Is there a description for the OIDs available? I ran an SNMP walk and there are hundreds of OIDs
but very few descriptions
The link below only has some descriptions, not any OIDs and not even all descriptions
It contains the object IDs, although you will need to follow the imports to get this part of them, or look it up on IANA:
enterprises is defined in the core standards and is 18.104.22.168.4.1, so 22.214.171.124.4.1.227126.96.36.199 is “Text version string of the version of Asterisk that the SNMP Agent was compiled to run against.” https://docstore.mik.ua/orelly/networking_2ndEd/snmp/ch02_03.htm
Any object ID that doesn’t being with 188.8.131.52.4.1.22736.1 is not part of Asterisk, so you will need to look for, say, the Linux MIB for details of that.
