Specify the Hostname (or IP address), IP Destination Port and IP Protocol of the LWHB
server. Typically the IP Source Port should be 0, allowing the unit to use the next available
port.
The Lightweight Heartbeat client remembers the IP address of the server so that it does not
need to perform a DNS lookup for each heartbeat. The DNS Cache Period specifies how
long the server IP address is remembered before performing another DNS lookup. If a
heartbeat should fail to contact the server, then a DNS lookup is forced for the next attempt.
The Heartbeat Period defines how often to send a LWHB message.
A server response is optional, so the server may just hangup (TCP). For TCP, the client
detects the hangup and ends the heartbeat, but for UDP, the LWHB client wait for Response
Timeout seconds for any possible response.
If the server does respond, the response is a single string of comma-separated messages or
commands.
