Note that links to the issues and PRs on the original repository (matrix-org/synapse) should not be replaced with ones on the forked one (element-hq/synapse) as those are not available on the latter, where the issues and PRs with the same number as matrix-org/synapse are "reserved" to avoid conflicts between those repositories. For reasoning of such complexity (including the reason why trasferring the original repository to element-hq/synapse was avoided), see: https://github.com/element-hq/synapse/issues/6#issuecomment-1861116896 Signed-off-by: Suguru Hirahara <acioustick@noreply.codeberg.org>

Maintenance and Troubleshooting
How to see the current status of your services
You can check the status of your services by using systemctl status. Example:
sudo systemctl status matrix-synapse
● matrix-synapse.service - Synapse server
Loaded: loaded (/etc/systemd/system/matrix-synapse.service; enabled; vendor preset: enabled)
Active: active (running) since Sun 2024-01-14 09:13:06 UTC; 1h 31min ago
Docker containers that the playbook configures are supervised by systemd and their logs are configured to go to systemd-journald.
To prevent double-logging, Docker logging is disabled by explicitly passing --log-driver=none to all containers. Due to this, you cannot view logs using docker logs.
To view systemd-journald logs using journalctl, run a command like this:
sudo journalctl -fu matrix-synapse
Increasing Synapse logging
Because the Synapse Matrix server is originally very chatty when it comes to logging, we intentionally reduce its logging level from INFO to WARNING.
If you'd like to debug an issue or report a Synapse bug to the developers, it'd be better if you temporarily increasing the logging level to INFO.
Example configuration (inventory/host_vars/matrix.example.com/vars.yml):
matrix_synapse_log_level: "INFO"
matrix_synapse_storage_sql_log_level: "INFO"
matrix_synapse_root_log_level: "INFO"
Re-run the playbook after making these configuration changes.
Remove unused Docker data
You can free some disk space from Docker, see docker system prune for more information.
