<h2>Debugging lqos_scheduler<a class="headerlink" href="#debugging-lqos-scheduler" title="Permalink to this heading"></a></h2>
<p>In the background, lqos_scheduler runs scheduler.py, which in turn runs LibreQoS.py</p>
<p>One-time runs of these individual components can be very helpful for debugging and to make sure everything is correctly configured.</p>
<p>First, stop lqos_scheduler</p>
<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>sudo<span class="w"> </span>systemctl<span class="w"> </span>stop<span class="w"> </span>lqos_scheduler
</pre></div>
</div>
<p>For one-time runs of LibreQoS.py, use</p>
<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>sudo<span class="w"> </span>./LibreQoS.py
</pre></div>
</div>
<ul class="simple">
<li><p>To use the debug mode with more verbose output, use:</p></li>
</ul>
<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>sudo<span class="w"> </span>./LibreQoS.py<span class="w"> </span>--debug
</pre></div>
</div>
<p>To confirm that lqos_scheduler (scheduler.py) is able to work correctly, run:</p>
<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>sudo<span class="w"> </span>python3<span class="w"> </span>scheduler.py
</pre></div>
</div>
<p>Once you have any errors eliminated, restart lqos_scheduler with</p>
<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>sudo<span class="w"> </span>systemctl<span class="w"> </span>start<span class="w"> </span>lqos_scheduler
