Hi, thank you for your reply, Amyas. > Something like > echo "show errors" | socat unix-connect:/tmp/hap.sock stdio I tried this command echo "show errors" | socat unix-connect:/path/to/haproxy.sock stdio and I got this messages Total events captured on [01/Jul/2013:13:50:27.032] : 731 [01/Jul/2013:13:50:26.070] frontend front (#2): invalid request src (Client IP address), session #1490245, backend <NONE> (#-1), server <NONE> (#-1) HTTP internal state 26, buffer flags 0x00909002, event #730 request length 1400 bytes, error at position 77: 00000 GET /mypath/aabbcc.cgi?param=abcdefg1234567891234567890123456789076a9 00070+ 7c483aa9\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 00092+ \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 00109+ \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 00126+ \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 00143+ \x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 .... continues '\x00' is Null ? Maybe, Haproxy is receiving invalid request that include \x00 string and Haproxy discard such requests. So 'Errors req' count is keep increasing on stats page. But I cant understand the line HTTP internal state 26, buffer flags 0x00909002, event #730 What does this mean? Thanks for your shell script, too. It's useful. Thanks. koexuka.
