logstash json attempt (logstash 1.2.2)

README.md

Alright, so I run logstash 1.2.2 like so:

$ java -jar ~/software/solrlogmanager/logstash_deploy/logstash-1.2.2-flatjar.jar agent -f logstash.conf 

And it outputs this:

Using milestone 2 input plugin 'file'. This plugin should be stable, but if you see strange behavior, please let us know! For more information on plugin milestones, see http://logstash.net/docs/1.2.2/plugin-milestones {:level=>:warn}
Using milestone 1 codec plugin 'json'. This plugin should work, but would benefit from use by folks like you. Please let us know if you find bugs or have suggestions on how to improve this plugin.  For more information on plugin milestones, see http://logstash.net/docs/1.2.2/plugin-milestones {:level=>:warn}
^CInterrupt received. Shutting down the pipeline. {:level=>:warn}

But then it just sits there and I get no more output - expected to see the event output to stdout.

example_logfile.log

logstash.conf

input {
  file { 
    path => "/home/jadams/projects/uspto/USPTO_dir_api/analytics/example_logfile.log" 
    type => ui

    # This format tells logstash to expect 'logstash' json events from the file.
    codec => json
  }
}

output {
  stdout { debug => true codec => "rubydebug" }
}
