HP 3PAR Storage CPG Capacity Test
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 storage, snap and administration spaces on each CPG in the target storage system and proactively alerts administrators if those spaces on each CPG are over-utilized.
Target of the test : A HP 3PAR Storage system
Agent deploying the test : A remote agent
Outputs of the test : One set of results for each CPG available on the target storage system.
| Parameter | Description |
|---|---|
|
Test Period |
How often should the test be executed. |
|
Host |
The IP address of the Storage system. |
|
Port |
The port number at which the Storage system listens. The default is NULL. |
|
User and Password |
By default, this test executes SSH commands on the target storage system to collect the required metrics. Specify the credentials of a user who has the right to execute SSH commands on the storage device and pull out metrics. To monitor the HP 3PAR Storage system, you will have to provide the credential of a user who has been assigned the Browse role. To know how to create a user with Browser role, refer to How to Create a New User with Browser Role? |

|
SSH Port |
The Secured Shell (SSH) port number at which the Storage system listens. The default is 22. |
|
Jar |
By default, this test uses the wbem.jar for metrics collection. This is why, the wbem option is selected by default. If you want the test to use the sblimCIMClient.jar for collecting metrics, choose the sblim option here. |
| Measurement | Description | Measurement Unit | Interpretation |
|---|---|---|---|
|
User space total |
Indicates the amount of storage space allocated to the users from this CPG. |
TB |
|
|
User space used |
Indicates the amount of storage space utilized by the users from this CPG. |
TB |
Ideally, this value should be low. |
|
User space free |
Indicates the amount of free storage space available in this CPG. |
TB |
A high value is desired for this measure. A very low value for this measure indicates a shortage of user storage space on this CPG. |
|
User space free percentage |
Indicates the percentage of free storage space available in this CPG. |
Percent |
|
|
Snap space total |
Indicates the amount of snap space allocated in this CPG. |
TB |
|
|
Snap space used |
Indicates the amount of snap space utilized from this CPG. |
TB |
Ideally, this value should be low. |
|
Snap space free |
Indicates the amount of free snap space available in this CPG. |
TB |
A high value is desired for this measure. A very low value for this measure indicates a shortage of snap space on this CPG. |
