INFO: Health Check URL does not Work using a 3rd party load balancer

Show/Hide Article Tools

Description
When trying to configure a 3rd party load balancer, the URL for health check does not work.

Symptoms
When trying to check whether the appliance is responsive or not using the http://Vital.Security.Health.Check URL, you get a 502 Bad Gateway message (also when trying to surf this URL with a browser such as Firefox or Internet Explorer).

Cause
The URL is case sensitive and should be http://Vital.Security.Health.Check.
However, when using a browser the URL is reformatted to: http://Vital.security.health.check which fails, causing the return of a 502 Bad Gateway error message.

Solution
Try telnetting to the IP of the scanner in port 8080 and type the following:
GET http://Vital.Security.Health.Check HTTP/1.0
This should return a 403 forbidden or 407 authentication required.
After you receive one of these replies above, you should set the health check URL in the load balancer as follows: http://Vital.Security.Health.Check
