A graphical interface for XHProf data built on MongoDB.
This tool requires that XHProf is installed, which is a PHP Extension that records and provides profiling data. XHGui (this tool) takes that information, saves it in MongoDB, and provides a convienent GUI for working with it.
- XHProf to actually profile the data
- MongoDB PHP MongoDB PHP extension
- MongoDB MongoDB Itself
- Support for Multiple Servers/Hosts using the same installation
- Fix for simplfied URLs with numeric query values
- Added support for enabling tracing on all calls if XHPROF_ENABLED cookie is present
Installing Xhgui requires 2 main steps. First is installing the xhgui
front-end, and the second is profiling a web application/site.
-
Clone or download
xhgui
from github. -
You'll need to install
mongodb
, andphp-mongodb
, at least version 1.3.0 of the php extension is required. -
Point your webserver to the
webroot
directory. -
Set the permissions on the
cache
cache directory to allow the webserver to create files. If you're lazy0777
will work. Runchmod -R 0777 cache
-
If your mongodb setup requires a username + password, or isn't running on the default port + host. You'll need to update
config/config.php
so that it can connect to mongod. -
You may wish to add indexes (recommended but optional) to improve the performance, you'll need to do this by using mongo console
On your command prompt (irrespective of Windows or *nix), open mongo shell using command 'mongo' and follow below commands to add the index:
$ mongo > use xhprof > db.results.ensureIndex( { 'meta.SERVER.REQUEST_TIME' : -1 } ) > db.results.ensureIndex( { 'profile.main().wt' : -1 } ) > db.results.ensureIndex( { 'profile.main().mu' : -1 } ) > db.results.ensureIndex( { 'profile.main().cpu' : -1 } ) > db.results.ensureIndex( { 'meta.url' : 1 } )
After adding indexes, you may notice you can navigate across pages faster.
-
Run the install script. This will download composer and use it to install the dependencies for xhgui.
cd path/to/xhgui php install.php
-
Setup your webserver. See below for how to setup the rewrite rules for nginx + apache.
Xhgui prefers to have URL rewriting enabled, but will work without it. For Apache you can do the following to enable URL rewriting:
-
Make sure that an .htaccess override is allowed and that AllowOverride is set to All for the correct DocumentRoot.
-
Make sure you are loading up mod_rewrite correctly. You should see something like:
LoadModule rewrite_module libexec/apache2/mod_rewrite.so
-
Xhgui comes with a
.htaccess
to enable the remaining rewrite rules.
For nginx & fast-cgi you can the following snippet as a start:
```
server {
listen 80;
server_name example.com;
# root directive should be global
root /var/www/example.com/public/xhgui/webroot/;
index index.php;
location / {
try_files $uri $uri/ /index.php?$uri&$args;
}
location ~ \.php$ {
try_files $uri =404;
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
```
The simplest way to get an application profiled, is to use external/header.php
.
This file is designed to be combined with PHP's auto_prepend_file directive. This can be enabled system-wide through php.ini
. Alternatively, you can enable
auto_prepend_file
per virtual host. With apache this would look like:
<VirtualHost *:80>
php_admin_value auto_prepend_file "/Users/markstory/Sites/xhgui/external/header.php"
DocumentRoot "/Users/markstory/Sites/awesome-thing/app/webroot/"
ServerName site.localhost
</VirtualHost>
With Nginx in fastcgi mode you could use:
server {
listen 80;
server_name site.localhost;
root /Users/markstory/Sites/awesome-thing/app/webroot/;
fastcgi_param PHP_VALUE "auto_prepend_file=/Users/markstory/Sites/xhgui/external/header.php";
}
Disk usage can grow quickly, especially when profiling applications with large code bases, or that utilize larger frameworks. One technique to keep the growth in check is to have Mongo automatically delete profiling documents once they reach a certain age. Decide on a maximum profile document age in seconds, you may wish to choose a lower value in development (where you profile everything), than production (where you profile only a selection of documents). The following command instructs Mongo to delete documents over 5 days (432000 seconds) old.
$ mongo
> use xhprof
> db.results.ensureIndex( { "meta.request_ts" : 1 }, { expireAfterSeconds : 432000 } )
