Velostrata provides metrics for migration components via Google Cloud's operations suite. Categories of metrics include:
- Health of your Velostrata infrastructure
- Storage usage
- Network usage
Viewing metrics in Google Cloud's operations suite
In the Google Cloud Console, select Google Cloud's operations suite > Monitoring.
Confirm that the Project hosting your Velostrata infrastructure is shown to the right of the Google Cloud's operations suite logo.
On the left side of the screen choose Resources > Metrics Explorer.
For Resource Type, choose Generic Node.
If your project hosts multiple Velostrata Managers, you can Filter by Namespace.
Select a Metric from the dropdown, or copy and paste a Metric Name from the list below.
Finding your namespace
- Sign in to your Velostrata Manager
- Click System Settings.
- Click the Logs tab.
- Your Namespace is the value after System ID on the bottom of the page.
