wordpress add filter not working

I'm开发者_JAVA技巧 trying to replace the admin dashboard function that displays the 'Right Now' panel. I have my own function displaying other info but it's simply not picking up.

add_filter('wp_dashboard_right_now', 'wp_dashboard_my_summary', 1, 0);

Where am I going wrong?

Given WP Plugin API Filter Reference, there is no such filter wp_dashboard_right_now .

There are a few actions that you can use tough ( carefull they are not fiters but actions ) :

• right_now_content_table_end
• right_now_table_end
• right_now_discussion_table_end
• rightnow_end
• activity_box_end
