Xdebug module Output filename Configuration description

The Xdebug performance test output file name can be configured.

Default is Xdebug.profiler_output_name = cachegrind.out.%p

The%p is the PID of the server and will output "cachegrind.out.1408" files.

It may not be easy to test many files on a Web site.

There is no description of this parameter in the Chinese articles that are seen on the Internet.

I've got a description of it from the Xdebug website translated into Chinese.

Symbol	Meaning	Configuration sample	Sample file name
%c	CRC32 checksum value of current working directory	Trace.%c	Trace.1258863198.xt
%p	PID for the current server process	Trace.%p	Trace.5174.xt
%r	Random number	Trace.%r	Trace.072db0.xt
%s	Script file name (note)	cachegrind.out.%s	cachegrind.out._home_httpd_html_test_xdebug_test_php
%t	Unix Timestamp (seconds)	Trace.%t	Trace.1179434742.xt
%u	Unix Timestamp (microseconds)	trace.%u	Trace.1179434749_642382.xt
%H	$_server[' Http_host ']	Trace.%h	Trace.kossu.xt
%R	$_server[' Request_uri ']	Trace.%r	Trace._test_xdebug_test_php_var=1_var2=2.xt
%s	session_id (from $_cookie if set)	trace.%s	Trace.c70c1ec2375af58f74b390bbdd2a679d.xt
%%	% character	trace.%%	Trace.%.xt
Note This does not apply to the file name of trace file

From the table above you can find some parameters that are right for you.

For example, I want to generate an output file for each file.

Then I can use:

Xdebug.profiler_output_name = cachegrind.out.%s

Multiple domain names can also be used in combination

Xdebug.profiler_output_name = cachegrind.out.%h.%u.%s
