Wrapper script for ioping that can work with nagios or standalone to measure storage latency of a directory/disk/mount
Example usage:
./iomonitor --directory /tmp --min-warn 0 --min-crit 0 --max-warn 0 --max-crit 0 --avg-warn 0 --avg-crit 0 --count 15
And of course, modify warn/crit values for minimum, maximum, and average accordingly
It is suggested to first get a baseline for what your system looks like by running the script with all zeros for crit/warn then using "raw data" line to generate some values you consider warn/critical. I used a count of 120 (2 minutes) then min/max/avg * 1.5 for warning and * 2.5 for critical
You must have ioping installed. You can find it here - https://github.com/koct9i/ioping
