Hi Brad,
thanks for the answer.
Yes that's what I put in place: KO as a receive string.
But I think i'm confused because of this SOL: https://support.f5.com/kb/en-us/solutions/public/12000/800/sol12818.html (the table with results of matching)

(For info I more or less follow the best practice 'Timeout = 3x Interval + 1')
Br,

NimbostratusHealth monitors are first exact match. If there are more than one, it takes the first. I have seen issues with monitors because of this. Also, keep in mind that health monitors don't look at the entire page.
