Create "Health Monitor" rule for Existing Local Traffic Policy

I have a working, existing policy, which allows specific service ports to 1 VS. However, I also need to allow an external HTTP a Health Check [rule], which would respond with a string and a "200 OK" ...

    I checked BIG-IP v16.0 and iRules are still the way to go if you want to send a custom HTTP response. There is no functionality to be able to do this from a local traffic policy.

Thanks for your response. None of the redacted rules will catch 8686.

 

Port 8686 is the port that the external monitor uses to monitor the VS. So, the monitor connects, on 8686, performs a GET and I need a Policy which will return a string, with 200 OK.

 

Also, creating an HTTP_REQUEST rule is not an option. I do see HTTP_METHOD and since the monitor is sending a GET this could work if with "at request time". In the action, or , "Do the following when the traffic is matched" section. I need to understand the syntax I am to configure to return a string with 200 OK.

 

I want a policy to perform this function. If it is not possible, creating a [policy] rule 8686 and setting ignore makes sense in conjunction with placing an iRule, for the health monitor, on the VS.

 

I read that a tcl: variable could be set in order to use iRule functionality in the Local traffic Policy as well.

 

I hope my goals are more clear to you now.
