I’m going crazy. Checked all twice and more but I always receive this alert:

casaos@CasaOS:~$ sudo systemctl status snmp_exporter

Error parsing config file

could you help me to understand which is the problem?

Like pointed out above there seems to be a problem with your config file /etc/prometheus/snmp_exporter/snmp.yml

Try running it through a YAML verifier (you can find them online) or try posting it here (replace any passwords or sensitive info).

This morning I’ve checked and fixed the .yml file. Now I’m not able to see any data into dashboard.
I 've issued another thread about that
