title: AWS - EC2, is there application health check like ELB?
body: <p>[Edited]</p>
  
  <p>How do I check my application(web server)'s health check in EC2?</p>
  
  <p>Say, I have 2 ec2 instances, ec2-webApp1 and ec2-webApp2. Both of them are listening to port 80.
  webApp1 is connected with ELB which I can use "health check" whether if the application is running or not.
  <a href="http://webApp1.internal.ip/myApp:80" rel="nofollow noreferrer">http://webApp1.internal.ip/myApp:80</a> ==> send a Get request, and the application returns 200 OK response.
  I put this URL as health check URL in ELB setting.</p>
  
  <p>whereas ec2-webApp2 is not connected with ELB and I want to set up monitoring alarm so when the app is not running, I can get the notification.</p>
  
  <p>In the ec2-webApp2 instance, I checked "Status Checks" tab / "Monitoring" tab -> "Create Alarm," but I couldn't find like one in ELB status check where I can configure custom URL to tell AWS how to check if myApp is running.</p>
  
  <p>I wonder how other people setup application monitoring.</p>
  
  <p>TIA</p>
