Hi everyone. I'm getting the following error when I try to generate the snmp.yml file :-
msg="Error generating config netsnmp" err="cannot find oid 'enterprises.9.9.13.1.3.1.2' to walk"msg="Error generating config netsnmp" err="cannot find oid '.1.3.6.1.4.1.9.9.13.1.3.1.2' to walk"Here are the snmpwalk outputs :-
# snmpwalk -v3 -l authPriv -u ***** -a SHA -A ****** -x AES -X ****** XX.XX.XX.XX enterprises.9.9.13.1.3.1.2
SNMPv2-SMI::enterprises.9.9.13.1.3.1.2.1011 = STRING: "Switch 1 - Inlet Temp Sensor, GREEN "

I tried with both
enterprises.9.9.13.1.3.1.2 as well as .1.3.6.1.4.1.9.9.13.1.3.1.2 format. What changes do I need to make to generate the proper snmp.yml file? Any help is appriciated.
Thanks in advance.

Do you have the MIB file for ciscoEnvMonMIB (1.3.6.1.4.1.9.9.13) ? Is it in the right place, or pointed to by MIBDIRS environment variable? See:
In this case, the ones you need are:
auto/mibs/v2/CISCO-SMI.my # gives you enterprises.9 (cisco) and enterprises.9.9 (ciscoMgmt)
auto/mibs/v2/CISCO-ENVMON-MIB.my
Using "parse_errors" will help you find missing MIB dependencies, e.g.
MIBDIRS=+auto/mibs/v2 ./generator parse_errors
Adjust until you have no MIB parsing errors.
Then in your YML file, change
- enterprises.9.9.13.1.3.1.2
to
- ciscoEnvMonTemperatureStatusDescr
and run again.
(Note: given the other commented out OIDs you have, it's probably better just to walk the whole table, ciscoEnvMonTemperatureStatusTable)
It works for me:
$ MIBDIRS=+auto/mibs/v2 ../generator generate
level=info ts=2020-10-05T08:22:41.830Z caller=net_snmp.go:142 msg="Loading MIBs" from=$HOME/.snmp/mibs:/usr/share/snmp/mibs:/usr/share/snmp/mibs/iana:/usr/share/snmp/mibs/ietf:auto/mibs/v2

$
Aside: you may find the various public OID-searching websites helpful, e.g.
