Removing alert from "current non-green" view ? 🔗 link

Hello,

 
I'm supervising a lot of Virtual Machines (VMware ESX 4.1) with Xymon
and of course everything is ok. But I noticed an annoying behaviour with
this setup : I got many alerts from the NTP test (flip-flop). What is
the best solution to prevent this behaviour ?

 
Cheers,
