Measures reported by KVMStorageVolTest
This test auto discovers each storage volume of the storage pools available in the KVM server and reports the type of each storage volume and how well each volume utilizes the space allocated to it. This way, administrators are proactively alerted to potential space crunches in the storage volumes.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Type |
Indicates the type of this storage volume. |
|
The storage volume can either be Block based or File based.
The numeric values that correspond to each of the volume types discussed above are listed in the table below:
| Type |
Numeric Value |
| Block based |
0 |
| File based |
1 |
Note:
By default, this measure reports one of the Types listed in the table above. The graph of this measure however, represents the type of this storage volume using the numeric equivalents - ‘0’ to ‘1’. |
| Capacity |
Indicates the total capacity of this storage volume. |
MB |
|
| Used |
Indicates the amount of space that is already utilized in this storage volume. |
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 volume. |
MB |
A high value is desired for this measure. |
| Util |
Indicates the percentage of space that is utilized by this storage volume. |
Percent |
A very high value for this measure indicates a shortage of memory resources. If more memory is not made available soon, then this could significantly degrade the performance of the virtual machines hosted on this server.
The detailed diagnosis of this measure if enabled, lists the top 10 memory consuming processes, the PIDs of the processes and the memory utilized by each process. |
