Hi all -
Not sure where to start here, so I’ll provide the facts and would appreciate someone pointing me in the right direction to troubleshoot and (hopefully) resolve this. There are a few questions here - one about capabilities, one about an actual issue I’m seeing. Thanks in advance!
First - what level of detail should I expect LibreNMS to be able to pull and provide when monitoring CUCM? CUCM is a call manager, so I would hope for/expect some details on the actual calls being managed by the system. I’ve looked through the documentation and may have missed it, but I can’t find a good “for this technology, expect these details” page so I can validate if I’m seeing what I’m supposed to.
Now for the issue - I have two CUCM systems in a cluster (virtual machines). I’ve got LibreNMS pointing at both. However I’m getting different data from the two systems, even though they are (as far as I understand) similarly configured. Specifically, on one system I’m getting health data (RAM/CPU metrics), but on the other one I’m not getting that data (the UI doesn’t even show a ‘Health’ tab for that one). This same system is also not showing storage metrics. How can I troubleshoot this effectively?
