This is a brief overview of the major changes between opEvents releases.

opEvents 1.2.3

opEvents 1.2.3 was released on 24 Nov 2014.

  • This version includes a helper for setting up MongoDB for Opmantek use, and the installer offers to run the helper on installations and upgrades.
  • opEvents now supports per-node licensing and activation: nodes can be marked disabled from within the GUI, in which case the node does not count for license limits and no events are handled for this node. By default all nodes are active.
  • The node configuration infrastructure in opEvents is now fully unified and shared with opConfig.
  • Renaming nodes in opEvents now also renames all past events for that node.
  • opEvents now includes a full-featured command line tool for node administration, bin/opnode_admin.pl . This tool implements all node management functions already present in the GUI, as well as some extras to make it suitable for scriptable node creating and editing.
  • The ordering of rules in the event action and parsing engines was fixed (under certain circumstances rules could be tested in the wrong order in older versions).
  • The default event action rules were improved to better collect diagnostic info in reaction to node- and network-related events.
  • The event action tag.name(value) has been improved to not clash with internal properties.
  • The event action email(recip) has been revised for better standards compliance and interoperability with IP version 6.
  • opeventsd.pl now handles inadvertent log replays better. It can be told (with config option opevents_max_event_age) whether older event inputs should be processed or skipped. The handling of missing, malformatted or otherwise indigestible log files was made more robust.
  • If no opEvents license is present, then oeventsd.pl starts but doesn't consume any incoming files; it also creates a log entry about  the missing license once every 15 minutes.
  • opEvents now supports setting a custom PATH environment for running script/program event actions. If you set the config option opevents_standard_path, then opEvents will set that PATH for all external programs that it runs.
  • Opmantek applications can now be selectively enabled using the configuration option load_applications.
  • The installer for opEvents was updated to improve robustness and reliability, and opEvents now ships with the Opmantek Support Tool.
  • The display of errors and exceptions in the GUI has been improved.
  • various minor improvements and bug fixes in both the GUI as well as the back end.
  • a small warning: the installer may warn about two "incorrect checksum detected" for two files, if you install this version on top of the Opmantek Virtual Appliance version 8.5.6G or after other Opmantek applications that were released since opEvents 1.2.3. These warnings are benign and you can safely confirm that the installer is allowed to 'overwrite' those files.

opEvents 1.2.2

This is a maintenance release incorporating bug fixes and some new features:

  • opEvents now support notes for both nodes and events.
    Any notes for nodes that exist in NMIS are imported when you use Import or Refresh from NMIS (in the System->Edit Nodes menu).
    Notes for events can be edited by users with privilege Module_opEvents_rw or higher. Notes for nodes require Module_opEvents_admin.
    Both types of notes are shown on the event and node context pages and can be of arbitrary length.
  • Editing of notes for events is recorded (as an action named note) with the even, and tthe user making the change is included in the action log.
  • opEvents now creates the necessary database indices automatically on the fly, and it is no longer required to run "opeventsd.pl act=setup" for database initialization.
  • All opEvents pages were improved with regard to scalability and rendering delays have dropped substantially.
  • opEvents' Advanced Search now supports searching by node (also with regular expression).
  • The display of the event-over-time chart on the dashboard page was improved to display the  'busiest' node at the bottom of the stacking order.
  • Compatibility with Internet Explorer 11 was improved.
  • Both htpassword hashing modes (DES/Crypt and Apache-custom-MD5) are now supported.
  • some installer improvements and various minor bug fixes.

opEvents 1.2.1

This is a maintenance release which primarily incorporates bug fixes.

  • The help texts and tooltips in the GUI have been improved
  • Role-based Access Control was added to the opEvents GUI.
  • various installer improvements

opEvents 1.2.0

This is a general  release with various improvements and bug  fixes.

  • opEvents now ships with the new Opmantek Installer, which provides a much simpler and safer installation and upgrade process.
  • Restyled GUI, added glyphs for better visibility
  • A GUI for Node management was added under the System menu, which also provides access to NMIS Node Import functions.
  • New helper scripts for external event queue management were added
  • Authentication logs are now separate in log/auth.log and no longer mixed into opdaemon.log.
  • Entering a license is now simpler and requires just one click.
  • The logic and heuristic for finding associations between IP addresses, short and qualified DNS names and node names was reworked and is now much more robust.
  • Node names with "." in them work consistently now.
  • The Modules menu was reworked and is more useful now.
  • Improved opdiffconfigs, opupdateconfig and patch_config scripts are now shipped with the release.
  • The daemon init scripts now work consistently on both Debian- and Redhat-style distributions, and provice a "status" command.
  • The robustness of Quick and Advanced Search functions was improved.
  • The presentation of the Element Up/Down was repaired and improved.
  • The interoperability between Opmantek products has been greatly improved, and all products can now be installed in a cooperative fashion on the same machine.
  • The GUI now displays a prominent warning on the main dashboard page, should there be no active opevents daemon.

opEvents 1.1.2

This is a maintenance release incorporating primarily bug fixes. The two noteworthy changes:

  • A  security issue with the bundled Apache installation has been corrected, which could have been abused for denial-of-service attacks if opEvents was installed with unrestricted inbound access from the Internet.
  • The licensing system has been updated: to evaluate opEvents you will require a new evaluation license. Full licenses are not affected by this change.

opEvents 1.1.1

  • synthetic events are now subject to full deduplication and storm control
  • the package now ships with suitable default log rotation config files
  • improved robustness for log parsers and GUI behaviour
  • reworked the interface between NMIS and opevents, opeventsd now offers more precise functions for initial import and subsequent refresh operatinons of NMIS node information.
    the GUI now also provides access to these functions.
  • improved handling of stateful events for completely unknown nodes or devices
  • email contents are now completely configurable in the form of any number of user-defined templates, which includes both email subject and body.
  • the GUI now provides a link to the online product documentation.
  • opevents can now log events as JSON files, implemented as a policy action.
  • opevents now supports flexible watchdog timers for nodes and/or specific nodes' elements, implemented as policy action.

opEvents 1.1.0

  • reworked stateful deduplication and event synthesis functionality for improved robustness

opEvents 1.0.6

  • event emails were updated to contain more useful information
  • supported policy actions now also include generic tagging of an event
  • the escalation subsystem was made more resilient

  • a new generic parser engine for local customisation was added
  • opeventsd can now create events from the command-line or from a single JSON file
  • opevents now supports any number of logfiles per log parser type
