GMS is an acronym for Group Management Service
The Group Management Service (GMS) a MQTT Client, is an application that manages the by-group
topic ucl/by-group/. It acts as a lookup entity that provides protocol controllers
or other MQTT clients information about the interactions between
groups, endpoints, and supported commands. It does not handle the topics that are
used to execute group commands, for example
ucl/by-group/<group-id>/<Command>, which is done by protocol controllers.
The GMS application does not persist any collected information. Instead, it collects and publishes its data over the MQTT Framework.
Protocol controllers can run without the GMS application, which results in limited functionality.
For installing please refer to the general installation method in Getting started.
The best way to run the GMS is using the Systemd service that is installed with the Debian installer. For more information, see the Unify Framework User guide.
Alternatively, the GMS may be run by executing uic-gms. It is possible to
configure the MQTT server, database path, through command line options. For more
details, run uic-gms --help.
