SYNOPSIS

       tirex-backend-manager [OPTIONS]

OPTIONS

       --help

       -d, --debug
           Run in debug mode, and pass on the debug flag to workers

       -f, --foreground
           Run in foreground. E.g. when started from systemd service

       --config=DIR
           Use the DIR config directory instead of /etc/tirex.

DESCRIPTION

       The  backend  manager  starts  and  monitors  as  many backend workers as given in the configuration. The
       backend processes do the actual rendering of tiles.

       The backend manager expects each worker process to send an "alive" message in regular intervals, and will
       kill the process if it does not do so in time.

       The backend manager does not handle render requests in any way; these are read directly from a local  UDP
       socket by the individual backend processes.

       If  the backend manager receives a HUP signal, it will relay this signal to all backends, causing them to
       exit after completing their current request.  It will reload the renderer and map configuration  and  re-
       start all workers with the new configuration.

FILES

       /etc/tirex/tirex.conf
           The configuration file.

       /etc/tirex/renderer/*.conf
           Configuration files for renderers

       /etc/tirex/renderer/*/*.conf
           Map configurations

DIAGNOSTICS

       The  backend  manager  logs  to  the  daemon  syslog facility unless configured otherwise. In debug mode,
       logging is also copied to stderr.
