Metric details
This topic lists the Configuration and Performance metrics collected by the Dell Compellent Enterprise Manager ETL module for entities such as storage systems, storage pools, and storage volumes.
Note
By default, extended level metrics will not be imported by the ETL.To import them, you will have to set the Collection level to [4] Extended. For more information about Aging Class Mapping, refer to the topic Metrics profile.
