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.

• Various minor adjustments and fixes for the NMIS graphs for better display with recent rrdtool versions

• Robustness improvements for WMI, for pinging with restrictive firewalls and for backup polling

• 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.

• New and improved devices support for Nexus 7k, Adtran, Cisco, Arista, Mikrotik, Netvanta, PulseSecure, Juniper.

• admin/node_admin.pl now supports bulk export and import..

• Various robustness improvements, e.g. in fpingd.pl, more fine-grained logging, more flexible and precise polling candidate timing decisions.

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:

This should be changed to:

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.

NMIS 8.6.5G

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

Highlights for the 8.6.5G release

• 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 release is installed, OMK-NMIS cookie sharing will not happen and separate logins will be required.

NMIS 8.6.4G

This is a maintenance release of NMIS which primarily fixes a few regressions. This release was published on 23 Mar 2018.

Highlights for the 8.6.4G release

• Users with numeric privilege level 2 and above (ie. from operator- to guest-level) were not able to login in 8.6.3G. This is now fixed.

• The newest version of the NMIS support tool is included, which collects more relevant information when investigating particular nodes.

• The Node Configuration GUI widget no longer auto-refreshes under any circumstances.

• For non-collectable but pingable nodes NMIS now defaults to model "Generic" which means a minimum of graphs can be displayed for such a node.

• For nodes that have been non-collectable for a long time NMIS now offers to attempt collect operations only once every 24 hours;
  the installer asks whether this configuration option demote_faulty_nodes should be activated or not.

• Past non-recurring Scheduled Outages are now automatically removed.

• The installer now defaults to installing all typical (but technically optional) perl modules that NMIS can use for authentication and authorization.
  Most specifically this includes Net::LDAP.

• For a number of computationally expensive operations (e.g. thresholds, metrics, escalate) NMIS now ensures that no more than one instance is running at any time.

• Various robustness improvements and minor bug fixes.

NMIS 8.6.3G

This is a maintenance release of NMIS, which does nevertheless introduce a number of new features. This release was published on 25 Jan 2018.

Highlights for the 8.6.3G release

• NMIS now supports Single Sign On with other Opmantek Applications, both for applications on a single system as well as across a whole organisation.
  The SSO section of the User Management page describes the relevant configuration options and adjustments.

• Various robustness and scalability improvements for fpingd and summary operations.
  A dead or faulty fpingd no longer causes internal pinging for all nodes, only for the ones where no or only stale fpingd data is available; fpingd is now also restarted in such cases.
  For type=summary operations NMIS now ensures that at most one such operation is running at any time.

• Robustness improvements in dealing with nodes with long-standing problems
  Nodes that have never been polled successfully are now automatically demoted to a reduced polling frequency:
  polling is attempted only once per day, and a log message about this demotion is logged (once per hour).
  Once such a node becomes pollable, polling resumes at normal frequencies.

• Polling for multiple selected groups and nodes is now possible.
  You may pass nmis.pl type=collect any number of group and node arguments, all of which will be handled inclusively;
  For example, nmis.pl type=collect group=groupA group=Bgroup node=nodeC node=nodeD will try to poll all members of the two given groups and the two given nodes (subject to polling frequency policies, of course).

• Usability improvements for the input data validation system, which now support the validation criteria 'int-or-empty' and 'float-or-empty' which accept empty inputs.
  Weird node names (ie. containing spaces or various special characters)  are now also handled more consistenly and robustly.

• Various installer improvements and updates
  If SE Linux is active, the installer now requires an explicit confirmation input to continue.
  The availability of certain packages on Debian 8, 9 and Ubuntu 16.04 is now handled more consistenly.
  The optional pre-upgrade backup now includes more relevant files, ie. cron, log rotation and apache configs.
  The permissions for log rotation files are now adjusted to appease recent versions of logrotate.

• SNMP-sourced service tests are now displayed with the time of last check.

• The NMIS GUI now masks SNMP v3 passwords and similar credentials.
  The node exception display now works better for SNMP v3 nodes.

• Improved robustness for NMIS runtime exceedence tests.
  NMIS now depends on a newer version of the Proc::ProcessTable module, which does never produce undesirable extra outputs that could create events with very weirdly named nodes (ie. lots of numbers after the node name).

• Purging of old data now optionally includes old HTML reports and JSON config log entries

• Some modelling improvements for Huawei devices

• and, as always, various minor bug fixes and improvements.

NMIS 8.6.2G

This is a major new release of NMIS which introduces a number of new features, most notably variable frequency polling, schedulable outage windows and data validation for tables.

Highlights for the 8.6.2G release

• NMIS now supports Variable Frequency Polling policies, configurable separately for each device.
  This feature can also lower the overall load substantially as not all node poll cycles need to start at the same 5 min boundary anymore.
  The minimum frequency is 60 seconds for SNMP/WMI collecting; possibly a bit lower for pinging (depending on your number of nodes).

• It is now possible to schedule recurring outage or maintenance windows with very flexible candidate and period selectors,
  and NMIS now displays outages when in effect and raises outage open/close events for external consumption.

• All NMIS tables now support configurable input data validation; this include the main system configuration.
  Additionally, numeric values for interface speeds and threshold rising/falling levels are now also enforced in the GUI.

• Audit logging
  All outage manipulations are now logged with timestamps and originator in the new audit.log logfile; this will be extended for other important activities in future versions.

• Various Model fixes, including corrected threshold-rising/falling 'Normal' level logic, repairs to model policy evaluation.

• Configurable Context Links
  NMIS now supports a per-node-configurable (and -nameable) 'Context Link' which is shown for a node's primary view.
  The node's collect and update graph is now also reachable from the Diagnostics menu in that view.

• New and improved models for Juniper, Netscreen ScreenOS, HP ProCurve, MikroTik, Alcatel, Fortinet devices, also for Cisco, Lucent and Zyxel DSLAM devices

• Installer robustness and efficiency improvements
  NMIS 8.6.2G was verified to install cleanly on CentOS 6 and 7, Debian 8 and 9 and Ubuntu LTS 16.04.1.
  On minimal installations without perl, the installer now offers to bootstrap itself by installing  the perl core first.

• and heaps of bug fixes and minor improvements

NMIS 8.6.1G

This maintainance release of NMIS was published on 21 December 2016.

Highlights for the 8.6.1G release

• new and improved device support for Juniper, Meraki, VMware ESXi, MikroTik, Alcoma, Trango, Ubquiti, Radwin Wireless and others

• Better support for devices whose SNMP agent supports snmpEngineTime.

• NMIS can now perform threshold check operations during each node's collect operation, instead of separately at the end the collect run.
  This can be controlled using the option threshold_poll_node (default: true). Performing the threshold check with the node is normally more efficient and faster.

• Disk thresholding was updated to work better with different disk sizes.

• Thresholding for WMI-sourced data now works more reliably.

• NMIS device modelling now works better with devices that have unreliable, changing object indices, and RRD database file naming can now access more variables for dynamic expansion.

• Various installer robustness improvements

• The node_admin tool now supports more fine-grained operations like act=set, and also node renaming combined with property setting in a single action.

• The Basic Setup dialog now warns about an unsafe default authentication secret key.

• NMIS now interoperates better with Nagios plugins, especially remote plugins accessed through NRPE (via the check_nrpe plugin).
  NMIS can now collect, store and display multiple 'performace values' that a Nagios plugin might return.

• Logging verbosity levels and precision were improved.

• Service checks using SAPI scripts and port connectivity checks using nmap honor timeouts now, and log more relevant information.

• various graph improvements (e.g. better legends for interface utilization and disk usage graphs),
