First of all, I'm a complete SNMP newbee.
My current situation: I need to monitor a LSI MegaRAID SAS 9361-8i in a Ubuntu 16.04 machine (let's call it fserv) with Zabbix. I managed to install/configure SNMP to display some information on the Zabbix server. So I'm sure snmp works in general on fserv and provides data to the Zabbix server. I have installed the lsi snmp agent on fserv but I'm not sure if it is configured right. I have modified the snmpd.conf file to pass the lsi agent.
If I enter snmpwalk -v2c -c public .220.127.116.11.4.1.3582 on the Zabbix server the answer is iso.18.104.22.168.1.3582 = No Such Instance currently exists at this OID. Same happens if I run the command with snmpwalk -v2c -c public localhost .22.214.171.124.4.1.3582 on fserv.
One thing which looks a little bit odd to me is that the lsi_mrdsnmpd service is marked as active (exited). I think it should be active but this is just a guess. My snmp config file: https://pastebin.com/1gyu95Hp
Now I'm stuck and have no clue what to do next.
