# Checking the system logs (Linux) - Rest PKI Core

When installed on Linux, [Rest PKI Core](https://docs.lacunasoftware.com/en-us/articles/rest-pki/core) 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 Rest PKI Core logs:

```sh
journalctl -u restpkicore
```

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

```sh
journalctl -u restpkicore -f
```

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

```sh
journalctl -u restpkicore --since "1 min ago"
```
