v4.3.1

No manual action needed.

v4.3.0

  • StackState is tested to run on Kubernetes v1.17, v1.18 and v1.19, or the equivalent OpenShift release (version 4.4, 4.5 or 4.6).

  • CPU limits have been added to all pods. If you have customized any of the CPU requests in your values.yaml, you will most likely need to also set the CPU limit for the same pod(s).

  • CPU limits and requests have been re-evaluated and increased where needed for stable operation resulting in a change in the number and size of required nodes.

  • Two new permissions have been added - manage-event-handlers and execute-restricted-scripts:

    • Guest users will no longer be able to create or edit event handlers.

    • Power Users will no longer be able to execute scripts using the HTTP script API.

    • Admin users will not be affected.

  • Baselines have been deprecated and will be removed in v4.4. To reflect this, baseline functions and check functions that use baselines have been renamed. Templates that resolve these functions by name will stop working after upgrade to StackState 4.3. The function identifiers have not changed and can still be used to reference functions, however, it is advised that you migrate to using the Autonomous Anomaly Detector.

  • A Slack integration StackPack is now available that includes a new Slack event handler. Existing Slack event handlers will continue to run in StackState v4.3, however, the old Slack event handler has been deprecated and will be removed in a future release of StackState. To continue using Slack event notifications, it is advised to install the Slack StackPack and configure view event handlers to use the new Slack event handler in place of the old Notify via slack for component health state change. (deprecated) and Notify via slack for view health state change.(deprecated).

  • Dynatrace StackPack - The location of the Dynatrace check config file has moved. If you choose to upgrade to the version of the Dynatrace StackPack shipped with StackState v4.3, the Agent check configuration file should also be moved. The new location is /etc/sts-agent/conf.d/dynatrace.d/conf.yaml the previous location was /etc/sts-agent/conf.d/dynatrace_topology.d/conf.yaml.

Upgrade to v4.2.x

v4.2.4

No manual action needed.

v4.2.3

Authentication configuration for the Kubernetes Helm chart has been made easier for this release. If your StackState authentication was customized, it will need to be updated. To verify this, check if there is a stackstate.server.config or stackstate.api.config value that contains an authentication section in the values.yaml file(s) used for installation.

Refer to the Authentication configuration documentation to configure the same settings directly in the values.yaml file. After that, the authentication section can be completely removed. If this results in an empty config value it can be removed as well.

v4.2.0

  • Node sizing requirements have been increased.

  • The old stackstate-server pod has been replaced by a number of separate pods. Custom configuration in values.yaml should be updated:

    • Configured email details in stackstate.components.server.config should be moved to stackstate.components.viewHealth.config.

    • Other custom configuration in stackstate.components.server.config should be moved to stackstate.components.api.config.

  • A new mandatory parameter stackstate.baseUrl has been added. This is the public URL of StackState (how StackState is reachable from external machines) and is exposed via the UI script API. The file values.yaml should be updated to include the new stackstate.baseUrl parameter. The old stackstate.receiver.baseUrl parameter has been deprecated and will be removed in a future release, however, when no stackstate.baseUrl is provided in StackState v4.2, the configured stackstate.receiver.baseUrl will be used instead.

Upgrade to v4.1.0

Go to the StackState v4.1 docs site.

There are several changes to the processmanager.conf file that must be manually processed if you are using a customized version of this file:

  • The sts-healthcheckuri has been moved from port 7071 to 7080

  • The startup-check block has been removed completely

Upgrade to v4.0.0

Go to the StackState v4.0 docs site.

  • With this version the minimal system requirements for the StackState node of the production setup raised from 16GB to 20GB

  • The configuration processmanager-properties.conf was merged into processmanager.conf for both StackState and StackGraph. If you have changes to either one of those configuration files, you changes will need to be reapplied after upgrade.

  • For trace processing StackState Agent needs an upgrade to version 2.5.0.

  • This release deprecates the withCauseOf topology query filter, in favor of the `Root

    Cause Analysis` topology visualization setting. Stored views

    which require make use of the withCauseOf construct will need to be manually adapted.

    New versions of StackPacks already contain these changes, for custom views, the following

    script can be used in the StackState Analytics panel to list the views that need

    migrating.

    Graph.query { it.V().hasLabel("QueryView").forceLoadBarrier().filter(__.has("query", TextP.containing('withCauseOf'))).properties("name").value() }

  • In this release a new way of scripting propagation functions has been introduced so that the script APIs can be used. Propagation functions using the old script style will still work, but have been made read-only via the UI. Old style propagation functions can still be created via StackPacks, the CLI and API.
