check_disk_io_stats

Project Notes

This is a python rewrite of a few shell and perl versionns that I found in the exchange. I think it is simpler than the perl and more robust than the shell ones. There are ample comments in the script, but here is what it looks like when you run it with the verbose option.

[nagios@stage-ha1-db01 libexec]$ ./check_disk_io_stats --help
Usage: check_disk_io_stats [options]

Calculate disk io statistics based on /sys/block/<dev>/stat.

Options:
--version show program's version number and exit
-h, --help show this help message and exit
-d DEVICE device name listed under /sys/block
-s STATS_TYPE type of disk statistic to check, valid values are io and iops
-f STATS_FILE path to the file containing historical statistics
-w WARN warn threshold
-c CRITICAL critical threshold
-v print verbose output
