Overview

The TDA Thread Dump Analyzer for Java is a small Swing GUI for analyzing Thread Dumps and Heap Information generated by the Sun Java VM (currently tested with 1.4.x, 1.5.0_x, 1.6.0_x, 1.7.0_x and 1.8.0_x releases). It parses the thread dumps and class histograms from a provided log file. TDA needs at least Java 1.4.2_x to run.

It provides statistic informations about the found thread dumps, gives information about locked monitors and waiting threads. It can diff between threads to look for similarities and has a "long-running-thread" detection. It also provides overview of heap objects at a thread dump, if class histogram was logged.

Features are in detail:

The emphasis of the TDA is to provide analysis support of offline information gathered from production environments.

In addition to TDA you might find the GCViewer helpful. It parses the output of the garbage collector from a loggc file and displays it graphically, so you can analyse the memory usage over the time. See here: https://github.com/chewiebug/GCViewer
