GTM health monitor fails on pool, but not on member.

I am running GTM 11.4.1 HF1.

 

If I assign the default HTTP health monitor to a GTM pool, the pool goes red. If I remove the pool health check and add the HTTP health monitor to the member that's in the pool, the pool goes green.

 

The GTM has no problem making a telnet connection on port 80 to the member. It can ping and tracert to the member without problem.

 

This behavior happens for any pool and member combination. Is this expected behavior? Why can I not set a pool health check and have it work correctly? I spend most of my time in LTM and am accustomed to LTM behavior.

 

thanks!

    The results should be the same between the two. Have you tried capturing the network-behavior with tcpdump, and is this GTM part of a network of iquery-connected GTMs/LTMs?

     

  • Yes. From the GTM, when I open the member server's IP address with curl, I get expected HTML from the default document.

     

  • Does the server respond as expected if you issue the curl command?

     

    From bash shell:

     

    curl http://serveripaddress
