Having trouble running Logstash as a service

Elastic Stack Logstash
1

Hello,

I've been experimenting with logstash for a little bit now but mostly from command line. I've had trouble getting it working properly when run as a service.

Using logstash 2.3.4 install via rpm.

sudo service logstash configtest - > Configuration OK

I start the service, nothing ever outputs to /var/log/logstash/logstash.log

I did see this thread LogStash 2.2 start as a service does not read config file

Seems like going to the logstash.log is the way to go, but mine never becomes populated.

Trying to figure out how to troubleshoot this issue. Thank you.

Just to provide more details on what I have tried so far..

  1. Running service as user logstash

  2. Add "--verbose" option in LS_OPTS within /etc/init.d/logstash

  3. Verified service was running using "ps -ef | grep logstash". Command line below:
    logstash 4643 1 0 12:55 pts/1 00:00:00 bash /opt/logstash/vendor/jruby/bin/jruby --1.9 -J-XX:+UseParNewGC -J-XX:+UseConcMarkSweepGC -J-Djava.awt.headless=true -J-XX:CMSInitiatingOccupancyFraction=75 -J-XX:+UseCMSInitiatingOccupancyOnly -J-XX:+HeapDumpOnOutOfMemoryError -J-Djava.io.tmpdir=/var/lib/logstas -J-Xmx1g -J-XX:HeapDumpPath=/opt/logstash/heapdump.hprof /opt/logstash/lib/bootstrap/environment.rb logstash/runner.rb agent -f /etc/logstash/conf.d -l /var/log/logstash/logstash.log --verbose

  4. Changed permissions (using chmod -R for recursive) to logstash:logstash on the following directory structures:
    /opt/logstash
    /etc/logstash
    /var/lib/logstash
    /var/log/logstash

  5. I run ls -al /var/log/logstash while the service is running, it seems like nothing is ever outputted to these logs? Their sizes are always zero.
    total 4
    drwxrwxr-x 2 logstash logstash 66 Mar 20 20:59 .
    drwxr-xr-x. 8 root root 4096 Mar 20 17:59 ..
    -rw-r--r-- 1 logstash logstash 0 Mar 21 12:55 logstash.err
    -rw-r--r-- 1 logstash logstash 0 Mar 20 20:59 logstash.log
    -rw-r--r-- 1 logstash logstash 0 Mar 21 12:55 logstash.stdout

I certainly appreciate any help.
