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

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

Hi

On going through the source code, I suspect that the service time is being
given in milli seconds. Also, I was wrong in assuming that service time
received by calling the getServiceTime function will give me the amount of
time taken to write the number of bytes between two different calls to the
disk usage object, but it tells the service time at that specific clock
tick. It would be a great addition if there was a function that could give
the difference in values between two multiple calls for  read bytes, write
bytes, service time etc.
