# 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](https://wiki.archlinux.org/title/Systemd) and their logs are configured to go to [systemd-journald](https://wiki.archlinux.org/title/Systemd/Journal).
|
|
|
|
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](https://man.archlinux.org/man/journalctl.1), run a command like this:
|
|
|
|
```sh
|
|
sudo journalctl -fu matrix-synapse
|
|
```
|
|
|
|
|
|
## Increasing Synapse logging
|
|
|
|
Because the [Synapse](https://github.com/matrix-org/synapse) Matrix server is originally very chatty when it comes to logging, we intentionally reduce its [logging level](https://docs.python.org/3/library/logging.html#logging-levels) from `INFO` to `WARNING`.
|
|
|
|
If you'd like to debug an issue or [report a Synapse bug](https://github.com/matrix-org/synapse/issues/new/choose) to the developers, it'd be better if you temporarily increasing the logging level to `INFO`.
|
|
|
|
Example configuration (`inventory/host_vars/matrix.DOMAIN/vars.yml`):
|
|
|
|
```yaml
|
|
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](https://docs.docker.com/engine/reference/commandline/system_prune/) for more information.
|
|
```bash
|
|
ansible-playbook -i inventory/hosts setup.yml --tags=run-docker-prune
|
|
```
