When I hit the nginx server with a very rapid succession of requests from multiple clients, the logs will be out of order. For example, the log times would appear like this: … 18:10:11 … … 18:10:11 … … 18:10:11 … … 18:10:12 … … 18:10:11 … … 18:10:12 … … 18:10:11 … … 18:10:12 … … 18:10:12 … … 18:10:12 … Why would this be?

Time in different nginx worker processes may be slightly different as nginx only updates time once per event loop iteration (or even less frequently if timer\_resolution set). This in turn results in out-of-order times in logs you see when requests from different workers are logged. Similar effect may be also seen when using log buffering (though in this case you’ll see blocks with successive times up to log buffer size, not individual lines). Maxim D. ---

Oh I see, tricky. How is an event loop defined? Is there a value definable in nginx.conf which can shorten the event loop? Or can I just increase timer resolution to a really high number to make the log times more accurate?
