Can't get SNMP to work

Dear Turris community
I’m pretty new to turris and trying to get my turris omnia ready but encountering some problems.
First I would like to install snmp on my turns to monitor the network.
I found some tutorials on how to install snmpd (net-snmpd) but I’m not able to configure the agent so I can find it in my monitoring tool. Can anybody advice me on how to setup snmp?

Best regards,
Patrick
