Custom MIB File Store

CMK version: 2.0.0p25 (CEE)
OS version: Ubuntu 18.04.4 LTS

Error Message
External command error: Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: iso.

Can anyone clarify where custom mib files are stored or can be uploaded to in CheckMK so they can be read when querying from check_snmp?

check_snmp -H -P 1 -o iso. -C public

This has nothing to do with the MIB file.
Your command is incorrect.
Try removing “iso” from “iso.” . If that still doesn’t work then this OID doesn’t exist on your device.


i assume that it is not a missing mib that causes the error.
Seems more like the oid or oid notation is wrong, or maybe the authentication failed and the check can´t read the oid.
Can you check with snmpget first to see if you can read the oid, maybe with the full numerical value ?

snmpget -v2c -c <Community-String> <IP-address> oid

Thank you both for your help and clarification on where I was going wrong.

I’ve ran an snmpwalk to confirm the oid and it does indeed look like I was missing a digit from the end. Silly mistake.

With the correct value and removing “oid” from the command the snmpget returns a valid value.

snmpget -v2c -c public .
iso. = INTEGER: 20

Many thanks!
