Using metrics and running diagnostics

When troubleshooting an issue, you can work with technical support to review detailed metrics and charts for your StorageGRID system. You can also run pre-constructed diagnostic queries to proactively assess key values for your StorageGRID system.

Metrics page

The Metrics page provides access to the Prometheus and Grafana user interfaces. Prometheus is open-source software for collecting metrics. Grafana is open-source software for metrics visualization.

Attention: The tools available on the Metrics page are intended for use by technical support. Some features and menu items within these tools are intentionally non-functional and are subject to change.

The link in the Prometheus section of the Metrics page allows you to query the current values of StorageGRID metrics and to view graphs of the values over time.

Note: Metrics that include _private_ in their names are intended for internal use only and are subject to change between StorageGRID releases without notice.

The links in the Grafana section of the Metrics page allow you to access pre-constructed dashboards containing graphs of StorageGRID metrics over time.

Diagnostics page

The Diagnostics page performs a set of pre-constructed diagnostic checks on the current state of the grid. In the example, all diagnostics have a Normal status.

Clicking a specific diagnostic lets you see details about the diagnostic and its current results.

In this example, the current CPU utilization for every node in a StorageGRID system is shown. All node values are below the Attention and Caution thresholds, so the overall status of the diagnostic is Normal.
