# Checking the system logs (Linux) - Lacuna TSA

When installed on Linux, [Lacuna TSA](https://docs.lacunasoftware.com/en-us/articles/tsa) sends its logs to the systemd journal, a centralized management solution for logging
all kernel and userland processes. To view the logs, use the `journalctl` utility.

To check the Lacuna TSA logs:

```sh
journalctl -u lacuna-tsa
```

Use the `-f` flag to view logs in "follow" mode (like `tail -f`):

```sh
journalctl -u lacuna-tsa -f
```

Use the `--since` parameter to view only recent logs:

```sh
journalctl -u lacuna-tsa --since "1 min ago"
```
