<h1 id="looking-to-the-logs">Looking to the logs</h1>
<p>While using openHAB, we will need to look the the logs generated by the software.</p>
<p>Two log files are going to interest us.</p>
<p>To find them:</p>
<ul>
<li>open the finder,</li>
<li>navigate to your home folder,</li>
<li>navigate inside the openHAB folder,</li>
<li>navigate inside the userdata folder,</li>
<li>navigate inside the logs folder</li>
</ul>
<!-- ![](images/log-folders.png) -->
<ul>
<li>Inside the logs folder, double-click on the <code class="highlighter-rouge">openhab.log</code> file. The file will be displayed inside the console application.</li>
</ul>
<!-- ![](images/log-screen.png) -->
<blockquote>
<p>The console will display the messages as soon as they will be logged. Keep this window somewhere in order to take a look inside when it is needed.</p>
<p>We will use it to check the Z-Wave dialogs.</p>
<p>A “clean” startup looks this way in the log file :</p>
