Using Stackdriver Monitoring

Velostrata provides metrics for migration components via Stackdriver. Categories of metrics include:

  • Health of your Velostrata infrastructure
  • Storage usage
  • Network usage

Viewing metrics in Stackdriver

  1. In the Google Cloud Platform Console, select Stackdriver > Monitoring.

    Go to Monitoring

  2. Confirm that the Project hosting your Velostrata infrastructure is shown to the right of the Stackdriver logo.

  3. On the left side of the screen choose Resources > Metrics Explorer.

  4. For Resource Type, choose Generic Node.

  5. If your project hosts multiple Velostrata Managers, you can Filter by Namespace.

  6. Select a Metric from the dropdown, or copy and paste a Metric Name from the list below.

Finding your namespace

  1. Sign in to your Velostrata Manager
  2. Click System Settings.
  3. Click the Logs tab.
  4. Your Namespace is the value after System ID on the bottom of the page.

The System ID as visible from the Velostrata Manager.
