I had somehow never heard of it. I use a unix socket for unicorn (should I not?) so I had to make a copy of linux-tcp-listener-stats.rb to support that. Now I'm able to get stats for my unicorn master. However, there seems to be some problem getting stats on TCP sockets: $ ruby linux-tcp-listener-stats.rb 127.0.0.1:9000 address active queued linux-tcp-listener-stats.rb:42:in `tcp_listener_stats': Connection refused - sendmsg (Errno::ECONNREFUSED) from linux-tcp-listener-stats.rb:42 $ grep 0100007F:2328 /proc/net/tcp 1: 0100007F:2328 00000000:0000 0A 00000000:00000000 00:00000000 00000000 500 0 25307310 1 ffff880134471700 3000 0 0 2 -1 None of the TCP sockets I know to exist seem to work - they all fail with that error. Any ideas? -Greg _______________________________________________ Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
