How to add DTrace probes to your application
By rnl on Jun 30, 2009
MC Brown and I co-presented a session at CommunityOne West on how to add probes to applications, using MySQL and PostgreSQL as case study. In the presentation, I used a very simple example to demonstrate how easy it is to add probes. If you want to try out yourself, here is the code. Extract the files, run gmake (or gnumake on OS X) to build, and run the executable in one terminal and the DTrace script in another terminal to see the output from the probes. To see more complicated examples, checkout the MySQL or PostgreSQL source code.
