The files in this repo help use logstash to aggregate and process OpenStack logs.

In the example below, agent.conf is copied to /etc/logstash and patterns dir is copied to /etc/logstash. You must include the default grok-patterns in the same directory. Here is an example to start logstash with these patterns on each OpenStack node.

java -Djava.library.path=/usr/share/logstash -jar /usr/share/logstash/logstash-1.1.5-monolithic.jar agent 
    -f /etc/logstash/agent.conf 
    --grok-patterns-path /etc/logstash/patterns
