Measures reported by LHVolumeSpaceTest
A volume is a logical subdivision in a storage cluster. If a single volume in the Lefthand storage system is running out of space, it can rupture the user experience with the entire storage system. Therefore, it is necessary to monitor the space utilization of the volumes round the clock! The LHVolumeSpaceTest test helps you in this regard!
This test auto-discovers the volumes in each storage cluster and reports the space utilization of each volume. By closely monitoring the volumes, administrators can figure out whether/not any volume has been grossly over-utilized. This way, the test turns the spotlight on volumes that are experiencing potential space crunch.
Outputs of the test : One set of results for each Storage cluster:Volume combination on the target storage cluster being monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Total_size |
Indicates the total size of this volume. |
GB |
|
| Provisioned_space |
Indicates the space provisioned for this volume while created. |
GB |
|
| Used_space |
Indicates the space that was already utilized on this volume. |
GB |
A low value is desired for this measure.
Compare the value of this measure across volumes to determine the volume that is utilizing the maximum space. |
| Free_space |
Indicates the space that is available for use in this volume. |
GB |
A high value is desired for this measure. |
| Total_space_util |
Indicates the percentage of space that is utilized in this volume. |
Percent |
A high value for this measure indicates that the volume is currently running out of space. Administrators can either clear unwanted data on the volume or add additional resources. |
| Allocated_space_used |
Indicates the percentage of space already utilized from this volume against the allocated space for this volume. |
Percent |
|
| Tot_free_space_pct |
Indicates the percentage of space that is available for use in this volume. |
Percent |
A high value is desired for this measure. A value close to 0 is a cause of concern. |
| Allocated_free_pct |
Indicates the percentage of space that is available for use from this volume against the allocated space. |
Percent |
|
| Cluster_space_used |
Indicates the percentage of space utilized by this volume on the storage cluster. |
