You probably don't realize that your web sites, applications and servers are a data gold mine. This presentation features tools that will help you to gain insight into the (hidden) data of your stack.

The goals of this talk are:

• Aggregating and converting logs with Logstash and turning logs in to measuring points
• Centralizing logs and performing full-text search with ElasticSearch
• Capturing server performance metrics with CollectD and Munin
• Capturing application metrics with StatsD
• Visualizing all metrics in a single dashboard with Graphite
