Where 81 and 82 tcp-ports is a tomcat, who answer "HTTP/1.1 200 OK\r\n" with some fields and close connection. And 22 is a localhost ssh server, who simply close tcp socket without answer if nginx send "GET /PingAction.do HTTP/1.0\r\n"
As i see in ngx_http_healthcheck_module.c "state 100" is a NGX_HEALTH_OK ( // Good + final states) "state 201" is a NGX_HEALTH_BAD_STATUS (// bad + final states)
But in my case all inversely - :81 and :82 are good - they answer "HTTP/1.1 200 OK\r\n" and 22 is bad - he close connection without answer
