NMIS 9.0.6

The beta release was published on 22 August 2019.

Please contact us at beta@opmantek.com if you're interested in trying out NMIS 9 pre-releases.

Highlights

  • NMIS 9 configuration can be now set up using the master node
  • Fixed bug when renaming a node on a specific situation, when the node had track of files that doesn't exist anymore. The message was "Failed to relocate inventory storage XXX: file "/nodes/namenode/interface/inloopback0.rrd" does not exist, cannot relocate!".
  • Fixed bug in the NMIS interface that, in some situations, shows the wrong color (green) for unreachable nodes. It happened when the node was unreachable but a node down event does not exist. 
  • Fixed cgi-bin/models to handle distinction between config nmis_default_models and nmis_models directories for listing, and to use nmisng::util::getmodelfile to read the appropriate model file (custom or default); any written out data already went to the custom model directory.

  • Replace legacy logging code.
  • Fixed "Network Tools >> SNMP Tool" that was opening when the node was not active. 

NMIS 9.0.5

The beta release was published on 24 July 2019, and fixes  one scheduling bug in NMIS 9.0.4.

Highlights

  • Smarter non-interactive installation with Preseeding
  • Support to See poller nodes from the master.
  • Fixed visualisation problem with numeric node nodes. Nodes with only numbers on the name, like "12345" were causing problems on the system.
  • Show poller_event_log by default if the NMIS9 is a master, in case syslog is configured to get network events on master.
  • mojolicious 8.x is a new dependency that has a totally rotten default format for mojo::log. Fixed log format and set log_level to info which is no longer the default.
  • Fixed race condition in the poll process causing the catchall inventory data not being updating propertly when the ping operation runs at the same time. 
  • Fixed fpingd process on debian 10 was causing heaps of space padding to be added if $0 is changed.
  • Fixed NMIS9 runtime graph was not working. 
  • Change sysLocation field title to 'SNMP Location' to declash with manually configured location field, which is titled 'Location'.
  • Added hr* sections to net-snmp model so opCharts can know what charts to make. 
  • Fixed network_summary_group view had empty columns.
  • Fixed node response time graphs for nodes (shown NaN on previous):

Highlights

  • nmisng nodes now handle cluster_id on get_events_node: This is going to allow opHA to remove events from the poller on a peer deletion, so no data from the poller should remain. Also fix node_admin when dumping a node from the poller (Now will be able to get also event_data). 
  • Show message on delete node errors. 
  • Minor fixes ported from NMIS8:
    • Added support for fping inter packet gap for some firewalls. New configuration options added: fastping_interval and fastping_target_interval. 
    • IPrevent NMIS from failing when an escalation event element is c:\\
    • Adding the new opConfig "Node Configuration Change Detected event"
    • Fixed newlines being included in WMI error messages
    • Calling /proc/cpuinfo in the Support ZIP
    • run-reports.pl makes sure the reports directory exists
    • Optimisation to stop running services if no service polling required on a node
    • work around net-snmp snmpd which reports almost anything as hrfixeddisk
    • fixes for the Cisco Temperature model
  • loadServiceStatus: A new parameter is added that allows filter by all clusters. This will allow opCharts to show Monitored Services from the poller. 
  • services.nmis: Added Opmantek.pl
  • nmis-cli: On job type collect wasn't filter by local nodes.
  • purge_op_status: Changed to 7 days by default.
  • Display node name in opstatus.pl

  • Avoid pre-fill the wmiusername and wmipassword on edit/add a Node.
  • Prompt a confirmation window before deleting a node.
  • Show only local nodes. Nodes from the pollers are not shown. 
  • Fix to being able to manage a node when having another node with the same name from the poller.

Highlights

  • Lots of bug fixes, robustness and performance improvements.
  • It is no longer necessary to configure the list of groups that the NMIS GUI should show;
    by default members of all groups are visible now and only groups that are explicitely configured to be hidden (using the hide_groups  configuration item) are omitted from the display. Groups can be created and assigned freely when editing or creating nodes, both with node_admin as well as using the GUI.
  • Self-check faults are now logged as stateless events for node 'localhost' (if such a node exists).
  • NMIS 9 now supports authentication using the system's PAM authentication infrastructure.
  • NMIS 9 now properly and fully supports case-sensitivity in node names everywhere.
  • "-node" and "-info" files in var are no longer required or created.
  • Various information shown on the node dashboard is now updated immediately (e.g. "last ping" timestamp"), and no longer refreshed only during collect operations.
  • The node_admin tool now supports more complete snapshotting of nodes (with act=dump), which optionally includes the node's RRD files, events and other historic records.
    When importing a thusly dumped node with act=import it is now possible to have all identifiers localised to the current system (with localise_ids=true ); this causes the imported node to be  'adopted' by and become active on the current NMIS system immediately.
    This mechanism allows a node to be moved completely between NMIS systems, without losing any of the node's history.
  • Minor model improvements.
  • More efficient node configuration structures.
    Please note that it is necessary to run bin/nmis-cli act=noderefresh  once after upgrading to activate those changes; the installer will normally perform this operation for you.

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

...

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)
