Debugging & Testing SNMP Issues

Install net-snmp on your system:

Mac:

brew install net-snmp

Run an SNMP simulator docker image to get a full MIB on port 161:

docker run -d -p 161:161/udp xeemetric/snmp-simulator

snmpget:

snmpget corresponds to the inputs.snmp.field configuration.

$ # get an snmp field with fully-qualified MIB name.
$ snmpget -v2c -c public localhost:161 system.sysUpTime.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (1643) 0:00:16.43

$ # get an snmp field, outputting the numeric OID.
$ snmpget -On -v2c -c public localhost:161 system.sysUpTime.0
.1.3.6.1.2.1.1.3.0 = Timeticks: (1638) 0:00:16.38

snmptranslate:

snmptranslate can be used to translate an OID to a MIB name:

$ snmptranslate .1.3.6.1.2.1.1.3.0
DISMAN-EVENT-MIB::sysUpTimeInstance

And to convert a partial MIB name to a fully qualified one:

$ snmptranslate -IR sysUpTime.0
DISMAN-EVENT-MIB::sysUpTimeInstance

And to convert a MIB name to an OID:

$ snmptranslate -On -IR system.sysUpTime.0
.1.3.6.1.2.1.1.3.0
