Migrate for Compute Engine provides metrics for migration components via Google Cloud's operations suite. Categories of metrics include:
- Health of your Migrate for Compute Engine infrastructure
- Storage usage
- Network usage
Viewing metrics in Google Cloud's operations suite
To view the metrics for a monitored resource using Metrics Explorer, do the following:
- In the Google Cloud Console navigation pane, select Monitoring:
Go to Google Cloud ConsoleIf this is the first access of Cloud Monitoring for this Google Cloud project, then Cloud Monitoring creates a Workspace. Typically, this process is automatic and completes within a few minutes. If prompted to either select a Workspace or to create a Workspace, select create.
- In the Monitoring navigation pane, click
Metrics Explorer.
- Ensure Metric is the selected tab.
- Click in the box labeled
Find resource type and metric, and then select from the menu or
enter the name for the resource and metric. Use the following information to complete the
fields for this text box:
- For the Resource, select or enter Generic Node.
- For the Metric, select a value from the menu.
- Use the Filter, Group By, and Aggregator menus to modify how the data is displayed. If your project hosts multiple Migrate for Compute Engine Managers, you can filter by Namespace. For more information, see Selecting metrics.
Finding your namespace
- Sign in to your Migrate for Compute Engine Manager
- Click System Settings.
- Click the Logs tab.
- Your Namespace is the value after System ID on the bottom of the page.
