File Storage with Lustre Metrics
Metrics for the File Storage with Lustre service help you measure the performance, capacity, and health of a file system. You can use metrics data to diagnose and troubleshoot issues.
To view a default set of metrics charts in the Console, navigate to the file system that you're interested in, and then select Metrics. You also can use the Monitoring service to create custom queries.
You can enable logging for File Storage with Lustre resources. For more information, see Logging Overview.
Prerequisites
-
IAM policies: To monitor resources, you must be given the required type of access in a policy (IAM) written by an administrator. Policies are required for using the Console or the REST API with an SDK, CLI, or other tool. The policy must give you access to the monitoring services and the resources being monitored. When you try to perform an action, you might get a message that you don't have permission or are unauthorized. Confirm with your administrator the type of access you've been granted and which compartment you should work in. For more information on user authorizations for monitoring, see the Authentication and Authorization section for the related service: Monitoring or Notifications.
- The metrics listed on this page are automatically available for any resources you create. You don't need to enable monitoring on the resource to get these metrics.
