Question:
I've got a strange issue. I've setup XDebug to profile a PHP application we're working on. I believe everything is setup correctly but I get no output when I run it. My configuration looks like this:
zend_extension="/usr/local/lib/php/extensions/no-debug-non-zts-20060613/xdebug.so [XDebug] xdebug.profiler_append = 1 xdebug.profiler_enable = 0 (I've tried this both on and off) xdebug.profiler_enable_trigger = 1 xdebug.profiler_output_dir = "/debug/xdebug/profiler_output_dir" xdebug.profiler_output_name = "cachegrind.out.%p"
All the phpinfo()
settings match up like they should. The permissions on the output directory are set to 777 right now just so I can test it. I've tried using a directory under public_html as well but no luck. The URL I'm using to launch the profiler is:
http://example.com/my_page.php?XDEBUG_PROFILE -or- http://example.com/my_page.php?XDEBUG_PROFILE=1
Neither works. Any help would be GREATLY appreciated!! This app has a 5-6 second page load time and I haven't been able to trace it through code.
Solution:1
Comment out xdebug.profiler_output_dir
and xdebug.profiler_output_name
and see whether you can find the output under /tmp/
.
Solution:2
There is also problem with /tmp folders on some distributions, i couldnt get output on centos 7 and then i found this
So, i have set
xdebug.profiler_output_dir=/home/jirka/profile
set 777 and its ok now.
Solution:3
Another possible cause of this issue is the permissions on the folder of profiler_output_dir.
Adding write permissions to the group and owner resolved the issue for me:
sudo chmod go+w /home/dimitris/cachegrind/
Solution:4
Also, beware of access restrictions, such as access rights, groups, owner and SElinux...
Solution:5
The full path was required, not just the path:
xdebug.profiler_append=1 xdebug.profiler_output_dir ="/home/username/debug/xdebug/profiler_output_dir" xdebug.profiler_output_name = "cachegrind.out.%s.%H"
