OpenNMS Helm 3.0.0

Helm 3.0 contains a large number of changes, mostly related to the Alarm Table in the Fault Management Data Source.

General

• Improved error messages for incomplete or invalid queries

Performance Data Source

• Added support for overriding time intervals and max datapoints
• Labels are now shown in the order they were queried
• Labels can now be formatted using transformation functions like
  nodeToLabel(<foreignSource:foreignId>) and resourceToName(<resourceId>)
  (Horizon 24 or greater)
• Measurements API requests are now made in relaxed mode (if the server
  is missing a particular requested attribute, all others are still returned)

Flow Data Source

• Added additional transforms for flow data (toBits, onlyIngress, onlyEgress)
• The Flow Deep Dive dashboard axis labels have been updated to be more intuitive

Fault Management Data Source

• Sorting by numeric columns now works as expected
• HTML alarm (event) log messages are now rendered properly
• Alarm multi-select and deselect now works as expected
• "Severity" in the Alarm Table panel is now a normal column, rather than a "Severity icons" check
  box in the config options -- existing configs should be automatically upgraded
• Added support for reordering columns in the Alarm Table panel
• Added support for Situations (correlated alarms), including sending feedback on
  alarm correlations (Horizon 23 or greater)
• Added limited support for multi-select dashboard variables in the Alarm Table panel
• Added a custom node attribute in the Alarm Table panel that supports node criteria
  (either passing a nodeId or foreignSource:foreignId tuple)
• Many enhancements were made to the Alarm Detail view
  (full raw response viewing, related alarms, etc.)
• It is now possible to display dates as a relative time in the Alarm Table panel
