How to check disk I/O wait in Flowmon OS
One of the metrics that could be used to verify disk load is a percentage of I/O wait (%iowait).
Percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request.
Product: Flowmon OS
How can the disk load be analyzed?
|Steps to Reproduce:|
The percentage of I/O wait can be seen with "top" (real-time value)
or with "sar" (values reported every 10 minutes)
There is no OID representing %iowait.
The percentage of I/O wait should be below 1-2 in the long term.
