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: Metric types with values of type STRING can't be retrieved by using the Cloud Monitoring 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 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.

external.googleapis.com

Metrics sent to Workspaces 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.

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 6 weeks 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.

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 Stackdriver Kubernetes Engine Monitoring, 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"
}

Note: There is presently a limit of 10,000 Prometheus-exported metric descriptors per Google Cloud project.

Other metrics

Metrics from other domains.

netapp.com

Metrics from NetApp. Launch stages of these metrics: ALPHA

The following metric type names must be prefixed with netapp.com/. That prefix has been omitted from the entries in the table.

Metric type ^Launch stage Display name
Kind, Type, Unit Monitored resources	Description Labels
cloudvolume/inode_allocation ^ALPHA Volume inode allocation
GAUGE, INT64, {inode} netapp_cloud_volume	Inode allocated for the volume (hard cap). Tied to allocated capacity (size) of volume. Sampled every 300 seconds.
cloudvolume/inode_usage ^ALPHA Volume inode usage
GAUGE, INT64, {inode} netapp_cloud_volume	Number of inode in use on the volume. Sampled every 300 seconds. type: Type of usage, either logical or snapshot.
cloudvolume/operation_count ^ALPHA Operations count
DELTA, INT64, count netapp_cloud_volume	Number of operations being performed on the cloud volume by the end users. Sampled every 60 seconds. type: Type of utilization, either logical or snapshot.
cloudvolume/read_bytes_count ^ALPHA Bytes read
DELTA, INT64, By netapp_cloud_volume	I/O bytes from read operations by the end user. Sampled every 60 seconds.
cloudvolume/request_latencies ^ALPHA Volume IO operation latency
DELTA, DISTRIBUTION, ms netapp_cloud_volume	Distribution of IO operation request latencies, in milliseconds. A measure of responsiveness of the volume. Sampled every 60 seconds. method: NetApp Cloud Volume IO operation.
cloudvolume/volume_size ^ALPHA Volume space allocation
GAUGE, INT64, By netapp_cloud_volume	Space allocated to the volume, in bytes. A measure of the actual provisioned size of the volume. Sampled every 60 seconds.
cloudvolume/volume_usage ^ALPHA Volume space usage
GAUGE, INT64, By netapp_cloud_volume	Space utilized by the volume, in bytes. A measure of the actual size of the volume. Sampled every 60 seconds. type: Type of usage, either logical or snapshot.
cloudvolume/write_bytes_count ^ALPHA Bytes written
DELTA, INT64, By netapp_cloud_volume	I/O bytes from write operations by the end user. Sampled every 60 seconds.
