NMIS 9.0.0b

Version 9.0.0b is a late alpha/early beta pre-release, which was published on 6 Apr 2018.
Please contact us at beta@opmantek.com if you're interested in trying out NMIS 9 pre-releases.

Highlights

  • Full installer support for platforms Debian 9, Ubuntu 16.04, CentOS 7 and 6.
  • This version can coexist with NMIS 8 on the same machine.
  • New MongoDB backend which now holds almost all node and status information.
  • Better long-term maintainability (no more configuration file or default model copying necessary)
  • New NMIS polling engine which now uses an nmis9 daemon and a configurable number of worker processes,
    which results in more even (and somewhat reduced) server resource utilisation.
  • Daemons support reconfiguration without restart for verbosity/debugging changes with signals USR1 (more verbose) and USR2 (less verbose)

Known Limitations

  • Installation on CentOS 6 takes at least 30 minutes to compile and install the necessary perl modules from CPAN
  • NMIS 9 won't work properly with less than 4GB of ram
    The polling engine does work ok with 2GB but the GUI is not optimised yet, and memory consumption will balloon very badly as soon as the GUI is accessed.
  • Upgrading from previous pre-releases (9.0.0a or nightly pre-releases) is not supported;
    We recommend that you delete both /usr/local/nmis9 and the nmisng MongoDB database before installing 9.0.0b
  • No support tool support for MongoDB yet
    The support tool doesn't yet interact with MongoDB, so won't be able to capture meaningful data for nodes in NMIS 9.
  • Report creation still relies on Cron.
  • No activity status collection and feedback for async operations yet
    All collect, update etc. operations are now asynchronous and performed by nmisd workers from a priority- and time-based queue, but support for capturing and displaying results of the operations is not completed yet. At this time only the nmis log contains that information.
    For edits from the GUI that implies that subsequent node updates cannot be observed in the GUI at this time.
  • No Documentation for nmisd and nmis-cli.pl beyond the built-in help texts.
