Can a custom HTTP monitor work with a JSON response?

Hi Aaron,

 

 

So my Devs say changing the response is not going to happen, I'm going to need to go the HEX route.

 

 

Using Wireshark, I sniffed the health check coming from the LTM on the web server, I see the response going back to the LTM self IP as 10 bytes of data representing:

 

 

{"d":true} , this equates to 7b 22 64 22 3a 74 72 75 65 7d

 

 

To make things easy for my initial test I'm just going to look for "true" which is 74727565

 

 

So I thought my receive string should be:

 

 

\x74\x72\x75\x65

 

 

But that is not matching.

 

 

I'm running :

 

BIG-IP 9.4.5 Build 1049.10 Final

 

 

Any thoughts?
