Creating custom monitors on F5 GTMs

We will be implementing GSLB using F5 GTMs. The local site Load Balancers are the Citrix Netscalars. Has anyone worked with this configuration before of using the GTMs as GSLBs and Netscalars as SLBs?

 

 

 

 

I need assistance to set up custom monitors on the GTMs that monitor the health of the Virtual Servers that are set up on the local Load Balancers, that is on the Netscalars.

 

 

 

 

Any feedback is much appreciated.

 

 

 

 

Thanks
