<h4>Filters</h4>
** Log Output Within the Table **
sll-output-data – filters table row array where array keys are column names and values is the output 
For example, we can use this filter to link IP addresses to a geo-location service:
<pre><code><?php
add_filter( 'sll-output-data', 'link_location_by_ip' );
function link_location_by_ip($item){

 //$item is a single row for columns with their values

 $item['ip'] = sprintf('<a target="_blank" href="http://infosniper.net/index.php?ip_address=%1$s&map_source=3&two_maps=1&overview_map=1&lang=1&map_type=1&zoom_level=11">%1$s</a>', $item['ip']);
 return $item;
}
?>
</code></pre>
<h4>Translation</h4>
If you would like to contribute, the POT file is available in the languages folder. Translation file name convention is sll-{locale}.mo, where {locale} is the locale of your language. Fore example, Russian file name would be sll-ru_RU.po.

This small plugin lets you monitor who logs into you site. I created this plugin because I could see that bots from china were trying to login to my site with the bettersecurity plugin but not if they were succesfull.
This small plugin saves the time and ip address from every user that succesfully logs in on wordpress and displays them on the admin dashboard. Only administrators can acces the logs.
Since version 1.2 its also possible to search within the logs.
If you have feedback on this plugin or problems with it (such as bugreports) please shoot me an email at williewonka341@gmail.com.
