Hi everybody 
I try to use SNMP with logstash, but my configuration or something is wrong and I don't find any information who can help me 
First : I don't understand how it should work,
snmptrapd must run or not ? Or Logstash work like snmptrapd and receive trap on the port 162?
I have try this configuration :
input {
snmptrap {
port => 162
community => 'public'
type => 'snmptrap'
yamlmibdir => "/opt/logstash/vendor/bundle/jruby/1.9/gems/snmp-1.2.0/data/ruby/snmp/mibs"
}
}
output {
stdout {
codec => rubydebug
}
}
I have try to use it without port, community option but nothing change.
Tcpdump recive the trap
I have prepare some enterprise mib in yaml format for the next step
Thank if someone can help me a little
Vost
