Kubernetes metrics

Cloud Monitoring supports the metric types from Google Kubernetes Engine listed on this page.

For a general explanation of the entries in the tables, including information about values like DELTA and GAUGE, see Metric types.

Note: Metric types with values of type STRING can't be retrieved by using the Google Cloud Console or used in alerting policies. To retrieve string-valued data, you must use a method in the Monitoring API like timeSeries.list.
For information about the units used in the metric lists, see the unit field in the MetricDescriptor reference.
For information about statements of the form “Sampled every x seconds” and “After sampling, data is not visible for up to y seconds”, see Additional information: metadata.
For a set of complete, current lists of supported metric types, see Metrics list.
For pricing information, see Monitoring pricing.

kubernetes

Metrics for Google Kubernetes Engine. Some older versions of Google Kubernetes Engine use the container metrics. For information on viewing these metrics in the Kubernetes Engine Monitoring dashboard, go to Observing your GKE clusters. Launch stages of these metrics: BETA GA

The "metric type" strings in this table must be prefixed with kubernetes.io/. That prefix has been omitted from the entries in the table.
