Hi Dear,
I am completely new to webgrind and Xdebug so want some help from you guys.
First clear me the os in which i should install the webgrind and then
the file and location in which we have to make the modifications.
Note:I am currently using wamp server.

[...] 后来阅读了Profiling PHP with Xdebug and Webgrind 这篇文章,解释了xdebug.profiler_enable_trigger的作用:If you enable this option, profiles will only be generated if you pass a GET/POST parameter or cookie with the name XDEBUG_PROFILE, e.g., http://localhost/script.php?XDEBUG_PROFILE. You must not enable xdebug.profiler_enable if you use this option. [...]

Thanks for all the help above.

I’ve been hair pulling for the last 2 days to get Webgrind running, receiving a file read error on xdebug.profiler_output_dir.

The solution (for me at least): changing xdebug.remote_host from ‘localhost’ to 127.0.0.1. It’s probably written somewhere but I suffer from the disease of !RTFM

Also please do not forget Webgrind may have no permissions to read profiler output files. For example if these files are located not in Webgrind server root.

So, the default php open_basedir restriction may be in effect.

If so, add to configuration of VirtualHost

php_admin_value open_basedir none
Or in similar way set profiler output files accessible from webgrind installation.

This is slightly off topic, but maybe you can help. I have installed XDebug for php5.3.2VC9TS on a windows 7 box and I use a virtual Ubuntu 9.04 with kcachegrind installed to produce the visuals.

But when I enable the profiler I get not output in the browser. I do get output files that I can produce visuals of. But the browser says the connection was reinitialized during the request and refuses output.

Any idea’s?

This is in my php.ini:

[XDebug]
zend_extension=d:\php532\ext\php_xdebug-2.0.5-5.3-vc9.dll ; if xdebug enabled, webserver doesn’t output
xdebug.profiler_enable=1
xdebug.profiler_output_dir=d:\tmp
xdebug.profiler_output_name = cachegrind.out.%t.%p

Hello,

I am running Ubuntu 9.10 and have installed everything as stated above. Everything seems to be working to the point that the grind files are generated. However when I go into webgrinds web interface and click update it just shows a message telling me to select a grind file. No matter which file I choose I get the same message. I have verified that the grind files actually contain data. I am not sure if there is a permissions problem reading them or not.

jocrawfo@jcrawford:~/installed/webgrind/grinds$ namei -m ~/installed/webgrind/grinds/cachegrind.out.1268144184.18372
f: /home/jocrawfo/installed/webgrind/grinds/cachegrind.out.1268144184.18372
drwxr-xr-x /
drwxr-xr-x home
drwxrwxr-x jocrawfo
drwxr-xr-x installed
drwxr-xr-x webgrind
drwxrwxrwx grinds

jocrawfo@jcrawford:~/installed/webgrind$ ls -la | grep grinds
drwxrwxr-x 2 www-data www-data 4096 2010-03-09 09:26 grinds

Any assistance would be appreciated.

Thanks,
Joseph Crawford

Nice to know, for different cachegrind files per host you can use %H in the profiler_output_name, according to http://www.xdebug.org/docs/all_settings#trace_output_name
