Active Monitoring VMWare ESXi Host

Hi all,

I want to monitor a VMWare ESXi Host in a active manner. In other words, I want that this host send performance informations to my monitor machine instead of my monitor machine ask for these informations. In Xen I can put a script or a Java application to run at Domain0, but in VMWare ESXi this seems to be impossible. Is there a way to do this?

Thank you all!
