Hi Rick, I gave this a run this afternoon. In my case, I just set up an haproxy unit in one model and a Nagios server in another, and connected the haproxy:reverseproxy to the nagios:website. Everything worked exactly as expected. One comment about the user interface: the "juju relate" for the client side seems a bit redundant, since "juju add-relation" could easily work out which type of relation it was by looking at the form of the provided identifier. If we pass a URI to an offered relation in another model, it could use a cross-model relation, and if we just use normal service:relation-id format, it could use a normal relation. Anyway, just wanted to say it's great to see some progress on this, because it solves some real operational problems for us. I can't wait for the cross-controller, reverse-direction, highly-scalable version which will allow us to obsolete the glue scripts needed to connect our Nagios server to all our deployed NRPE units! :-) -- Regards, Paul Gear Site Reliability Engineer Canonical - Information Systems
