External metrics list

This page lists some of the metric types available from open-source projects and other external sources.

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

  Note: To chart or monitor metric types with values of type STRING, you must use Monitoring Query Language (MQL), and you must convert the value into a numeric value. For information about MQL string-conversion methods, see String.

• 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.

external.googleapis.com

Metrics sent to Google Cloud projects with a metric type beginning external.googleapis.com are known as external metrics. The metrics are typically exported by open-source projects and third-party providers. There is presently a limit of 25,000 external metric descriptors per Google Cloud project.

Cloud Monitoring treats external metrics the same as custom metrics, with one exception. For external metrics, a resource_type of global is invalid and results in the metric data being discarded.

External metric descriptors that are created but then not used for at least 24 months are subject to deletion.

Note: Until an external metric is used in a project, there is no metric descriptor for it. This is also true of custom metrics. Therefore, this page cannot list information about all the possible external metric types. If you use external metrics in your project, you can look at their metric descriptors using the metricDescriptors.list or metricDescriptors.get Monitoring API methods.

user

external.googleapis.com/user/ is a valid domain for user-defined metrics. It is functionally identical to custom.googleapis.com, although it has some backend optimizations that make queries perform better at scale. If you have many projects with identical metrics in every project, then you should use the external.googleapis.com/user/ prefix instead of custom.googleapis.com for performance reasons.

prometheus

Metrics whose names begin external.googleapis.com/prometheus/ come from Prometheus, an open-source monitoring tool often used with Kubernetes. When you configure Prometheus with Cloud Operations for GKE, metrics exported by Prometheus are converted to Cloud Monitoring metric types with simple metric descriptors, such as the following:

{
  "name": "projects/my-gcp-project/metricDescriptors/external.googleapis.com/prometheus/apiserver_client_certificate_expiration_seconds",
  "metricKind": "CUMULATIVE",
  "valueType": "DISTRIBUTION",
  "description": "Auto-created custom metric.",
  "type": "external.googleapis.com/prometheus/apiserver_client_certificate_expiration_seconds"
}

Other metrics

Metrics from other domains.
