class ActiveProfiling::Railtie
Constants
- DEFAULT_AR_BACKTRACE_LOGGER_OPTIONS
These settings are the default values used for the
ActiveRecord
backtrace logger.-
:enabled
- Enables backtrace logging of SQL queries so you can see where your queries originate. -
:verbose
- Logs all backtrace lines. Normally we have a:matcher
option that you can use to filter out lines you want to log, but this is a quick method to bypass that matching completely. -
:log_level
- The log level to use when logging SQL backtraces. -
:matcher
- A Regexp that is used to match caller lines in the backtraces being logged. By default, this is set to /^#{Rails.root}(?!(/vendor/rails|/.bundle))/ so that only lines in your application code are logged.
-
- DEFAULT_GC_STATISTICS_OPTIONS
These settings are the default values used when profiling GC statistics. When enabled, statistics are gathered for every request. You can also gather statistics on a per-block basis using ActiveProfiling.gc_statistics directly.
-
:enabled
- For logging GC stats. Output is dumped into the log on each request. -
:disable_gc
- Whether or not we're disabling actual garbage collection during statistics gathering. If set to true, the garbage collector will be disabled for the duration of the action and then re-enabled at the end of the action. This allows you to call GC.start whenever you need to and see results as you go. -
:log_level
- The log level to spit the GC statistics to.
-
- DEFAULT_PROFILER_OPTIONS
These settings are the default values used when running RubyProf on every request. You can also use the profiler directly by using the ActiveProfiling.ruby_profiler method.
-
:enabled
- Enable profiler on requests. -
:measure_mode
- The ruby-prof measure mode. The default is RubyProf::PROCESS_TIME. Use Symbols for this instead of the actual RubyProf constants (i.e.:memory
instead of RubyProf::MEMORY) so you can have your configuration options in your environment set up without having to require ruby-prof. -
:disable_gc
- Whether or not we're disabling garbage collection during profiling. This is useful when you're profiling memory usage, where you should disable garbage collection as ruby-prof will otherwise record information on GC on the method that causes GC rather than the methods that allocate the memory. -
:printer
- The RubyProf printer to use. See the RubyProf docs for details. The default is RubyProf::FlatPrinter. Use Symbols in this option, i.e.:flat
instead of RubyProf::FlatPrinter. (Note that the FlatPrinterWithLineNumbers printer is called:flat_with_line_numbers
here.) -
:call_tree_prefix
- The prefix to use for:call_tree
files. Some programs like to look for files named “callgrind.out.*”, while others like to look for “cachegrind.out.*”. -
:output
- Where to direct the output from the profiler. If set to:stdout
, well, then it's sent to $stdout. When set to:log
, it shows up in the log file. When set to:file
, it gets put inRails.root/log/profiling/
in a sensible manner. The default depends on the:printer
being used:-
:file
-:graph_html
,:call_stack
,:call_tree
,:dot
-
:log
-:flat
,:flat_with_line_numbers
,:graph
and anything else
-
-
:log_level
- The log level to spit the logging information into when using:log
for:output
. The default is:info
. -
:printer_options
- Options to pass to the profiler printer. The default is::printer_options => { :min_percent => 1, :print_file => true }
-
