Collected metrics and dimensions for Kubernetes

The following sections list the collected metrics when you use the default configuration for the Collector for Kubernetes in host monitoring (agent) mode.

The Collector processes collected data as configured in your pipelines. Therefore, metrics that are imported by receivers might be excluded further into the pipeline by other components. For instance, the SignalFx exporter, included in the default Collector configuration, drops certain metrics and applies translation rules that impact the metrics the Collector sends to Splunk Observability Cloud.

Learn more about the Collector’s configuration and data processing at:

• Get started with the Collector for Kubernetes

• Collector deployment modes

• Process your data with pipelines

• SignalFx exporter

Note

To see the Collector’s internal metrics, refer to Internal metrics of the Collector.

Container level metrics and dimensions

Caution

The Translated? column indicates whether the metric is translated by the SignalFx exporter.

The Exported? column indicates if the metric is finally sent to Splunk Observability Cloud after going through the Collector pipelines.
