}

for example , i need to work with the variable ERICSSON-SNF-ALARM-MIB::snfAlarmActiveModelIndex , in the real the variable is compost with ERICSSON-SNF-ALARM-MIB::snfAlarmActiveModelIndex + OID, the first part is common for all , the second part (OID) change, so my first work is find , with regexp , the correct variable i think

"ERICSSON-SNF-ALARM-MIB::snfAlarmActiveModelIndex.10.65.67.84.73.86.65.84.73.79.78.11.7.226.9.18.15.46.11.5.43.2.0.125" => "1321"

ERROR_CODE = ${ERICSSON-SNF-ALARM-MIB::snfAlarmActiveModelIndex*}

thank you for all

ok I did parse the variable with grok debugger

ad ex
"SNMPv2-MIB::snmpTrapOID.0" => %{GREEDYDATA:state}
"ERICSSON-SNF-ALARM-MIB::snfAlarmActiveOriginatingSource.*" => "%{IPV4:ipsource}"

but i have error with logstash

match => { "message" => "SNMPv2-MIB::snmpTrapOID.0" => %{GREEDYDATA:state} }
