This page discusses metrics used to monitor storage usage for zonal buckets
and cache storage usage for Rapid Cache. It also describes how to request
additional storage capacity for zonal buckets and caches beyond the default
[quotas](https://docs.cloud.google.com/storage/quotas.md.txt#rapid-cache).

For instructions on accessing monitoring data in Cloud Storage, see
[Access monitoring data](https://docs.cloud.google.com/storage/docs/access-monitoring.md.txt).

## Storage usage monitoring

Cloud Storage provides storage usage and quota monitoring for zonal buckets
that are created with [Rapid Bucket](https://docs.cloud.google.com/storage/docs/rapid/rapid-bucket.md.txt) and caches that are created with
[Rapid Cache](https://docs.cloud.google.com/storage/docs/rapid/rapid-cache.md.txt).

The following storage data is available for monitoring:

- Rapid storage bytes: monitors storage quota and usage in zonal buckets. Quota
  and usage are measured in bytes per project, per zone.

  Metric name: `storage.googleapis.com/rapid_zonal_bytes`
- Rapid Cache storage size: monitors storage quota and usage for caches
  created with Rapid Cache. Quota and usage are measured in bytes per
  project, per zone.

  Metric name: `storage.googleapis.com/anywhere_cache_storage_size`

## Request more storage for zonal buckets

The following instructions describe how to request an increase of storage
capacity for zonal buckets beyond the default quota of 1 TB.

1.


   Enable the Cloud Storage API, if it is not already enabled.


   **Roles required to enable APIs**


   To enable APIs, you need the `serviceusage.services.enable` permission. If you
   created the project, then you likely already have this permission through the
   Owner role (`roles/owner`). Otherwise, you can get this permission through the
   Service Usage Admin role (`roles/serviceusage.serviceUsageAdmin`).
   [Learn how to grant roles](https://docs.cloud.google.com/iam/docs/granting-changing-revoking-access.md.txt).

   [Enable the API](https://console.cloud.google.com/apis/enableflow?apiid=storage.googleapis.com)
2. In the Google Cloud console, go to the IAM
   **Quotas \& System Limits** page.

   [Go
   to **Quotas \& System Limits**](https://console.cloud.google.com/iam-admin/quotas)
3. In the **Filter** search bar, select the **Metric** property, then search
   for the metric `storage.googleapis.com/rapid_zonal_bytes`.

4. Identify the row for the zone in which you want to increase storage quota.
   In that row, click **More actions** ,
   then click **Edit quota**.

5. In the **Quota changes** pane that appears, enter a new quota value.

6. Click **Submit request**.

## Request more storage for Rapid Cache

To request an increase of storage capacity for Rapid Cache beyond 1 PiB,
contact your Technical Account Manager or Google representative.
