Is there any documentation for VDI XenDesktop 7.1 without APM

Is there any documentation for XenDesktop 7.1 with LTM that does not have the APM?

 

A lot of the documentation points to the setup with APM, but we do not have that. We have the DDC and the Secure Gateways. We are just looking for any documentation on how to monitor how many desktops are published with any particular DDC.

 

I know there is a check to see if the publisher is working.

 

My whole idea is to see if a certain site has 140 active sessions, I would like it to move it over to another site via the load balancer. We have the LTM & GTM in our environment. I was wondering if there were any well known iApp Templates or Irules we could use for this.
