Dynatrace Managed release notes version 1.292

Rollout start: May 27, 2024

Announcements

Elasticsearch 8 update

This release will automatically update cluster nodes with Elasticsearch version 8.9.1 for improved performance, resilience, and security. No manual user intervention or downtime is required. The update is applied in rolling mode as part of regular version updates.

We're dropping support for IE 11

Starting with RUM JavaScript version 1.293, we will stop supporting Internet Explorer 11. For more information, see RUM JavaScript for Internet Explorer 11 and the related announcement in the Dynatrace Community.

Breaking changes

Amazon Linux 2018 is no longer supported

Amazon Linux 2018 is no longer supported. If you're running Amazon Linux 2018, you need to update your OS before you can apply this Dynatrace Managed update.

Maximum OpenTelemetry metric data points limit

Application Observability | OpenTelemetry

The OpenTelemetry protocol (OTLP) metrics ingest endpoint now enforces a maximum of 15 thousand metric data points per OTLP request. If the limit is exceeded, the endpoint returns a 413 Content Too Large response.

We recommend using a periodic metric reader in the OpenTelemetry SDK or a batch processor in the collector to limit the number of metric data points in the OTLP message.

New features and enhancements

Process connection error events

Platform | Problems

Process connection error events will now merge into the same problem when occurring on the same host.

Content-Type multipart/form-data is not supported for custom Extensions 2.0 upload

Infrastructure Observability | Extensions

The only acceptable Content-Type for a custom Extensions 2.0 upload via REST API is application/octet-stream now.

Unused ActiveGate module attribute was removed

Infrastructure Observability | ActiveGate

Unused ActiveGate module attribute KUBERNETES_AUTOMATIC_API_MONITORING was removed from ActiveGate API response.

Topology enrichment for Kubernetes clusters and services

Infrastructure Observability | Kubernetes

Topology enrichment for Kubernetes clusters and services works correctly with defined semantic dictionary attributes:

  • For cluster: k8s.cluster.uid (works the same as it has already worked for dt.kubernetes.cluster.id)
  • For service: k8s.service.name (cluster and namespace have to be provided)

Test monitoring features check for DynaKube read permission

Infrastructure Observability | Kubernetes

A check for DynaKube read permission was added for the Kubernetes cluster monitoring settings Test monitoring features button. This checks the following (optional) permission in the dynatrace-kubernetes-monitoring cluster role:

- verbs:
- list
- watch
- get
apiGroups:
- dynatrace.com
resources:
- dynakubes

"Monitoring mode" property renamed "Dynakube modes" in UI

Infrastructure Observability | Kubernetes

The Monitoring mode property on the Cluster details page was renamed to Dynakube modes in the web UI.

Wildcards in custom log sources

Infrastructure Observability | Logs

You can expand wildcards in custom log sources.

Introducing backward-incompatible changes to the builtin:logmonitoring.custom-log-source-settings schema

If you are writing the builtin:logmonitoring.custom-log-source-settings settings via API, you need to adjust them to the new schema, or specify the previous schema version, 1.0.6.

Generic log ingestion directly to cluster nodes

Infrastructure Observability | Log Monitoring

Generic log ingestion is now possible without installing Environment ActiveGate.

Network zones opt-in default

Infrastructure Observability

Network zones are enabled by default for new tenants created in Cluster version 1.291+.
