Health monitor not working correctly

I have a health monitor setup to check web application that we have load balanced. Right now I am using this as my health monitor: Interval: 5 seconds Timeout: 16 seconds Send String: HEAD / HTTP/...

Well I would've thought in this situation the f5 monitor was still receiving a matched receive string e.g. 200, even if the web server had an issue delivering the content.

 

Could you not configure a GET request monitor instead and set the receive string as some received data from the webpage?

 

Might be better that way.
