Monitoring number of AP per WLC

[Artii]

Hi, has anybody a template or plugin to monitor exact number of APs per WLC? I only find this old topic http://forums.cacti.net/viewtopic.php?f=12&t=40326 and i try to apply template and script and it works only for WLC 5500.
For 4400 graphs show that there are 0 APs.

Thanks
