Error starting logstash


(elk of the forest) #1

Im using this command to start logstash:

$ bin/logstash -f logstash-config/02-beats-input.conf -f logstash-config/10-syslog-filter.conf -f logstash-config/30-elasticsearch-output.conf

Logstash gives this error.

Can you please run java -version and post the output here?

Thanks I fixed the problem. The Java version was 1.6, fixed the JAVA_HOME & PATH variables and got it working.
