Profiling policy performance in CFEngine
Loïc Pefferkorn has created the cfe-profiler. It is a library that times the execution of CFEngine bundles in your policy. Let's take a look.
Here is the output from one of my production hosts:
# LD_PRELOAD=/home/neil/src/cfe-profiler/cfe_profiler35.so cf-agent Cfe-profiler-0.1: a CFEngine profiler - http://www.loicp.eu/cfe-profiler *** Sorted by wall-clock time *** Time(s) Namespace Type Bundle 3.30 default agent efl_main 3.14 default agent efl_bug2638 1.20 default agent efl_service 0.58 default agent efl_packages 0.53 default common paths 0.36 default agent email 0.31 default agent efl_copy_files 0.27 default agent postfix_main ....
Cfe-profiler list the execution time of each bundle in descending order. A bundle like cfl_main calls many other bundles. Its time is an accumulation of all the bundles it calls. Those with large complex policies will welcome this tool. Keep up the good work Loïc!
