However, that's not an "out-of-band" health checking, as you pointed out. It's more like an integrated or "in-band" synchronous check. Rationale for that is that nginx was developed and mostly used across high load environments, so an asynchronous health check running every few minutes doesn't really help when you've got thousands requests per second per backend. We always check if a particular request has failed, and you've got means to configure the restoration logic. http://nginx.org/en/docs/http/ngx_http_upstream_module.html#server > Thanks, > Hajo > > Posted at Nginx Forum: > http://forum.nginx.org/read.php?2,238450,238450#msg-238450 > > _______________________________________________ > nginx mailing list > [email protected] > http://mailman.nginx.org/mailman/listinfo/nginx > _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
