Am I misunderstanding if/else statements?

Hi,

I have a bunch of logstash (2.4.0) nodes with this output config:
output {
if [environment] == "stage" {
elasticsearch {
hosts => [ "elasticsearch-01" ]
index => "logstash-stage-%{+YYYY.MM.dd}"
}
} else {
elasticsearch {
hosts => [ "elasticsearch-01" ]
index => "logstash-%{+YYYY.MM.dd}"
}
}
}
The idea is of course that logs with the environment field set to stage should go into the logstash-stage index. This is not working as intended because it goes to both indices i.e. the same event is found under both logstash-stage and logstash-. This only happens for events with environment == stage, other events only goes to logstash- as they should. What am I doing wrong?

Thanks,

Your configuration looks correct. If you're storing your configuration file(s) in /etc/logstash/conf.d, do you have any other files there (like one with an elasticsearch output)? Logstash will read all files in that directory.

I figured it out... it's in the right index but Kibana evaluates both indices since logstash-* ofcourse matches logstash-stage-%{+YYYY.MM.dd} too. I renamed the stage one to logstage and all is good.

Thanks!
