NAME

tirex-backend-manager - manages Tirex rendering backend workers

SYNOPSIS

tirex-backend-manager [OPTIONS]

OPTIONS

--help

Display help message.

-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

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

DIAGNOSTICS

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