Java-driver perf log analysis tool

Lists top messages by level from java-driver fallout test logs.

Features

  • Process java-driver fallout logs, consolidate multi-line messages
  • Print top N (default=10) messages per level
  • Read from file or std-in
  • Substitutions for variable fields to improve matching (IP addresses, jar versions, line numbers etc)
  • Compare top messages between two files

Todo / wishlist

  • Use fallout API to download result/run tests automatically
  • Compare more than two files
  • Show progress during processing

Usage

(stacktraces truncated for readability)

Show top messages from perf run:

Tracing node-list and control connections

Groups logs by hostId/broadcast-address to help debug issues with running out of available connections (NoHostsAvailable exception)

Usage

Here is an example output showing the interesting lifecycle events for one host, the rest of the output has been truncated for brevity.
