# This requires the perf utility to be installed and the OS must be linux.
|
|
# Compile with CMAKE_BUILD_TYPE=RelWithDebInfo in the subdirectory "build".
|
|
# Run this script in the main source directory.
|
|
#
|
|
# This script sets up performance monitoring events to measure single
|
|
# document operations. Run this script with sudo when the ArangoDB
|
|
# process is already running:
|
|
#
|
|
# ./setupPerfEvents.sh
|
|
#
|
|
# Now you are able to recrod the event with:
|
|
#
|
|
# sudo perf record -e "probe_arangod:*" -aR sleep 60
|
|
#
|
|
# The above command will get sample data for 60 seconds. A file "perf.data" is
|
|
# written to the current directory. Dump the events in this file with:
|
|
#
|
|
# sudo perf script > perf.history
|
|
#
|
|
# This logs the times when individual threads hit the events.
|
|
# Use the program perfanalyis.cpp in this directory in the following way:
|
|
#
|
|
# sudo ./perfanalyis < perf.history > perf.statistics
|
|
#
|
|
# This will group enter and exit events of functions together, compute the time
|
|
# spent and sort by function. When finised remove all events with:
|
|
#
|
|
# sudo perf probe -d "probe_arangod:*"
|
|
#
|
|
# List events with:
|
|
#
|
|
# sudo perf probe -l
|
|
#
