With Snapt, you can easily set up health checks to ensure that your backend services are up and running before marking a load-balanced pool as online. But how do you check to see if a specific host (website) is online?
The HTTP Check URL is often set to / for the index page, or sometimes a specific page such as /status
If you want to send a Host header with it (for a specific website) you can do so by modifying the URL string. For example, to check /status on www.snapt.net you would set the following string:
/health_check.php HTTP/1.1\r\nHost:\ www.snapt.net
Step 1: Edit your group or backend
To set up the above, you’ll need to navigate to your Group or Backend Management and click on “Edit”
Step 2: Protocol Tests
Next, click on the “Protocol Tests” tab to access all the health check options with Snapt
Step 3: HTTP Check
Now, you’ll toggle on the HTTP Check button to “On”
We’ll now also set the HTTP Method to “GET” and you’ll input the string above. (Remember to change the variables)
