Description

This article describes how to configure a reverse monitoring for a service on NetScaler.

Configuring Reverse Monitoring - Background

A reverse monitor marks a service as DOWN if the probe criteria are satisfied and UP if they are not satisfied. For example, if you want a backup service to receive traffic only when the primary service is DOWN, you can bind a reverse monitor to the secondary service but configure it to probe the primary service.

The NetScaler appliance supports the following reverse monitors:

  • HTTP
  • ICMP
  • TCP (from release 11.1 build 49.x)
