Activate SNMP Zabbix 6.0+, Error snmp_parse_oid(): cannot parse OID

If you like me are running Ubuntu LTS 20.04+ you have to install and configure SNMP on the server as follows: 

sudo apt-get install snmp-mibs-downloader

Edit the configuration file:

sudo vi /etc/snmp/snmp.conf

Comment out mibs

Restart Zabbix

sudo systemctl restart zabbix-server

Now SNMP values should be able to be retrieved in Zabbix.

You can of course test it: 

This is a value from a temperature sensor over SNMPv2c. In this case a HWg-STE.

If it still does not work, try reaching the unit on SNMP with snmpwalk:

snmpwalk -v 2c -c supersecretcommunitystring -r 5 172.16.14.124
