Nginx & Blip
Yo Nginx, ever caught the keepalive timeout tripping over 10k concurrent websockets? Letās flip it and see if we can make the server laugh at itself.
Yeah, Iāve seen that happen a few times. For 10k websockets you need to bump the worker_connections high enough and raise the send_timeout, but keep the tcp_keepalive off for the sockets you expect to stay open. If you set keepalive off, you avoid the 30āsecond drop, but youāll need to tune the max_fds on the system. In short, crank up worker_connections to something like 200k, drop keepalive for websocket workers, and let the OS handle the rest. Then the server will be laughing all the way to the logs.
Nice, so youāre just cranking up the workers, turning keepalive off, and hoping the OS will sort the FD bloat. Got itājust donāt forget to ping the logs for the chaos youāre about to unleash.
Sounds about right. Iāll keep an eye on `/var/log/nginx/access.log` for the spikes, then quietly adjust the worker_rlimit_nofile if we hit the 100k mark. No one likes a sudden FD crunch in the middle of a chat.
Cool, just watch those spikes like a hawk on a coffee break. If the FD count hits 100k, throw some magic numbers at worker_rlimit_nofile and keep the chat humming. Ready to stir the chaos when the logs go wild?
Sure thing. Iāll bump worker_rlimit_nofile to something like 200k, keep an eye on the logs, and adjust the worker_connections if the FD count starts to look like a bad party. Letās see what kind of chaos we can politely produce.
Bump that to 200k and keep the logs as your chaos radar. When the FD count starts looking like a rogue party, just tweak worker_connections again and keep the system humming. Ready to stir up some silent server drama?
Got it. Iāll bump worker_rlimit_nofile to 200k, watch the logs for any rogue spikes, and adjust worker_connections on the fly. Silent drama, here we come.
Nice, just keep the logs as your cheat sheet and watch the spike like a hawk on a caffeine buzz. When those FDs start dancing, flip worker_connections and let the server do the silent drama. Ready to hit the toggle?
Yeah, letās toggle it. Iāll keep the logs as my cheat sheet and adjust worker_connections on the fly if the FD count starts a wild dance. Silent drama, check.
Alright, fire that toggle and let the logs be your map. If the FDs start doing the salsa, hit worker_connections back to the floor. Keep me posted on the chaos.
Toggle engaged, logs are my map. Iāll watch the FD count, and if it starts salsaādancing Iāll drop worker_connections back to the floor. Keep an eye on the chaos log.
Sounds solidāwatch those logs, keep the dance floor tight, and let me know if the server starts throwing its own rave.
Got itālogs will be my radar, and Iāll keep the dance floor tight. Iāll ping you if the server starts throwing a rave.
Gotcha, keep the radar on and ping me if the server starts a fullāblown rave.
