snmp_exporter not able to generate the snmp.yml

[vishnu...@gmail.com]

I am trying to generate the snmp.yml file for my Juniper device on a Rocky Linux 9 system. This is the first time I am doing it on the Rocky Linux system. I copied the mibs files from the Librenms git repo to the snmp_exporter/generator/mibs/ directory. When I run make generate, it throughs me the below error. 

 make generate

make: *** [Makefile:70: generate] Error 1

I have the juniper mibs copied to the mibs folder.

# ls mibs/ | grep junos
junos
junose

also when i do ./generator generate it is looking at the /usr/share/snmp/mibs/ folder insted of the snmp_exporter/generator/mibs/ folder is there any option to include the snmp_exporter/generator/mibs/ in the lookup. 

i copied the junos mibs to /usr/share/snmp/mibs/ folder and tried running the ./generator generate command and it was giving same error. 

Some more debug

Moving the MIB files directly under the mibs folder fixed the issue. 

Previously it was kept under the mibs/junos/ folder 

Thanks,

Yes, you can set the appropriate environment variables for libsnmp.

See "man snmpcmd" for more info (at the bottom under heading "ENVIRONMENT VARIABLES"), and you will also find an example in generator/Makefile:

generate: generator mibs
        MIBDIRS=$(MIB_PATH) ./generator --fail-on-parse-errors generate
