Container metrics with CGI entity dimension

Infrastructure Observability | Kubernetes

Container metrics for the platform have been enriched with the dimension dt.entity.container_group_instance.

Fetching of Kubernetes annotations

Infrastructure Observability | Kubernetes

With ActiveGate version 1.277 and Dynatrace version 1.277, Kubernetes annotations are fetched by the ActiveGate and shown on entity detail pages for the following Kubernetes resources.

  • Services

The following limitations apply.

  • The annotation kubectl.kubernetes.io/last-applied-configuration is not ingested.

    Resolved issues

    General Availability (Build 1.277.161)

    The 1.277 GA release contains 2 resolved issue (including 1 vulnerability resolution).

    ActiveGate

    • Vulnerability: The snappy  library has been updated in response to CVE-2023-43642. (DMX-5111)
    • The builtin:kubernetes.workload.pods_desired metric has been improved to discard data points with a value of 0 that affect an environment's metric dimension limit. These data points do not affect the actual count in aggregations from the workload level to higher levels. (K8S-7774)

    Update 175 (Build 1.277.175)

    This is a cumulative update that contains all previously released updates for the 1.277 release.

    Update 177 (Build 1.277.177)

    This cumulative update contains 1 resolved issue and all previously released updates for the 1.277 release.

    ActiveGate

    • Fixed the pod dimension for the Kubernetes: Events count metric (`builtin:kubernetes.events`) provided by ActiveGate. The event count metric was mistakenly including the pod dimension. For smaller Kubernetes environments, this isn't critical. Large environments could, however, run into a metric dimension limit, which could cause monitoring gaps. (K8S-8141)

    Update 180 (Build 1.277.180)

    This is a cumulative update that contains all previously released updates for the 1.277 release.
