====== Ubuntu - Services - Check logs of a service ======

===== Using systemd =====

In **systemd** logs are stored in an internal binary format (not as text files) so you need to use **journalctl** command to access them:

<code bash>
sudo journalctl -u service_name
sudo journalctl -u service_name -f
</code>

----

===== Using Upstart =====

In **upstart** logs are normal text files in the **/var/log/upstart** directory, so you can process them as usual:

<code bash>
cat /var/log/upstart/foo.log
tail -f /var/log/upstart/foo.log
