improved.
  • 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.

Release Dates:

  • The NEMS Linux 1.5 release date has not yet been announced. Because NEMS 1.4.x is rolling regular updates, I may be able to hold off 1.5 for a while since I can just update 1.4.x without the need for a re-install.

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.

NEMS 1.5

  • Coming Q4 2018.
  • Software Upgrade: Nagios Core has been upgraded from 4.3.4 to 4.4.2.
  • Software Upgrade: Check_MK livestatus socket upgraded from 1.4.0p31 to 1.4.0p37.
  • Software Upgrade: PHP upgraded from 7.0 to 7.2, introducing the Sodium cryptography library for the NEMS 1.5 Cloud Dashboard.
  • New Check Commands:
  • New Feature: NEMS 1.5 introduces NEMS Cloud Services. By signing up for this optional paid service, your NEMS Linux server will benefit from off-site backups and 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.
  • New Feature: 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.
  • New Feature: TLS Secure Authentication can be disabled in NEMS SST for SMTP email as requested by luckyworlock.
  • New Feature: nagiosgraphs now comes preinstalled as requested by Erast Fondorin.
  • New Feature: NEMS Linux now includes ConfigServer Security & Firewall (csf) with Login Failure Daemon (lfd). Internal LAN IP addresses are whitelisted by default, but if a user tries to access your NEMS server from outside the LAN (ie., if you have your NEMS server accessible on the Internet) they will get locked out if they try an incorrect password too many times.
  • Bug Fix: WiFi now works on Raspberry Pi devices out of the box.
  • Bug Fix: check_sbc_temperature (previously called check_rpi_temperature) prompts for Warning and Critical temperatures as pointed out by mgl1976.
  • Enhanced Feature: Email notifications are now responsive HTML emails. Please see the “thanks” section above.
  • Enhanced Feature: 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.
  • Miscellaneous: 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.
  • Miscellaneous: 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.
