Monitoring storage pool utilization rates is essential to maintaining yourpooled disk resources. Compute Engine offers a high-level view of yourstorage pool metrics using theMonitoring tab in theGoogle Cloud console. This tab provides a predefined dashboard usingmetric dataso you can monitor your storage pools and make informed decisions aboutyour storage pool provisioned resources.

TheMonitoring page shows the following graphs for disk capacity, IOPS, andthroughput by default:

• Provisioned capacity, Provisioned IOPS, or Provisioned Throughput: the totalamount provisioned for the storage pool.
• Used capacity, IOPS, or throughput: Amount used by disks in the storage pool.
• Capacity Utilization, IOPS utilization, or Throughput utilization (%): thepercentage of the total used amount over the total provisioned amount.
• Total disk provisioned capacity, Total disk provisioned IOPS, and Total diskprovisioned throughput: The total provisioned capacity, IOPS, orthroughput of all disks in the storage pool.
• Capacity over-provisioning, IOPS overprovisioning, or Throughputoverprovisioning (%): the percentage of the total disk provisioned amountover the provisioned amount.

You can also customize the predefined dashboard to view only the specificmetrics that you want.

Before you begin

• If you haven't already, set upauthentication. Authentication verifies your identity for access to Google Cloud services and APIs. To run code or samples from a local development environment, you can authenticate to Compute Engine by selecting one of the following options:

  Select the tab for how you plan to use the samples on this page:

  Console

  When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

  gcloud

  1. Install the Google Cloud CLI. After installation,initialize the Google Cloud CLI by running the following command:

     gcloudinit

     If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

     Note: If you installed the gcloud CLI previously, make sure you have the latest version by runninggcloud components update.
  2. Set a default region and zone.

  REST

  To use the REST API samples on this page in a local development environment, you use the credentials you provide to the gcloud CLI.

  Install the Google Cloud CLI. After installation,initialize the Google Cloud CLI by running the following command:

  gcloudinit

  If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

  Note: If you installed the gcloud CLI previously, make sure you have the latest version by runninggcloud components update.

  For more information, seeAuthenticate for using REST in the Google Cloud authentication documentation.

Access the storage pool monitoring page

You can view the monitoring page in the Google Cloud console.

1. In the Google Cloud console, go to theStorage pools page.

   Go to Storage pools

2. Click the name of a storage pool to open theDetails page.

3. Click theMonitoring tab to display the monitoring dashboard for thestorage pool.

4. Optional: Reset the one hour default timeframe to the timeframe you wantto monitor, by choosing one of the following options:

   • 6 hours
   • 1 day
   • 1 week
   • 1 month
   • 6 weeks
   • Custom date or time range

Customize the storage pool dashboard

Use the following instructions to modify the graphs shown on thestorage pool dashboard.

1. Access the storage poolMonitoring page.

2. To change a default graph, clickquery_statsExplore data.

   This opens anExplore page, where you can create a customized monitoringchart or table. For information about how to create a chart fora specific metric, seeChart a single metric type.

3. After creating a custom graph or table, you can save the result to a new orexisting custom dashboard.
