Hi,
I'm not sure if this is the right place to report this issue, but perhaps someone has already run across it and has some insights...
Basically, the "nginx_upstream_check_module" (versions 0.1.9 and 0.3.0) doesn't seem to be working with nginx 1.7 greater than 1.7.6.
Upstreams don't get pinged for status, and calling check_status directive results in the following error:
"
http upstream check module can not find any check server, make sure you've added the check servers
"
It looks like the module is not initialized correctly, e.g. it does not receive a list of upstream servers.
I also opened a github issue for the module itself -- https://github.com/yaoweibin/nginx_upstream_check_module/issues/58.
Best regards,
Jakub Wroblewski
