If you're using Linux, you can use Raindrops[1] to interrogate via inet_diag or parse /proc/net/{tcp,unix} yourself. You can run Raindrops separate/standalone script: http://git.bogomips.org/cgit/raindrops.git/tree/examples/linux-tcp-listener-stats.rb Or use it as middleware (see webpage): http://raindrops.bogomips.org/ git clone git://git.bogomips.org/raindrops -- 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Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
