[openresty-en] multiple lua-resty-upstream-healthcheck upstreams

rpaprocki

Hello!

I would like to specify multiple nginx server{} blocks, each with its
own upstream checked by the resty upstream healthcheck module. i see the
following comment in the example:

-- Just call hc.spawn_checker() for more times here if you have
-- more upstream groups to monitor. One call for one upstream group.

Do we, however, need to specify additional shm dicts for each upstream,
or will one shm suffice for multiple upstream definitions?

You can share the same shm zone among multiple upstream {} blocks
because the keys have the upstream name prefixed.

I'll make it clear in the documentation :) Thanks for bringing this
into my attention!
