Zabbix 4 - Monitor a specific OID

[bizzar1]

Hey to everyone!

I'm kinda new to this.
I'm trying to add one of our NAS into zabbix.
I downloaded the MiB-File, imported it into my server and successfully tested it with snmpwalk.

My problem now is, that I have some understanding issues.
I want to monitor free disk on our NAS devices.

I looked into the output from snmpwalk and tried finding something that includes something like "freedisk or anything with disk" where I can find the specific OID to add in zabbix.
I have understanding issues at this point, any help would mean alot to me.

Its not just a NAS, where i want to create an own template. In the future I want to add more specific devices and monitoring with own created templates!
Any step for step tutorial would be nice, sadly I couldn't find anything over the internet.

I appreciate any help!

TIA
