Alert on common Kubernetes/OpenShift issues
Dynatrace version 1.254+
ActiveGate version 1.253+
To alert on common Kubernetes platform issues, follow the instructions below.
Configure
There are three ways to configure alerts for common Kubernetes/OpenShift issues.
- Settings apply to all clusters, nodes, namespaces, or workloads in the Kubernetes/OpenShift tenant.
- To configure settings, go to Settings > Anomaly detection and select any page under the Kubernetes section.
Example:
- Settings apply to a selected cluster, or to nodes, namespaces, and workloads from a selected cluster.
- To configure settings, go to the settings of a selected Kubernetes cluster and select any page under Anomaly detection.
Example:
- Settings apply to selected namespaces or workloads.
- To configure settings, go to the settings of a selected namespace and select any page under Anomaly detection.
Example:
