title: How to use variables in Grafana-Alert-Message? especially for the value of "threshold"
body: <p>is here any body knows how to use system variables in Grafana-Alert-Message? especially for the value of &quot;threshold&quot;</p>
  <p>As we know, we can configure the alert triggers on &quot;grafana panel&quot;, according to the predefined values of last() or avg() etc/, but how can we pass those variables in &quot;Alert Notification Message&quot;? like the parameters used below:</p>
  <pre><code>Metrics Name is: ${__name__}
  AlertName is: ${alertname}
  Instance is: ${instance}
  Job is: ${job}
  HostName is: ${hostname}
  Handler is: ${handler}
  </code></pre>
  <p>i am wondering if i could put some descriptions in the notification like: The value of ${var_1} exceeded the threshold of ${var_threshold}.</p>
  <p>Thanks in advance.</p>
