linux snmp custom oid

[ab-tech]

Hello,
unfortunately on a server i can't install zabbix agent to monitor it, but i have only snmp agent.

my goal is monitor disk (then also a raid)
for now i would check only temperature
so i have create a script

#!/bin/bash
$(which hddtemp) -n /dev/sda

and add on /etc/snmp/snmpd.conf

extend sda_temp /bin/bash /etc/snmp/scripts/sda_temp.bash

ok now if i try to (on same server)
snmpwalk -v2c -c public localhost NET-SNMP-EXTEND-MIB::nsExtendObjects | grep sda_temp

i find my value

ok to add in zabbix i try to add items on my host (also works with cpu , memory, basic oid)

name sda temp
type snmpv2 agent
key sda.temp
snmp oid 1.3.6.1.4.1.8072.1.3.2.2.1.3.8.115.100.97.95.116.1 01.109.112.1
snmp community public
type of information numeric float
unit C
update interval (in sec) 60

but i have this error


SNMP error: (noSuchName) There is no such variable name in this MIB.

can i use this way to monitor disk temperature on snmp ?

thank you

and now works

thank you anyway

I've never been able to wrap my head around how to take the OID values retrieved with "snmpwalk" to labels that a human can understand, and I think the MIB is what provides that translation. I've never understood how to get them all working together though. I've got the MIB for my device and I've got snmpwalk working against and it returns a bunch of numerical OIDs and values. How do I figure out what all of these OIDs and their values mean?
