Query SNMP Hosts using MIBs Query SNMP Hosts using MIBs


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 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 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 =

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