Releases

v2.3.1

Release Date: October 3rd, 2024 * [Feature] Healthwatch 2.3.1 can now receive metrics through OpenTelemetery (OTel), even if Firehose is enabled.

v2.3.0

Release Date: June 15th, 2024 * [Breaking Changes] Applicable only when using the OpenTelemetry Collector. You will notice changes in the Healthwatch metrics when you start collecting metrics using the OpenTelemetry Collector. The changes you come across are listed below:

• Metrics from the Firehose-specific components, such as reverse log proxy, are not available after enabling the OpenTelemetry Collector.
• Currently, the OpenTelemetry Collector is collocated on TAS VMs and only collects metrics from these VMs. As a result, metrics from other tiles are not collected by the OpenTelemetry Collector.
• The Prometheus exporter in the OpenTelemetry Collector does not allow leading underscore, except in private metrics. Therefore, the OpenTelemetry Collector removes any leading underscores in metric names.
• The SVM forwarder VM does not work with OpenTelemetry. You need to switch off the SVM forwarder VM if it is switched on.

• The metrics listed in the table below have the prefix grafana at the beginning of the metric name when you use the OpenTelemetery Collector.

  Metrics name with Firehose	Metric name with the OpenTelemetery Collector
  access_evaluation_duration_bucket	grafana_access_evaluation_duration_bucket
  access_evaluation_duration_count	grafana_access_evaluation_duration_count
  access_evaluation_duration_sum	grafana_access_evaluation_duration_sum
  access_permissions_duration_bucket	grafana_access_permissions_duration_bucket
  access_permissions_duration_count	grafana_access_permissions_duration_count
  access_permissions_duration_sum	grafana_access_permissions_duration_sum

• [Feature] Healthwatch 2.3.0 supports using the OpenTelemetry Collector (instead of Firehose) to collect metrics For more information, see Configure for OpenTelemetry. Once the OpenTelemetry Collector is configured, Healthwatch automatically switches to collecting metrics from the OpenTelemetery Collector. Healthwatch expects OpenTelemetry Collector data on port 65331.
