Redirect Admin User in Dashboard

I am currently trying to setup a redirect so that my admin users are redirected to a page other than the dashboard within the wordpress administrator interface.

If I leave out my conditional, the redirect works, but then it also redirects non-administrator users as well and I don’t want this.

Here is the code I have within functions.php

add_filter('login_redirect', 'dashboard_redirect');
function dashboard_redirect($url) {
  global $current_user;
  get_currentuserinfo();
  $level = (int) $current_user->wp_user_level;

  if ( $level > 10  ) {
    $url="wp-admin/edit.php";
  }

  return $url;
}     

You should not use Userlevels. Userlevels have been replaced in WP 2.0 and have been officially deprecated since 3.0

add_filter( 'login_redirect', 'dashboard_redirect' );
function dashboard_redirect( $url ) {
    if ( current_user_can( 'manage_options' ) ) {
         $url = esc_url( admin_url( 'edit.php' ) );
    }

    return $url;
}    

Will do what you want.
