You can monitor basic functionality of KNX components with the components you find on this site. Unfortunately, they don’t offer a script for reading KNX group addresses.
According to check_maskversion.pl, I modified the script a bit to be able to get KNX GA values: check_knx_groupaddress.pl. You can e.g. use it for checking GAs periodically for errors, e.g. some KNX devices offer GAs like “device failure”, “no signal” etc. It basically does the following:
- It runs the groupreadresponse command of the bcusdk package, which is also needed for the other KNX plugins.
- If the GA returns 0/false, the plugin returns OK -> no error. Otherwise you receive an alarm in Nagios.
You can download the Perl plugin here: check_knx_groupaddress
