Asterisk SNMP Monitoring

Does anyone have any Asterisk SNMP OID info? I have a found a few small references that have
both OID and description info but nothing close to a complete listing. I know the info is out there somewhere
Asterisk returns hundreds of OIDs using snmpwalk.

Any other suggestions on Asterisk monitoring ideas appreciated. There is diagnostics and stats like core show threads etc. this info should be available by OID as critical as phone systems are the lack of monitoring is really showing the immaturity of Asterisk

There is this, it hasn’t been updated since 2008.
