NMIS 9.0.0.e

This beta pre-release was published on 11 Apr 2019.
Please contact us at beta@opmantek.com if you're interested in trying out NMIS 9 pre-releases.

Highlights

  • The nmis9d (and the NMIS 9 installer) now interact cleanly with both systemd and sysv init systems.
  • Installing on Ubuntu 18 now works.
  • Orphaned worker processes left behind by a crashed nmis9d are now cleaned up more quickly and  reliably.
  • various feature extensions in admin/node_admin.pl, e.g. act=dump and act=restore can now also capture and restore a node's RRD files
  • Node deletion was  improved to ensure no scheduled collection jobs remain or interfere, and also includes historic/inactive events and operational status records.
  • Support tool no longer captures leftover legacy configuration files
  • Selftest is less likely to produce false positives
  • Node editing in the GUI now presets the configuration fields with correct defaults
  • The fping infrastructure now correctly handles the case of an admin modifying a node's IP address instead of caching stale data. 
  • Service tests whose monitoring scripts return unexpected exit codes are now  treated as 'failed/service down' and such occurrences are logged.
  • Fixed race condition in the configuration loading code, which could cause daemon crashes if the configuration is updated frequently (using the GUI or admin/patch_config.pl).
  • Various bug fixes and robustness improvements

NMIS 9.0.0d

This is a beta pre-release and was published on 21 Aug 2018.
Please contact us at beta@opmantek.com if you're interested in trying out NMIS 9 pre-releases.

Highlights

  • Feature Parity with NMIS 8.6.7G
    The improvements made in NMIS 8.6.7G have been incorporated into NMIS 9 where applicable.
  • Substantially improved GUI rendering speed and reduced resource usage
    The GUI is now usable on a system with only one CPU core and 2 GB of ram.
  • Now supports running on systems without systemd better: the installer now provides a classic init script for MongoDB
  • admin/node_admin.pl was extended to offer more flexible import and export options.
  • Various bug fixes and robustness improvements

This beta pre-release was published on 14 Jun 2018.
Please contact us at beta@opmantek.com if you're interested in trying out NMIS 9 pre-releases.

Highlights

  • Feature Parity with NMIS 8.6.6G
    NMIS 9.0.0c supports the new  Polling Failover mechanism, and all  recent improvements made in NMIS 8 are present in NMIS 9.0.0c (where applicable).
    This also includes the recent improvements for Single-Sign-On.
  • Can run in parallel with NMIS 8
    If your server specs are suitable (min. 4GB of RAM, 6-8GB recommended), then NMIS 8 and NMIS 9 can be installed on the same server without interference.
    NMIS 9 normally installs itself into /usr/local/nmis9, and its web entry point (http://localhost/nmis9/) doesn't interfere with NMIS 8.
    If the installer detects an NMIS 8 instance on your server, then it offers to import the NMIS 8 nodes' configuration: all nodes would then be polled in parallel by both NMIS 8 and NMIS 9.
  • Full installer support for platforms Debian 9, Ubuntu 16.04, CentOS 7 and 6.
  • Improved installer behaviour for both installations from scratch and upgrades from 9.0.0b.
    Upgrading from earlier releases of NMIS 9 (nightly or 9.0.0b) should now be supported seamlessly, ie. all required structural changes should be taken care of by the installer.
  • Automatic priming for monitoring of localhost, ie. the NMIS server itself
  • Node administration suite is now feature-complete
    admin/node_admin.pl can now perform all typical node operations, as well as export and import of a node's complete database information for diagnostic purposes.
  • Improved and more consistent logging
  • Fine-grained Operational Status information
    NMIS 9 now creates operational status overview records for every operation that is performed in the background.
    This operational status is accessible from the GUI (in the menu under System -> Host Diagnostics -> Ops Status).
  • Improved robustness and flexibility of the job scheduling logic
    Long-dead nodes are now demoted to fewer connection attempts after 14 days of inaccessibility.
    Job priorities can now be freely configured (see priority_schedule in conf-default/Config.nmis).
    The intial update operation for newly added nodes is now automatically prioritised above all other operations.
  • Improved self-test capability and support tool.
  • More flexibility for manually scheduled jobs
    bin/nmis-cli can now schedule any job with a specific (higher or lower than default) verbosity, which will affect just that one job.
    See the help text from bin/nmis-cli act=schedule for details.
    Furthermore, all log output for a particular job can be redirected to a separate file as well (using job.output=/some/path/nameprefix).
  • NMIS 9 CLI Improvements
    bin/nmis-cli can now show the live NMIS daemon and worker process status (with act=status).
    It is now possible to delete or abort scheduled jobs in bulk, using bin/nmis-cli act=delete-schedule id=ALL job.type=<something> job.uuid=<somenodeuuid>; note that "id=ALL" is required to indicate that all matching jobs are to be removed.
  • Various Minor GUI Improvements
    The Node dashboard widget now displays the last time  for ping, collect and update separately, and if there is a job in progress or pending for this node, then that is shown as well.

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)
