The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| IO_reads |
Indicates the rate at which data was read from this device. |
KB/sec |
Compare the value of this measure to know the total number of read requests handled across disks. |
| IO_writes |
Indicates the rate at which data was written into this device. |
KB/sec |
Compare the value of this measure to know the total number of write requests handled across disks. |
| IO_read_access |
Indicates the number of times data was read from this device. |
Accesses/sec |
|
| IO_write_access |
Indicates the number of times data was written into this device. |
Accesses/sec |
|
| Disk_load |
Indicates the total percentage of space usage by disks. |
Percent |
A value close to 100% for this measure is a cause for concern, as it indicates over-utilization of disk. This can seriously degrade system performance. |
