[Hyperic-hq-discuss] Need help to interpret DiskUsage data -- Unit of getServiceTime

[Rohit T. <roh...@gm...>]

Hi

I am trying to monitor my application to find which resource is limiting my
code's performance and to help me focus on areas which needs specific
optimization. Hence I want to calculate the disk utilization percentage,
for which I am using the formula - utilization = ( (read requests + write
requests) * service time in ms / 1000 ms ) * 100%.
The DiskUsage package gives the data pertaining the reads (getReads),
writes (getWrites) and service time (getServiceTime), but I am at a loss at
how interpret this data - especially the values provided by getServiceTime.
I searched the forum to find the time units of the return value of the
getServiceTime method, but could not find any information about this. I
request all of you to kindly help me, and also to please direct me if this
is a correct way to determine disk utilization.
