Measures reported by KVMStoragePoolTest
A Storage pool is a logical storage group containing one or more volumes, which are virtual disks in all kinds of formats.
This test auto discovers the storage pools of the KVM server and reports the current status of each storage pool. In addition, this test provides you in detail the space utilization of each storage pool. This way, administrators are proactively alerted to potential space crunches in the storage pools of the KVM server.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| State |
Indicates the current status of this storage pool. |
|
The numeric values that correspond to each of the Measure Values that this test can take are listed in the table below:
| Measure Value |
Numeric Value |
| Unknown |
0 |
| Normal |
1 |
| Warning |
2 |
| Error |
3 |
Note:
By default, this measure reports one of the Measure Values listed in the table above. The graph of this measure however, represents the status of this storage pool using the numeric equivalents - ‘0’ to ‘3’.
|
| Capacity |
Indicates the total capacity of this storage pool. |
MB |
|
| Used |
Indicates the amount of space that is already utilized in this storage pool. |
MB |
Ideally, the value of this measure should be low. |
| Free |
Indicates the amount of space that is currently available for use in this storage pool. |
MB |
A high value is desired for this measure. |
| Util |
Indicates the percentage of space that is utilized by this storage pool. |
Percent |
A very high value for this measure indicates a space crunch in the storage pool. If adequate resources are not made availble soon, then this could significantly degrade the performance of the virtual machines that share the resources from the storage pools that are in short of adequate resources. |
