Hi.
I don't really know much in the way op5 specifics; wikipedia says it's
based on nagios.   I'd think the most reasonable path would be to look
into extending it with your own, custom monitor.   at one time I did a
couple of my own with a perl extension (which I'm not finding right now)
https://www.networkworld.com/article/2224083/how-to-extend-nagios-for-custom-monitoring.html
provides some pointers and an example of using bash, which might be helpful.

hope this is useful.
