Hello Victor,
There are two parameters that could be measured by agent - System.CPU.Usage.IoWait and System.IO.DiskTime. What is the difference between them?
Best regards,
Roman
Hi!
System.CPU.Usage.IoWait measures how much time CPU spent waiting for I/O completion (or, more precisely, it's a percentage of time that the CPU was idle during which the system had an outstanding disk I/O request), while System.IO.DiskTime measures time disk system was busy processing requests. Not all systems can provide both parameters, and if some do, they can be very different. One example is that if you have two processes - one is I/O intensive and one is CPU intensive, your iowait % will be low, because CPU will not idling, but execute CPU intensive process while I/O intensive process waits for I/O completion.
Best regards,
Victor
Understood, thanks!
Is there documentation anywhere that details the NetXMS agent and sub-agent parameters? I'm currently trying to differentiate between System.CPU.Usage and System.CPU.LoadAvg from NetXMS Agent 1.2.3 on Windows 2008 R2 x64.
I'm sure there are many in the community who would like to have a table with specific descriptions of each NetXMS Agent parameter. Maybe it's already documented and I'm just not paying close enough attention. If anyone knows, please post a link. Thanks!
Doesn't seem to be in the wiki yet, but there's a table at the end of the old user manual:
