eG Monitoring
 

Measures reported by VNXeDiskTest

This test monitors the load balancing capability of each disk of the target storage system. Using this test, administrators can pin point the disks that are handling more I/O requests than the rest. This way, irregularities in the distribution of I/O load across disks can be detected at ease and in the process, administrators would be able to fine-tune the load-balancing algorithm. In addition, the test also proactively alerts administrators to probable slowdowns in I/O processing by specific disks, thereby enabling administrators to initiate pre-emptive actions. 

Outputs of the test : One set of results for each Storage Processor: Disk combination on the target storage system being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
readBandwidth Indicates the maximum amount of data read from this disk per second. MB/sec The detailed diagnosis of this measure lists the VNX time, name of the storage processor and the read bandwidth corresponding to that time.
avgReadBandwidth Indicates the average amount of data read from this disk per second. MB/sec   
writeBandwidth Indicates the maximum amount of data written to this disk per second. MB/sec The detailed diagnosis of this measure lists the VNX time, name of the storage processor and the write bandwidth corresponding to that time.
avgWriteBandwidth Indicates the average amount of data written to this disk per second. MB/sec  
readIOPS Indicates the maximum number of read operations performed on this disk per second. IOPS The detailed diagnosis of this measure lists the VNX time, name of the storage processor and the read IOPS corresponding to that time.
avgReadIOPS Indicates the average number of read operations performed on this disk per second. IOPS  
writeIOPS Indicates the maximum number of write operations performed on this disk per second. IOPS The detailed diagnosis of this measure lists the VNX time, name of the storage processor and the write IOPS corresponding to that time.
avgWriteIOPS Indicates the average number of write operations performed on this disk per second. IOPS  
totalIOPS Indicates the total number of I/O operations performed on this disk per second. IOPS The detailed diagnosis of this measure lists the VNX time, name of the storage processor and the total IOPS corresponding to that time.
avgTotalIOPS Indicates the average number of I/O operations performed on this disk per second. IOPS  
serviceTime Indicates the maximum time taken by this disk to service user requests. Milliseconds The detailed diagnosis of this measure lists the VNX time, name of the storage processor and request service time.
avgServiceTime Indicates the average time taken by this disk to service user requests. Milliseconds  
responesTime Indicates the maximum time taken by this disk to respond to user requests. Milliseconds The detailed diagnosis of this measure lists the VNX time, name of the storage processor and the response time for user requests.
avgResponesTime Indicates the average time taken by this disk to respond to user requests. Milliseconds
