UDP Health Monitor

This section covers the specific configuration for the UDP health monitor type.

You can send a UDP datagram to the server, then match the server’s response against the expected response data.

Default System-UDP health monitor will detect failure only when ICMP unreachable is received. It will keep the server UP until it receives ICMP unreachable for the defined UDP port. Hence it does not detect the failure:

• If the UDP health monitor request gets dropped or blackholed before reaching the server.

• If ICMP unreachable response packets are being dropped.

• If the backend UDP server does not send ICMP unreachable.

To create a new TCP health monitor, click Create button. Select the TCP option from the drop-down list of the Type field. The following screen is displayed:
