Health Results
A client can receive health messages from a Gocator sensor by connecting to the Health TCP channel
(port 3194).
The Data channel (port 3196) and the Health channel can be connected at the same time. The sensor
accepts multiple connections on each port. For more information on the Data channel, see Data Results
on page 387.
Messages that are received on the Data and Health channels use a common structure, called Gocator
DataProtocol (GDP). Each GDP message consists of a 6-byte header, containing size and control fields,
followed by a variable-length, message-specific content section. The structure of the GDPmessage is
defined below.
