ruby−prof − A fast ruby profiler
ruby−prof options <script.rb> [−−] [profiled−script−command−line−options]
ruby−prof is a fast profiler for ruby. It can be used as a stand−alone program (that this man page documents) or as a ruby library. Simply run the ruby program you want to profile using ruby−prof : ruby−prof script.rb At the end of execution the time spent in each method is displayed.
−p, −−printer=printer
Select a printer:
flat − Prints a flat profile as text (default).
flat_with_line_numbers − same as flat, with line numbers.
graph − Prints a graph profile as text.
graph_html − Prints a graph profile as html.
call_tree − format for KCacheGrind
call_stack − prints a HTML visualization of the call tree
dot − Prints a graph profile as a dot file
−m, −−min_percent=min_percent
The minimum percent a method must take before being included in output reports. this option is not supported for call tree.
−f, −−file=path
Output results to a file instead of standard out.
−−mode=measure_mode
Select what ruby−prof should measure:
process − Process time (default).
wall − Wall time.
cpu − CPU time (Pentium and PowerPCs only).
allocations − Object allocations (requires patched Ruby interpreter).
memory − Allocated memory in KB (requires patched Ruby interpreter).
gc_runs − Number of garbage collections (requires patched Ruby interpreter).
gc_time − Time spent in garbage collection (requires patched Ruby interpreter).
−s, −−sort=sort_mode
Select how ruby−prof results should be sorted:
total − Total time
self − Self time
wait − Wait time
child − Child time
−−replace−progname
Replace $0 when loading the .rb files.
−v |
Show version, set $VERBOSE to true, profile script if option given |
||
−d |
Set $DEBUG to true |
−R, −−require−noprof lib
require a specific library (not profiled)
−E, −−eval−noprof code
execute the ruby statements (not profiled)
−x, −−exclude regexp
exclude methods by regexp (see method elimination)
−X, −−exclude−file file
exclude methods by regexp listed in file (see method elimination)
−−exclude−common−cycles
make common iterators like Integer#times appear inlined
−−exclude−common−callbacks
make common callbacks invocations like Integer#times appear inlined so you can see call origins in graph
−h, −−help
Show help message
−−version
Show version 0.13.1
