Manage historical metrics values

Storage system metrics gather information about system performance and storage usage, and collect that information for user review. Analyzing the system metrics can help predict the future growth of the system.

Historical metric values are available in predefined intervals. High frequency (short interval) metric values are not kept as long as low frequency (long interval) metrics.

The following table lists the historical metrics attributes:
