My VS is unknown (Blue) on my LTM but available on my GTM (Green)

Hi,

 

I'm working on GTM currently. I'm wondering why when I add a LTM on my GTM and discover the existing VS, my GTM find them and considers they are available (Green) when at the same time, on my LTM the same VS are in an unknown state (Blue). There is no Health Check on my LTM or on my GTM.

 

Is there a way to reflect the blue status on the GTM, or it's a normal behavior ? Can you tell me what is the logic behind this choice, I just working on it since few weeks.

 

Regards
