       This manual page documents briefly the lava-coordinator daemon.

       lava-coordinator is a daemon to manage Multi-Node communications
       between LAVA devices under test.

           Overrides the default log level of INFO. Available options, in
           increasing order of verbosity, are: ERROR, WARNING, INFO, DEBUG.

           The system-wide configuration file to control the behaviour of
           lava-coordinator. A LAVA NodeDispatcher installed on the same
           machine as the coordinator will use the same file. NodeDispatchers
           on remote machines need their own copy of this file, modified so
           that the coordinator_hostname field is the hostname or IP address
           of the machine running the coordinator.


       The LAVA Coordinator needs to be in lock-step with compatible versions
       of the LAVA NodeDispatcher (part of lava-dispatcher / lava-server) but
       the coordinator is a singleton and there can be multiple dispatchers,
       none of which need to be on the same machine as the coordinator.

       Additionally, when a dispatcher is installed on a machine other than
       the machine running the coordinator, a copy of the LAVA Coordinator
       conffile needs to be copied to that machine and modified to indicate
       the hostname or IP address of the LAVA Coordinator for that dispatcher.
       Typically, this can be done with tools like salt, puppet, chef etc.

       Therefore, lava-coordinator does not depend on the rest of LAVA and the
       setup of the coordinator is at the discretion of the LAVA lab
       administrator. As long as there is one Coordinator and all dispatchers
       have a working address for a coordinator, all should be well.

       If a lab contains more than one Coordinator, it is recommended that
       each coordinator uses a different port. This is mandatory if more than
       one coordinator is installed on a single machine.

       LAVA Coordinator is lightweight and has minimal dependencies,
       installing on virtualised hardware is not expected to be a problem.
