Google Cloud metrics overview (original) (raw)

Cloud Monitoring supports the metric types that Google Cloud services define. Services write metric data to record performance information. For example, a metric might record the CPU usage for a Compute Engine instance.

Each Google Cloud metric has a type, which has the formatAPI.googleapis.com/METRIC_PATH. The field API.googleapis.com specifies a service domain and it identifies the Google Cloud service or product area that owns and emits the metric. The field METRIC_PATH provides a hierarchical path that uniquely identifies the specific metric within the service domain.

The reference pages list metric types by service domain:

• Name begins with A or B
• Name begins with C
• Name begins with D through H
• Name begins with I through O
• Name begins with P through Z

For each domain, the metrics are listed alphabetically.

Find metric types

To find the metric data that is of interest to you, try the following:

• Search the API and product table.
• Issue an API request to a project.

Search the API and product table

The following table can help you find the available metric types for a service. For example, if you enter GKE in the filter bar, then the table provides links to your GKE metric types.

Issue an API request to a project

If your search terms don't match any table rows or the matched rows don't contain the data you need, then issue an API command. You can apply a filter to limit the command's response.

For example, to list metrics whose type includes disk, do the following:

1. Go to the projects.metricDescriptors.list page.
2. In the Try this method pane, do the following:
   • In the name field, enter projects/PROJECT_ID, and replacePROJECT_ID with your project ID.
   • In the filter field, enter the following:

   metric.type = has_substring("disk")  

   The hierarchical path that identifies a specific metric within a service domain uses forward slashes (/) as delimiters. You can include these delimiters in the filter. For example, the following filter matches metrics that include /disk/ in their path:

   metric.type = has_substring("/disk/")  

   There are other operators available. For example, to list all metrics whose type starts with compute, then set the filter to the following:

   metric.type = starts_with("compute")  

3. Click Execute and complete the required authorization steps.
   The command response is a list of metric descriptors whose type field matches the specified filter.

You can also issue curl commands or use client libraries to issue API commands.
