#
# GOOGLE PERF TOOLS
#
# Repository: https://github.com/gperftools/gperftools#readme
# Documentation: https://gperftools.github.io/gperftools/
#
# Install (Ubuntu):
# sudo apt-get install google-perftools libgoogle-perftools-dev
# Note: dependencies above are already installed in docker
#
# Usage:
# 1. To enable the gperftools you need to compile with the -DWITH_PERFTOOLS=ON compiler flag. You can use CCUSTOMOPTIONS above to set it for the dashboard compiler
# 2. Configure the variable below accordingly to your needs
# 3. run the worldserver with the "./acore.sh run-worldserver"
# 4. run "killall -12 worldserver" This command will start the monitoring process. Run "killall -12 worldserver" again to stop the process when you want
# 5. At this time you will have the .prof file ready in the folder configured below.
# Run "google-pprof --callgrind <path/of/worldserver/bin> </path/of/prof/file>" This will generate a callgrind file that can be read with
# QCacheGrind, KCacheGrind and any other compatible tools

# If set to any value (including 0 or the empty string), use ITIMER_REAL instead of ITIMER_PROF to gather profiles.
# In general, ITIMER_REAL is not as accurate as ITIMER_PROF, and also interacts badly with use of alarm(),
# so prefer ITIMER_PROF unless you have a reason prefer ITIMER_REAL.
