Logging Sample Configuration File

Below is a sample logging configuration file. This file can be tweaked to control how your homeserver will output logs. The value of the log_config option in your homeserver config should be the path to this file.

To apply changes made to this file, send Synapse a SIGHUP signal (or, if using systemd, run systemctl reload on the Synapse service).

Note that a default logging configuration (shown below) is created automatically alongside the homeserver config when following the installation instructions. It should be named <SERVERNAME>.log.config by default.
