The queue is in the kernel and controlled by the listen(2) syscall. If you're in Linux, you can inspect this with Raindrops[1] or just read the output of ss(8) or /proc/net/tcp. I don't know how to do this in non-Linux kernels. All TCP servers actually have this queue, so you can use ss(8), /proc/net/tcp or raindrops to inspect this queue in nginx, too. [1] http://raindrops.bogomips.org/ I've found this example surprisingly useful, too: http://raindrops.bogomips.org/examples/linux-tcp-listener-stats.rb -- Eric Wong _______________________________________________ Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
