Rollout start: May 27, 2024
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.
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.
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.
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.
Platform | Problems
Process connection error events will now merge into the same problem when occurring on the same host.
Infrastructure Observability | Extensions
The only acceptable Content-Type for a custom Extensions 2.0 upload via REST API is application/octet-stream now.
Infrastructure Observability | ActiveGate
Unused ActiveGate module attribute KUBERNETES_AUTOMATIC_API_MONITORING
was removed from ActiveGate API response.
Infrastructure Observability | Kubernetes
Topology enrichment for Kubernetes clusters and services works correctly with defined semantic dictionary attributes:
k8s.cluster.uid
(works the same as it has already worked for dt.kubernetes.cluster.id
)k8s.service.name
(cluster and namespace have to be provided)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- getapiGroups:- dynatrace.comresources:- dynakubes
Infrastructure Observability | Kubernetes
The Monitoring mode property on the Cluster details page was renamed to Dynakube modes in the web UI.
Infrastructure Observability | Logs
You can expand wildcards in custom log sources.
builtin:logmonitoring.custom-log-source-settings
schemaIf 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
.
Infrastructure Observability | Log Monitoring
Generic log ingestion is now possible without installing Environment ActiveGate.
Infrastructure Observability
Network zones are enabled by default for new tenants created in Cluster version 1.291+.
