Monitoring recording via Nagios or similar

[BrusterThemand]

I'd like to automate monitoring BI to ensure that it is continuously recording and saving footage. It's happened a few times where BI just stops storing footage and I don't find out until a week or two later.

I am using LibreNMS (similar to Nagios) and would like to have it monitor BI. How would you go about this? TIA
