TDA goal is to provide a small utility helping offline analysis of production enviroments like application servers.

There is a quite nice Thread Dump Analysis Tool for Websphere environments but which only works with IBM JDKs. Motivation for this little tool was to have something similar for Sun JDKs.

The TDA Thread Dump Analyzer is a small Swing GUI for analyzing Thread Dumps generated by the Sun Java VM (currently tested with 1.4.x releases). It parses the thread dumps from a provided log file.

It provides statistics 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.

Here are some key features of "TDA":
parsing all thread dumps of a log file, using a specified regular expression for log file time stamps (thread dumps don't have any date information by default), displaying them in a tree.
Display of statistic data about the found thread dumps, display of monitors, waiting, sleeping and locking threads,
integrated class histogram analysis for a specific thread dump (using the -XX:+PrintClassHistogram option of the VM), can also be parsed from a second file, if loggc-Option was used (to log to a different VM).
parser interface for integrating dump parser for other VMs
displays deadlock information from the thread dump.

Requirements:
Java Environment

What's New in This Release:
More than one logfile can be opened at a time.
A history of recently opened files was added.
Multiple regular expressions can be used for date parsing in settings, but only one can be active at one time.
