## Logs
The next place to search for details on potential errors are the log files.
On a common setup, you should search for the following files:
- `/var/log/libretime/analyzer.log` contains logs from the analyzer,
- `/var/log/libretime/api.log` contains logs from the api,
- `/var/log/libretime/legacy.log` contains logs from the legacy app,
- `/var/log/libretime/liquidsoap.log` contains logs from liquidsoap,
- `/var/log/libretime/playout.log` contains logs from playout.
The `/var/log/syslog` file contains most of the system logs combined. This log file may contain information that the application logger wasn't able to log, such as early startup errors. You can follow the logs using:
```bash
sudo tail -n 100 -f "/var/log/syslog"
# Filter the logs
sudo tail -n 100 -f "/var/log/syslog" | grep "libretime-"
```
