Storage performance events, incidents and thresholds
Entuity supports the inventory and status polling of the following storage assets:
- DataDomain SSH and SNMP
- Dell EMC VNX, VNXe (+Unity) NAVISecCLI and uemcli
- Dell EqualLogic SNMP
- Dell Isilon (SSH and REST API)
- HPE Nimble SSH
- NetApp SNMP (from Entuity v21.0 upwards, only NetApp SNMP is supported. Both NetApp SNMP and ssh are supported in Entuity v19.0 and v20.0.)
- Pure Storage REST
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.

Storage performance monitoring:
Entuity supports performance monitoring for the following storage devices, which draws on the data collected by Entuity's storage hardware monitoring functionality:
- DataDomain SNMP (from Entuity v20.0 P02 upwards)
- Dell EMC VNX
- Dell EMC VNXe
- Dell Isilon
- NetApp (from Entuity v20.0 P02 upwards)
- Pure Storage
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)
