Monitor and alert with quota metrics

Set up quota usage alerts in the Quotas page

You can set up quota alerts from the Quotas page to get notifications when your quota usage reaches a percentage of the maximum value. This feature is only supported for project-level quotas.

To set up an alert for a specific quota, do the following:

  1. Ensure you have the permission to create alerts

  2. Go to the Quotas page: Go to Quotas

  3. On the Quotas page, on the last column of the table, click the button to open the actions menu, and click Create quota alert.

  4. Select the quota usage template and select the chosen notification channels.

  5. Click Create policies

  6. Optional: If you would like to customize the default alert policy, expand the drop-down, and follow the directions.

Use Cloud Monitoring

The Cloud Monitoring API and console lets you monitor quota usage, values, and errors in greater depth. You can use these metrics to create custom dashboards and alerts.You can monitor quota usage over time and receive alerts. For example, when you're approaching a quota maximum value.

Cloud Monitoring supports a wide variety of metrics that you can combine with filters and aggregations for new and insightful views into your quota usage. For example, you can combine a metric for allocation quota usage with a quota_metric filter on Cloud TPU names.

To view the metrics for a monitored resource by using the Metrics Explorer, do the following:

  1. In the navigation panel of the Google Cloud console, select Monitoring, and then select  Metrics explorer:

    Go to Metrics explorer

  2. In the Metric element, expand the Select a metric menu, enter quota usage in the filter bar, and then use the submenus to select a specific resource type and metric:
    1. In the Active resources menu, select Consumer Quota.
    2. In the Active metric categories menu, select Quota.
    3. In the Active metrics menu, select Allocation quota usage or Rate quota usage.
    4. Click Apply.
  3. To remove time series from the display, use the Filter element.

  4. To combine time series, use the menus on the Aggregation element. For example, to display the CPU utilization for your VMs, based on their zone, set the first menu to Mean and the second menu to zone.

    All time series are displayed when the first menu of the Aggregation element is set to Unaggregated. The default settings for the Aggregation element are determined by the metric type you selected.

  5. For quota and other metrics that report one sample per day, do the following:
    1. In the Display pane, set the Widget type to Stacked bar chart.
    2. Set the time period to at least one week.

Similarly, to see quota values or exceeded errors, first select Consumer Quota as the resource type and then select Quota value or Quota exceeded error.

After you've found the quota usage information you want, you can use Cloud Monitoring to create custom dashboards and alerts to help you monitor and maintain a robust application. For more information, see the following documents:

For examples of common quota-specific alerting policies, see Using quota metrics.

The Cloud Monitoring reference guide includes a detailed reference for quota metrics.

Check quota metric support

Not all services support quota metrics in Cloud Monitoring. To see applicable quota metrics for supported services, select Consumer Quota as the resource type when building a chart or creating an alerting policy. Services that don't support quota metrics aren't displayed.

  • Common services that support quota metrics include Compute Engine, Dataflow, Spanner, Pub/Sub, Cloud Vision, Speech-to-Text, Cloud Monitoring, and Cloud Logging.

  • Common services that don't support quota metrics include App Engine and Cloud SQL.
