Measures reported by CSLDiskActivityTest

This test reports statistics pertaining to the input/output utilization of each physical disk on the control domain.

This test reports the physical CPU usage of the Oracle VM Server and points to that VM that is hogging the resources.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Percent_busy Indicates the percentage of elapsed time during which the disk is busy processing requests (i.e., reads or writes). Percent Comparing the percentage of time that the different disks are busy, an administrator can determine whether load is properly balanced across the different disks.
Disk_read_time Indicates the average time (in seconds) taken by the disk to read data. Secs Ideally, the value of this measure should be low.
Disk_write_time Indicates the average time (in seconds) taken by the disk to write data. Secs Ideally, the value of this measure should be low.
Read_rate Indicates the number of reads happening on a logical disk per second. Reads/Sec A dramatic increase in this value may be indicative of an I/O bottleneck on the control domain.
Data_read_rate Indicates the rate at which bytes are transferred from this disk during read operations. Kbytes/Sec A very high value indicates an I/O bottleneck.
Write_rate Indicates the number of writes happening on this disk per second. Writes/Sec A dramatic increase in this value may be indicative of an I/O bottleneck.
Data_write_rate Indicates the rate at which bytes are transferred from the disk during write operations. Kbytes/Sec A very high value indicates an I/O bottleneck.
Percent_disk_reads Indicates the percentage of reads happened on this disk. Percent A dramatic increase in this value may be indicative of an I/O bottleneck.
Percent_disk_writes Indicates the percentage of writes happened on this disk. Percent A very high value indicates an I/O bottleneck.
Percent_disk_writes Indicates the percentage of writes happened on this disk. Percent A very high value indicates an I/O bottleneck.
Avg_queue_length Indicates the average number of requests in the queue of this disk. Number  
Current_queue_length Indicates the current number of requests in the queue of this disk. Number
