Description

Querying SNMP agents with MIB descriptions is likely to fail by default when queried via a Zabbix server SNMP agent item.

It will also fail when trying from the command line using the snmpget command,

snmpget -v2c -cmycommunity grafana.seanwasere.com IF-MIB::ifInOctets.1

--> Cannot find module (IF-MIB)
--> IF_MIB::ifInOctets.1: Unknown Object Identifier

We can enable querying by MIB descriptions by running this command on the Zabbix server itself.

sudo apt install snmp-mibs-downloader

Now this command will work

snmpwalk -v 2c -c mycommunity grafana.seanwasere.com IF-MIB::ifInOctets.1

--> IF-MIB::ifInOctets.1 = Counter32: 566637161

I then restart the Zabbix server process.

sudo service zabbix-server restart

And update my items for the host in Zabbix, to query using MIB descriptions instead of OIDs.

interface in octets ⇾ OID = IF-MIB::ifInOctets.1 (oid = 1.3.6.1.2.1.2.2.1.10.1)

interface out octets ⇾ OID = IF-MIB::ifOutOctets.1 (oid = 1.3.6.1.2.1.2.2.1.16.1)
