Dashboards and Splunk

The following dashboards are currently available:

Kubernetes overview
Node overview
Pod overview

Dependencies

The following are required:

Splunk version 8.0 and above. Grafana dashboards have been tested against Splunk 8.2.
Grafana version 8.2 and above.
Splunk OpenTelemetry Connector for Kubernetes - For these dashboards to be populated, Grafana requires Kubernetes data to be ingested into Splunk. Currently, the dashboards utilize metrics only from this agent. The otelK8sClusterReceiver and otelAgent daemonset are required. We recommend using the Helm chart provided by Splunk.
Splunk Open Connect - The Helm chart can be used to collect Kubernetes events. Currently, the Open Telemetry connector does not collect this data. Once added, this agent will no longer be required.

When opening a dashboard, ensure you select an appropriate metrics and events index. These default to em_metrics and main respectively.

Kubernetes overview

This dashboard provides summary statistics on the cluster concerning capacity, resource utilization and pod state. Users can filter by cluster name and namespace.
