title: Alert on Azure gateway for application hosted on Azure VM
body: <p>I have to create a alert on a application which is hosted on Azure VM configured which is accessed via Azure gateway. Whenever application goes down ( any response code other than 200) have to send email to specific group of emails.</p>
  
  <p>I tried it with "backend health" active log in Configure signal logic inside alert configuration in gateway but have not got any activity log over there.</p>
