I am using snmp plugin in logstash for getting snmp trap alarms.
The plugin is not decoding the trap name but the field is getting decoded as shown below:
```
{
"SNMPv2-MIB::snmpTrapOID.0" => "BroadworksFault::systemFaults.8901",
}
```
But while using the head command on the MIB file I can find it decoded correctly as shown below:
ubuntu@prod-platform:/usr/share/logstash/vendor/bundle/jruby/1.9/gems/snmp-1.2.0/data/ruby/snmp/mibs$ head BW-ExecutionDatalessFault.yaml
---
systemFaults: '0.1'
bwPMExecutionDatalessServerLaunched: 0.1. **8901**
bwPMExecutionDatalessServerShutDown: 0.1.8902
bwPMExecutionDatalessServerRestarted: 0.1.8903
bwPMExecutionDatalessServerDeath: 0.1.8904
bwDXSSipAuthenticationFailure: 0.1.8905
bwDXSAclViolation: 0.1.8906
bwDXSIMSRetrieveMessageError: 0.1.8907
bwDXSIMSRetrieveMailBoxInfoError: 0.1.8908
8901 is not getting decoded to "bwPMExecutionDatalessServerLaunched" as shown in the output.
Could any one please help me on this.
Thanks
George
