What is the exact error that you are seeing? I can't see how a problem with that macro substitution would generate any error about 'not finding the service'.

This is unusual but based on the documentation on how to check service and host clusters, I expect this should probably work. Looking in the code it looks like macro substitution happens at the right place too... There is a problem with the resulting command in that '-e HTTP/1.1 200 OK' will be translated to '-e' with an argument of 'HTTP/1.1' and then a dangling 200 and a dangling OK to the entire command. If you want to match more than HTTP/1.1, enclose the entire 'HTTP/1.1 200 OK' in quotes.

I don't recall seeing it stated either way (should/should not). I know that you can use other macros in this way and don't believe that custom macros are special.
