Description of configuration options for [filter-xprofile] in account-server.conf
Configuration option = Default value Description
dump_interval = 5.0 the profile data will be dumped to local disk based on above naming rule in this interval (seconds).
dump_timestamp = false Be careful, this option will enable the profiler to dump data into the file with a time stamp which means that there will be lots of files piled up in the directory.
flush_at_shutdown = false Clears the data when the wsgi server shutdowns.
log_filename_prefix = /tmp/log/swift/profile/default.profile This prefix is used to combine the process ID and timestamp to name the profile data file. Make sure the executing user has permission to write into this path. Any missing path segments will be created, if necessary. When you enable profiling in more than one type of daemon, you must override it with a unique value like: /var/log/swift/profile/accoutn.profile
path = /__profile__ This is the path of the URL to access the mini web UI.
profile_module = eventlet.green.profile This option enables you to switch profilers which inherit from the Python standard profiler. Currently, the supported value can be cProfile, eventlet.green.profile, etc.
unwind = false unwind the iterator of applications
use = egg:swift#xprofile Entry point of paste.deploy in the server
