NGINX module reporting 0 time to access.log

December 01, 2014 10:09PM
Hey all,

We've written a module to connect NGINX / OpenResty with ZMQ endpoints (https://github.com/neloe/ngx_zmq), but all requests through the module report a 0.000 time back to access.log, making it impossible to determine which of our subsystems is the problem area in terms of latency. Is there a flag or callback somewhere that needs to be implemented in order to report this time properly?

Semi-related to the issue above... We're seeing an odd behaviour where we get idle CPUs but 2s-120s oscillating latencies. Flame graphs reveal we're spending most of our time in nginx's http handler and epoll waiting, but I'm not sure what else I expect them to say.

Any help or advice is greatly appreciated.

Thanks!
