NMIS 8.6.8G

This maintenance release of NMIS was published on 10 Jul 2019.

Highlights for the 8.6.8G release

• Various modelling improvements
  updates for Arista and Arris devices,  new models for Dell switches, updated and extended modelling of the Host Resources MIB (with plugin),
  adjustments for Cisco Catalyst IOSXE devices, Nexus CBQoS modelling, substantially improved modelling for Net-SNMP devices.
• The node selection, scheduling of operations and process management have been reworked extensively, and NMIS spreads the load now better and more evenly.
  • the new config options nmis_max_nodes_per_collect_cycle ,   nmis_max_nodes_per_services_cycle  and nmis_max_nodes_per_update_cycle  were added to optionally limit how many nodes should be considered at most for an operation cycle.
  • the new commandline option abort_after=N  instructs NMIS to abort unstarted collect operations for candidate nodes after N seconds (default: 60).
    Any candidate nodes that remain unhandled that long after start up are skipped (and the fact is logged), so that the next NMIS invocation can safely pick candidate nodes without overlap.
• Misbehaving Service test programs are now handled more consistently.
  All exit codes outside of the required range of 0-100 are logged and interpreted as the service being down.
• The webtest example Service test program now supports sending custom headers using -H.
• some minor GUI improvements related to node editing
• JSON event logging was extended
• NMIS' data export now includes both average and max data from rrd.
• The NMIS selftest is now less likely to produce false positives and runs faster.
• The default data retention periods for historic events has been reduced to 7 days.
• Various installer improvements, improved robustness and reduced number of repeat questions
• A new stateless event named 'Interface ifAdminStatus Changed'  is raised when an interface's administrative status changes
• The installer now handles Debian 10 (Buster), and NMIS works correctly on Debian 8 to 10.

• NMIS now supports Authentication using the host's PAM infrastructure.
• Escalation emails for failing or restored services now include the service's Description if present.
• Various other bug fixes and improvements

NMIS 8.6.7G

This is a maintenance release of NMIS, which was published on 17 Aug 2018.

Highlights for the 8.6.7G release

• The node dashboard widgets and graph drill-ins now load substantially faster,
  and graph files are now cached for up to 60 seconds (configurable via graph_file_maxage config item).
• SNMP Uptime counter wrapping (at 497 days) is now handled more robustly.
• The logic for group display/exclusion in the GUI widgets was repaired,
  and now only nodes belonging to the configured groups (in group_list) are displayed.
  (Like before, all active nodes are handled by the polling and event engine, regardless of group membership.)
• The handling of node resets and long-term unpollable nodes is now more robust and reliable.
• The Polling Failover feature was extended to provide more fine-grained events and node states.
• NMIS now provides a configurable rule for acceptable node names (using the config item node_name_rule) which is consistely applied everywhere;
  the shipped default rule was also relaxed and now allows letters, numbers, space, underscore, hyphen and dot.
• NMIS now supports WMI polling in windows domains more robustly and username and domain can be provided in multiple formats.
• Various modelling improvements, e.g. the nocollect directive is now supported in systemHealth model sections.

NMIS 8.6.7G Scaling Tip

If you are installing NMIS 8.6.7G and you have a busy server, then it is important that you modify the cron entry for NMIS and change it.

The setting is found in /etc/cron.d/nmis and the default is this:

* * * * * root /usr/local/nmis8/bin/nmis.pl type=collect mthread=true ; /usr/local/nmis8/bin/nmis.pl type=services mthread=true

This should be changed to:

*/1 * * * * root /usr/local/nmis8/bin/nmis.pl type=collect mthread=true
*/2 * * * * root /usr/local/nmis8/bin/nmis.pl type=services mthread=true

It is important to note that the NMIS polling engine had an overhaul in NMIS 8.6.6 and NMIS 8.6.7 to improve how parallel threads were handled and that polling was kept up to date.

So when NMIS starts a poll every 1 minute, not all nodes will be polled, it will poll as many as it can in that time and then leave the others for the next poll cycle, this has the result of spreading the polling (and load on the server) out over 5 minutes. If you are not getting all nodes polled in 5 minutes, you will need more threads (and enough memory).

If you are polling many nodes every 1 minute, then you will need to size the server accordingly.

NMIS 8.6.6G

This maintenance release of NMIS was published on 1 Jun 2018.

Highlights for the 8.6.6G release

• New feature for multi-homed hosts: Polling Failover.
  NMIS can now ping and (SNMP-)collect data from a node using either its (primary) host or the new host_backup address.
• The internal model cache now reacts to changes to configuration and model files automatically and immediately.
  In older versions model-related updates (e.g. threshold values) were only activated on the next type=update operation.
• Improved resiliency for Nodes.nmis
  This version of NMIS automatically removes invalid data from Nodes.nmis (e.g. caused by a faulty manual edit of the file).
  If such a problem is detected, a message with the reason of the removal is logged and written to STDERR, and the problematic record is removed completely.
• The CSV export functionality was reworked for improved robustness and convenience.
  • The  CSV file names now include the full graph heading and index/item/interface, besides the node name (as before).
  • For summarisation periods other than 'best' NMIS can now optionally add "min" and "max" columns for each data set for the relevant period.
  • The logic for summarisation period start and end now aligns the periods better with the data from the RRD files.

