Grafana: Template variables are not supported in alert queries : <p>Hi I want to create a simple alert in grafana to check whether there is no data for the last 5 minutes.</p>

<p>But I get an error </p>

<blockquote>

<p>Well, according to this <a href="https://github.com/grafana/grafana/issues/6230" rel="noreferrer">issue</a> templates are not supporting in grafana yet. 
I have two questions:</p>

<ol>
<li><p>What is templating?   </p></li>
<li><p>How can I avoid this error?</p></li>
</ol>
