Unable to start snmp_exporter

[kommuri-bharath]

Hi Team,

I am planning to setup snmp_exporter with version 0.24.1 and found that the "auth" entry should be removed from generator.yml file in order to generate the yml. files (where I was successful). But, at the same time I am not able to start snmp_exporter service without "auth" parameter in the config files.

$ /home/snmpexp/snmp_exporter/snmp_exporter-0.24.1/snmp_exporter --config.file=/home/snmpexp/snmp_exporter/snmp_exporter-0.24.1/generator/snmp_tutti2.yml --web.listen-address=:10753

Could someone please help me on how to change the config in order to start the snmp exporter. I tried passing the auth's in snmp_tmplowner.yml file but failed.

Thanks in advance !!

The issue is because of multiple "module:" entries in snmp_tutti2.yml files. Removing the multiple entries fixed the issue.
