Php - DTracing PHP
|
|
|
|
These scripts trace the PHP programming language, and require the PHP
|
|
DTrace extension module to be installed and enabled.
|
|
|
|
The PHP DTrace provider was written by Wes Furlong, and is available
|
|
for download both as source and in binary form. The easiest instructions
|
|
are currently at,
|
|
|
|
http://blogs.sun.com/shanti/entry/dtrace_support_for_php
|
|
|
|
which were written for Solaris and the coolstack distribution of PHP.
|
|
The steps are roughly,
|
|
|
|
1. Download the extension library from the URL above
|
|
2. Copy the library to your php/extensions/* directory
|
|
3. Edit your php.ini and add,
|
|
extension="dtrace.so"
|
|
|
|
The website with the PHP DTrace provider source is,
|
|
|
|
http://pecl.php.net/package/DTrace
|
|
|
|
Here you can fetch the source to build the library yourself, especially
|
|
if Solaris binaries from the previous URL aren't going to work for you.
|
|
|
|
Since the DTrace PHP provider may be developed further, there is a chance
|
|
that it has changed slightly by the time you are reading this, causing
|
|
these scripts to either break or behave oddly. Firstly, check for newer
|
|
versions of the DTraceToolkit; if it hasn't been updated and you need
|
|
to use these scripts immediately, then updating them shouldn't take
|
|
too long. The following was the state of the provider when these scripts
|
|
were written - check for changes and update the scripts accordingly,
|
|
|
|
provider php {
|
|
probe function-entry(function, file, lineno)
|
|
probe function-return(function, file, lineno)
|
|
};
