Measures reported by TPDCpgCapctyTest

A common provisioning group (CPG) creates a virtual pool of logical disks that allows virtual volumes to share the CPG's resources and allocates space on demand. A CPG allows up to 65,536 virtual volumes to share a CPG's assigned resources. The allocated capacity of CPG includes usable space, snap space and administration space. This test periodically checks the usage of those spaces on the target storage system and proactively alerts administrators to potential storage space contentions so that, amends are made before application performance deteriorates.

Outputs of the test : One set of results for the storage CPG on the storage system.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
userTotal Indicates the total user storage space of logical disks. TB  
userUsed Indicates the used storage space of logical disks. TB Ideally, this value should be low.
userFree Indicates the amount of storage space available in logical disks. TB A high value is desired for this measure. A very low value for this measure indicates a shortage of user storage space on associated logical disks.
userFreePCT Indicates the percentage of storage space available in logical disks. Percent  
snapTotal Indicates the total snap size of logical disks. TB  
snapUsed Indicates the used snap size of logical disks. TB Ideally, this value should be low.
snapFree Indicates the amount of snap size available in logical disks. TB A high value is desired for this measure. A very low value for this measure indicates a shortage of snap size on associated logical disks.
snapFreePCT Indicates the percentage of snap size available in logical disks. Percent  
adminTotal Indicates the total administration size of logical disks. TB  
adminUsed Indicates the used administration size of logical disks. TB Ideally, this value should be low.
adminFree Indicates the amount of administration size available in logical disks. TB A high value is desired for this measure. A very low value for this measure indicates a shortage of administration size on associated logical disks.
adminFreePCT Indicates the percentage of administration size available in logical disks. Percent
