Entuity storage monitoring raises events when monitored storage assets are found to be in a sub-optimal state or are missing. These events contain all relevant details regarding the nature of the failure and all known inventory information about the asset.

The following Summary dashboards are available to view particular metrics:

  • Storage Summary (view level) - displays a summary of all managed storage devices.
  • Storage Device Summary
  • Storage Pool Summary
  • Volume Summary
  • LUN Summary
  • Physical Disk Summary

The hierarchy of storage performance monitoring is as follows:

  • Storage devices contain a number of physical disks.
  • Groups of physical disks are assigned to storage pools (RAID or non-RAID).
  • Each storage pool is divided into one or more volumes and LUNs (thick or thin).
  • Each LUN is exported as a single-block transfer endpoint (e.g. iSCSI target).
  • Each volume is exported by one or more shares (NFS/SMB/CIFS)
