%description | |
logstash is a tool for managing events and logs. You can use it to collect logs, parse them, and store them for later use (like, for searching). Speaking of searching, logstash comes with a web interface for searching and drilling into all of your logs. | |
It is fully free and fully open source. The license is Apache 2.0, meaning you are pretty much free to use it however you want in whatever way. | |

In logstash 1.1.1 there is this bug https://logstash.jira.com/browse/LOGSTASH-463 affecting file inputs.
