improving tracetree
HTrace is a tracing framework intended for use with distributed systems written in java.
The test that creates a sample trace (TestHTrace) takes a command line argument telling it where to write span information. Run mvn test -DspanFile=“FILE_PATH” to write span information to FILE_PATH. If no file is specified, span information will be written to standard out. If span information is written to a file, you can use the included graphDrawer python script in tools/ to create a simple visualization of the trace.
