<p>LogStore can be used to log (important) data from within your plugin.<br />
It provides a simple interface to log entries and a friendly administration interface for viewing and managing the log entries.</p>
<p>While LogStore can be used to log debug output or system events, it’s main intention is to log more extensive data, such as:</p>
<ul>
<li>system emails sent your users</li>
<li>data received from remote API calls</li>
</ul>
<h3>Usage</h3>
<p>To use LogStore in your plugin, add the following line to your plugin’s ‘plugins_loaded’ callback function:</p>
<pre><code>if (class_exists('LogStore')) $this->log = new LogStore('slug', __('Title'));
</code></pre>
<ul>
<li>The ‘slug’ should be a unique identifier for your logger.</li>
<li>The ‘Title’ will be the title used in menu entries, options and page titles.</li>
</ul>
<p>Once that’s done you can then start logging your data from anywhere within your plugin by using the following:</p>
<pre><code>if (!empty($this->log)) $this->log->log(__('My log message'), $my_log_data, 'status', 'tag');
</code></pre>
<ul>
<li>‘My log message.’ is any arbitrary message to describe your log entry.</li>
<li>$my_log_data is the extended data you want to log. This can be either an array or string.</li>
<li>‘status’ is one of ‘none’, ‘ok’, ‘warn’, ‘critical’ or ‘fatal’.</li>
<li>‘tag’ can be any kind of singular tag to  further classification to your log entries.add</li>
</ul>
<p>If you use LogStore in your plugin, you should check for it’s presence in</p>
<ul>
<li>your ‘plugins_loaded’ callback</li>
<li>your plugin activation callback</li>
</ul>
<p>You should either make LogStore use optional or notify the user that they need to install LogStore for your plugin to work properly.</p>
<h3>Plugin Hooks</h3>
<p>In the following hooks, <code>*myname*</code> stands for the name with which you instanciated the LogStore class.</p>
<h4>Action Hooks</h4>
<ul>
<li><code>logstore_init-*myname*</code> – runs during the execution of WP’s <code>init</code> action hook, passes a single boolean parameter indicating if logging is active or inactive for this logger</li>
</ul>
<h4>Filter Hooks</h4>
<ul>
<li><code>logstore_new_entry-*myname*</code> – runs during the creation of a new entry, passes a single array containing all values for that entry (‘time’, ‘message’, ‘data’, ‘status’ and ‘tag’)</li>
<li><code>logstore_entry-*myname*</code> – runs before displaying an entry on screen, passes a single array containting all values for the entry (‘time’, ‘message’, ‘data’, ‘status’ and ‘tag’)</li>
<li><code>logstore_format_entry_data-*myname*</code> – runs before displaying the formatted data on screen, passes the formatted data as string</li>
</ul>
<h3>Further Notes</h3>
<p>Please note that the ‘bulk actions’ in the log viewer are currently not<br />
working.</p>


LogStore

LogStore is a 'meta' plugin that allows other plugins to log data easily.

tarppa

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


WP Login Logging

Write all login attempts to a logfile by replacing default wp_authenticate_username_password functionality
