SNMP tables

How to query elements in snmp table? For example to query interface by name?

If i use numeric OID it migth change if number of elements in table changes (for example in case of storage somebody adds new volume which is usual thing) or on some devices it changes after reboot (sometimes order of table entries changes).

I'm now puzzled how to monitor interfaces on network devices and volumes on the storage because those are all done via SNMP tables.

Load the MIB for the device onto your system. Then can query by more of name than just the OID number. Check the following link for an FAQ on SNMP:

It is all good except that zabbix stripts ."name" part of OID."name".

I found workardound - i request variable via snmpget OID."name" then get long numeric OID+OID of "name" being translated to numbers. Not very comfortable way of doing so so it would be nice if zabbix would not strip ."name" part of the variable.

sorry, but I don't really understand your workaround. Could you give me an example how you query an snmp element in a table by name?

thanks.

For example, to get the ifInOctets value for the GigabitEthernet0/1 interface on a Cisco device, use the following OID:

ifInOctets["index","ifDescr","GigabitEthernet0/1"]
