It’s more the poller I’m interested in. I’d like to know if the SNMP extend request doesn’t report back correctly etc.
Currently, if I stop Asterisk, I get this in the SNMP response: “Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?)” but LibreNMS keeps the previous values for all the items you listed and so I can’t check for sipeeps = 0 or similar.
