Description

Complex distributed systems like Zookeeper tend to fail in strange ways that are hard to diagnose. The objective is to build a tool that helps understand when and where these problems occurred based on Zookeeper's traces (i.e., logs in TRACE level). Minor changes to the server code will be needed.