The latest version of NMIS can be downloaded from the Opmantek.com Download Page

NMIS 8.6.5G

This is a maintenance release of NMIS and was published on 23 May 2018.

...

• New summarisation features and improvements for CSV exporting of graph data
  CSV Exporting was made more robust, reports errors better and now produces safe comma-separated output (was tab-separated before).
  NMIS can now optionally export CSV data in summarised form (before it always returned the highest available precision data from the RRD file):
  The 'Adv. Export' page lets you choose from a number of typical summarisation periods (see config option export_summarisation_periods), or pick a custom period.
  The exported data will contain averaged values for the requested summarisation periods.
• Improved robustness for service monitoring
  Misconfigured services now show up as 'down' with an explanatory text (previously such were skipped silently). Tempfiles are not left behind anymore.
• Improved modelling for Nexus devices
• The example SNMPD configuration shipped with NMIS was adjusted for better security.
• NMIS-to-Opmantek Single-Sign-On robustness improvements
  A number of problematic corner-cases were resolved, but please note that the necessary changes are unfortunately not backwards-compatible:
  Using cookie flavour 'omk' (and appropriate secret) in NMIS 8.6.5G will only work with Opmantek application releases newer than 22.5.2018. Until at least one sufficiently new releases release is installed, OMK-NMIS cookie sharing will not work happen and separate logins will be required.

...

• The handling of nodes with large numbers of interfaces was substantially improved, and a number of optimisations to reduce the collect times for such devices were implemented.
• The event subsystem was reworked for improved performance, and a number of related bugs were identified and fixed.
• NMIS now uses locks for per-node operations to ensure correct sequencing even if an update or collect operation takes a very long time.
  Time-exceeded events now also include better diagnostic info, i.e. the node name in question.
• Improved Threshold Alerts for some measurements, e.g. CPU.
• New and improved models for Checkpoint, APC, ACME, Furukawa, Alcatel devices, Ubquiti, Microtek, Frogfoot, Cisco; better modelling of OSPF.
• A number of models have been reworked for greater modularity and ease of use. Many were adjusted to handle corner cases better.
• Updates of the Cisco product mibs.
• For newly added nodes a type=update operation is now run automatically if and when required.
• NMIS now detects problems with sending events via syslog better and logs them.
• Node Configuration overrides are now presented better in the GUI, and the nodeconf subsystem was reworked for better performance.

...

NMIS 8.5.8G

Friday 24 April 2015

...

• New and improved device support for RAD Optimux, Eltek Power UPS, net-snmp-based devices, Alcatel devices.
• Calculate and alert/threshold test and value expressions now support combining multiple variables in expressions.
• Improved CBQoS metrics

• Service testing has been streamlined, with improved graphs and the reporting of the response time for the service test.
• Service testing now supports calling external programs to test a service state.
• Improved handling of models with systemHealth sections, where all collected data is now stored in node files (and available to the GUI) instead of just when an update is run.

Fixes

• All GUI components now work in widget and standalone mode.
• Nodes that are down during updates are now correctly handled and artificial gaps in the reachability graphs are no longer created.
• Per-interface thresholds can now be disabled from the GUI.

...

• New install and upgrade script
  Simply run ./install.pl -h after unpacking NMIS to see its options.
• New Device Support
  New and improved support for GE, Zyxel and Alcatel devices, and improved support for displaying resource utilisation (cpu and memory).
• Outage Scheduler tool
  The new tool bin/schedule_outage.pl allows one to schedule future outages for groups or individual nodes.
  schedule_outage.pl sets up one-off outages only and can be run from cron to create recurring outage windows.
• Node View with configurable fields
  The new configuration option network_viewNode_field_list controls which fields  are shown in the Node View and in what order.
  The default setting  includes a standard set of properties, but custom fields are fully supported.
• Compression of rotated logs
  The configuration for log rotation was updated and streamlined,  and NMIS logs are now compressed after a week.
  install/logrotate.conf should be copied to conf in order to activate this, as well as to fix a path issue with this configuration file.
• New Global Model Overrides
  The configuration option global_collect_ifDescr was added to override the models' interface collection rules, and ifDescr was added  as a per-model collection option.
  Both of these options support regular expressions.
• More Event Details
  The new configuration option global_events_bandwidth controls whether event details should include an interface's bandwidth.

 Fixes

• Improved loading of device information for the NMIS dashboard, improving load times for large deployments
• Escalation policies now work with Event_Element fields that contain "/" characters.
• Various layout fixes for group overview and status pages, and improvements for system health display.
• The snmp maximum message size is now fully adjustable, both on a global basis as well as a per-node setting (on the Edit Node page).
• Node configuration and model editing work both as widgets and as standalone pages now.
• Unprivileged users are no longer shown menus that they are not allowed to access.
• The script subsystem for collecting service data now works as documented.
