GTM Custom SMTP Monitor

Hello;

 

I am trying to use this usefull custom SMTP script to monitor my GTM Pool: https://devcentral.f5.com/wiki/AdvDesignConfig.SMTP_scripted_monitor.ashx

 

For some strange reason, I see that the monitor is only testing one node of a total of 4 nodes. Doing so, the monitor is placing the other three out of the pool.... I did set it up at the group level.

 

Please advise.

 

Thank you
