Logs and statistics are key to helping us understand all of the ins and outs of our complex environments. Tailing through logs is a great way to fall asleep, but far from an effective way to determine the state of a given system. Logstash is a spectacular open source tool that in conjunction with a vast array of plug-ins, can be used to help you make sense of your environment. It enables you to extract the relevant data from your logs so that you can make sense of them. Based on this information, you can find performance bottlenecks, errors etc...all of which can be use to improve the quality and speed of a Drupal application.
