For your current example.

 

For Pool 1, You need to create three monitors.

 

  1. Default Pool monitor that will monitor node-1 and node-2.
  2. Monitor to monitor node-3 and it's port.
  3. Monitor to monitor node-4 and it's port.

2 and 3 can be achieved by creating Alias address and Alias port in the monitor. Alias address will contain address and port of node-3 & node-4. Other request response string same as for monitor created for pool2.

 

Now apply that monitor 1 i.e default to the pool.

 

Apply monitor 2 & 3 to the pool member (click node1:port, Configuration Advanced, Health Monitors- Member Specific, Select monitors 2 & 3, Availability requirement atleast 1)

 

Repeat for node2:port

 

So, if both monitors 2 & 3 fail i.e node 3 and 4 fail then Pool member will fail and the VS 1 should go down.

 

I have not tested this but hope this works. Let me know your result
