OpenNMS Helm 5.0.0

This release fixes a number of issues, most notably compatibility with newer Grafana releases.
These fixes necessitated dropping compatibility with Grafana versions older than 6.3, so we have bumped the major version of Helm to 5.

Additionally, documentation has been improved and a number of behind-the-scenes changes have been made related to continuous integration and build system.

• HELM-64: Node search allows only to select the first 25 nodes
• HELM-196: Alarm table rendering failures with Grafana 6.5.2
• HELM-201: Panel Refreshes After Each Request When Clearing Multiple Alarms
• HELM-202: Alarms details modal shows wrong alarm when table is sorted
• HELM-208: Error appears when selecting filter type
• HELM-212: number (count) columns render wrong in Grafana 6.5 and 6.6

OpenNMS Helm 4.0.2

This release fixes a bug with the Flow datasource and Grafana 6.4, as well as some other cosmetic changes to the Flow query interface.

• HELM-190: TypeError: Cannot read property 'toBits' of undefined
• HELM-192: Rendering Bug in Flow Query Builder
• HELM-193: Conversation Flow Histogram show "null" instead of Unknown/Other in legend

OpenNMS Helm 4.0.1

This is a small revision to 4.0.0 which contains dependency updates and a fix for running under Grafana 6.4.

OpenNMS Helm 4.0.0

OpenNMS Helm 4.0 is a major update to Helm with a ***breaking*** change to datasources. Make sure you read below.

General

Helm 4 now requires Grafana 6.0 or higher.

Entities Data Source

The Fault Management Data Source is now the Entities Data Source.

In addition to querying alarms, it can now query nodes as well.
This is useful for filtering in variables, or can be used for just viewing and filtering nodes from within Grafana.

This is a breaking change that will require you to convert existing dashboards to use the new plugin.
For details on upgrading, see the Helm documentation.

Flow Data Source

• Enhancements have been made to support Horizon 25's addition of "top N" queries for conversations, hosts, and applicattions.

Filter Panel

A new panel has been added that allows you to configure a series of variables to put in a dashboard.
This panel coordinates with any panels in the dashboard using the Entities Data Source to automatically apply filters matching those variables.

In the future this will be enhanced to do more complicated set operations than are possible using the built-in datasource variables.

Alarm Table

• Alarm table code has been sync'd with enhancements from the upstream Grafana table panel.
• The new default columns and formatting for the alarm table have been updated to be more useful.
• It is now possible to configure the alarm table to not automatically refresh when new data is updated if you have navigated away from the first page of the list. When new data arrives in the background, a
  refresh icon will appear in the page bar.
• String-based columns (like log message) now get a mouseover with the full text of the column.
• Severity columns have been enhanced, including basic support for themes.
• A new column type (checkbox) has been added that will render a boolean value as either a checkmark or empty string.
• Support has been added to tag a specific alarm as the "root cause" in a situation when providing feedback in the Alarm Details screen.
• A number of UI cleanups have been made to the Alarm Details screen, fixing word wrapping, resizing when the browser is resized, and more.
• The alarm table can now export CSV and Excel files. Go to <panel title> -> More... -> Export CSV or Export Excel.

OpenNMS Helm 3.0.1

A bug fix update to Helm 3.0.0. It includes a number of changes:

• Updated a ton of dependencies, there are now 0 warnings from yarn audit (HELM-138)
• Fixes for running under Grafana 6 (HELM-132)
• A fix for parsing nested parentheses when using label formatters (HELM-131)
• Fixed relative date formatter initialization (HELM-134) (Thanks, Brynjar!)
• Includes bug fixes from OpenNMS.js v1.3.1

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

OpenNMS Helm 2.0.0

This release of OpenNMS Helm for Grafana includes a number of bug fixes and feature enhancements.

• improved error responses when queries to OpenNMS fail
• add support for displaying flow (Netflow, jFlow, sFlow, etc.) data (HELM-78)

• add support for the fallback-attribute feature in performance queries (HELM-87)
• add a "deep dive" dashboard for use with flow data (HELM-93)

OpenNMS Helm 1.1.0

This is primarily a bug fix release over Helm 1.0.0.

• update to support newer Grafana releases
• numerous build system and dependency management fixes
• fix the height of the alarm details modal to be dynamically sized (HELM-70)
