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 use Metrics Explorer to view the metrics for a monitored resource, follow these steps:
- In the Google Cloud console, go to the Metrics Explorer page within Monitoring.
- In the toolbar, select the Explorer tab.
- Select the Configuration tab.
- Expand the Select a metric menu, enter
Generic Nodein the filter bar, and then use the submenus to select a specific resource type and metric:- In the Active resources menu, select Generic Node.
- To select a metric, use the Active metric categories and Active metrics menus.
- Click Apply.
- Optional: To configure how the data is viewed, add filters and use the Group By, Aggregator, and chart-type menus. If your project hosts multiple Migrate for Compute Engine Managers, you can filter by Namespace. For more information, see Select metrics when using Metrics Explorer.
- Optional: Change the graph settings:
- For quota and other metrics that report one sample per day, set the time frame to at least one week and set the plot type to Stacked bar chart.
- For distribution valued metrics, set the plot type to Heatmap chart.
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.
