Alerting for Netscaler VIP

How do I create an alert for the VIP on netscaler.

I have created the rule to monitor the netscaler using snmp and I can see the VIPs under “Load Balancer”. What I am trying to do is,

  1. Alert when any of the real servers under the VIP goes down.
  2. Alert when the entire VIP goes down.

Anyone here has got a macro for the same?

Any help will be appreciated.
