Testing log stash filter against data

Hi All,

When i try to test a log stash filter, against some data, like below

/opt/logstash/bin/logstash -f /etc/logstash/conf.d/11-tomcat-filter.conf < /home/gibu_test/data4

All i get in the output is:
Settings: Default pipeline workers: 2
Pipeline main started
Pipeline main has been shutdown
stopping pipeline {:id=>"main"}

What does this mean?why isn't it able to parse the data?

Added --verbose and --debug, seeing output now.

Does this work for you after adding the data? If not can you paste the logstash config.

Unless your 11-tomcat-filter.conf contains a stdin input and e.g. a stdout output you don't have any inputs or outputs.
