GTM Monitor

I am monitoring a generic host on TCP port 21 from GTM. The monitor is successful, however I cannot see any of the traffic with tcpdump. I know the monitor is working through testing it, I just cannot see the monitor traffic. I have no problems seeing the monitor traffic when I create the same pool member IP and monitor under "local traffic". Any ideas?

 

 

Thanks in Advance

  • Your LTM in the same DC may be performing the monitoring, do you tcpdump there to confirm.
  • Thanks Jason,

     

    That is exactly what is happening. One of the LTMs in that DC is health checking and sharing status via iQuery.
  • hi... diggin up an old thread here, but just wondering if there is a way to disable this behaviour and have the GTM monitor the servers itself rather than rely on the LTM which has no knowledge of the servers.

     

  • Create a "Proper Pool" on the GTM and assign only the GTM's that you want to initiate the healthcheck. Then assign that Prober pool to the Generic host.
