It should work for any RMW (though I tested it for Zenoh only).</p> <p>After building the workspace, run it like this:</p> <pre><code class="lang-bash">ros2 run ros2topic_hz ros2topic_hz --topic &lt;topic_name&gt; [--topic-type &lt;topic_type&gt;] [--interval ] </code></pre> <p><small>1 post - 1 participant</small></p> <p><a href="https://discourse.openrobotics.org/t/simple-c-node-to-get-more-accurate-topic-frequency/57741">Read full topic</a></p>
