Any reason why you are not using Iquery to get the ltm object status.

Simply put the https monitor for the ltm pool. Iquery mesh between the GTM & LTM. Add the LTM as bigip server. The LTM will update the GTM about the VS status.

 

Unless there's some real good reason.

 

For the troubleshooting. From the GTM, perform these basic functions,

 

  1. ping <server-ip>
  2. telnet <server-ip> <port>
  3. curl -kv http://<server-ip>:<port>/refdata-st1

 

See what response you get for them. Keep us posted.
