Set up quota alerts and monitoring

You can set up quota usage alerts by using the following:

Set up basic quota usage alerts

The Cloud Quotas dashboard is integrated with Cloud Monitoring. You can set up quota alerts from the Quotas & System Limits page to get notifications of quota events. For example, you can set up an alert to notify you 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 or system limit, do the following:

  1. Make sure that you have permissions to create alerts

  2. Go to the Quotas & System Limits page.

    Go to Quotas & System Limits

  3. In the right-most column of the table, click More actions, and then select Create usage alert. The Alert policy templates pane opens.

  4. Under Configure notifications, select your notification channel. The notification channel is how you receive the alert—for example email, SMS, or Pub/Sub.

  5. Click Create.

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 Google Cloud console, go to the  Metrics explorer page:

    Go to Metrics explorer

    If you use the search bar to find this page, then select the result whose subheading is Monitoring.

  2. In the toolbar of the Google Cloud console, select your Google Cloud project.
  3. 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 a metric from the list. To display both active and inactive metrics, click Active to clear the filter in the Select a metric menu.
    4. Click Apply.

  4. To remove time series from the display, use the Filter element.

  5. 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.

  6. 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.

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.
