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" over a specific port, ie. 8686.
The healthcheck, along with 1 VS multiple specific ports, does work; with irule applied as well on my A10's, from which I am migrating to F5. However, I cannot got a rule to allow the external monitor to work. Also, i tried just adding the irule to the VIP along with the policy. However, it doesn't work most likely because my policy has a default deny at the end- and policy executes before the irule.
Is there anyway to achieve this with a rule for the external monitor?
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.
