Write all login attempts where both username and password are supplied to a log file. The logfile is relative 
to error.log and is called ‘login.log’, the format : “TIMESTAMP USERNAME SUCCESS/FAILURE”.
In practice this plugin is a rewritten version of the wp_authenticate_username_password function from user.php and replaces 
it in the login process.

This plugin logs the usage of deprecated files, functions, and function arguments. It identifies where the deprecated functionality is being used and offers the alternative if available.
This is a plugin for developers. WP_DEBUG is not needed, though its general usage is strongly recommended. Deprecated notices normally exposed by WP_DEBUG will be logged instead.
This plugin also logs incorrect function usage, which WordPress started reporting in 3.1.
Please report any bugs to plugins in a <a href="https://wordpress.org/support/plugin/log-deprecated-notices" rel="ugc">support thread</a>.
This is young software. It works, but there’s a lot left on the todo (check out the Other Notes tab). Have an idea? Let me know.
<h3>Ideas</h3>
These are the various things on the @todo:
<ul>
<li>Plugin identification. Also, an unobstrusive note on plugins page next to said plugins.</li>
<li>Perhaps the ability to auto-purge the log.</li>
<li>Ability to filter on file or plugin in which the deprecated functionality is used.</li>
<li>Offer some kind of better multisite support.</li>
</ul>
Want to add something here? I’m all ears. plugins at <a href="http://andrewnacin.com/" rel="nofollow ugc">andrewnacin.com</a> or @<a href="http://twitter.com/nacin" rel="nofollow ugc">nacin</a> on Twitter.
I will prioritize these tasks based on feedback, so let me know what you’d like to see.

Very easy to use and useful for debugging your own plugins.

Senzill d'utilitzar i necessari per fer la depuració de les extensions.
