[Xymon] xymonnet yellow alarm

Hi,

Is there a way to configure the number of seconds where xymonnet will start to do a yellow alarm ?

I can't find anything...

I remember it was doing yellow alarms only if time to execute all tests is greater than 300 seconds. It seems it's now 20 seconds on my xymon server 4.3.21-4.el7.terabithia.

Any hint is welcome.

Cheers, Francois.
