About the Monitor Performance App

The following information applies to version 6 (or later) of the Monitor Performance application.

Do you need to install or update the Monitor Performance app? See Manage Applications for instructions about the App Store.

Caution: If NTP is not configured, and a system in the environment transmits statistics to StorNext Connect with a time that is later than the time on the StorNext Connect server, the stats are discarded and StorNext Connect does not report accurate monitoring stats.

The Monitor Performance application allows you to monitor the performance and capacity usage of StorNext volumes (file systems). You can view performance based on specific volumes (file systems) on the Volume view / File System view or specific clients on the Client view. You can further filter the results by workspace (cluster), volume (file system), client, or time.

Note: When you monitor file systems where the metadata and data share the same LUNs, the free space remaining for either metadata or data is affected by both the metadata and data usage.
