Wrong (or badly interpreted) http response time with hobbit 4.2.0
list Benoit Schmid
Hello, I have monitored machines that are reporting around 3.5 seconds for the HTTP response time during the whole day (curve flat). If I do wgets, from the Solaris machine where hobbit server is installed, I get response times that is lower than 100 ms. Our old BB server reports response times that are also lower than 100 ms. Would you know why my hobbit monitor report such high response times? Thanks in advance for your answer.

Have you done a trace route from the Xymon server? Maybe that would show you something? Sorry just a suggestion from the top of my head. -----Original Message----- From: Benoit SCHMID [mailto:user-eb70faf94883@xymon.invalid] Sent: 01 September 2010 08:36 AM To: xymon at xymon.com Subject: [xymon] Wrong (or badly interpreted) http response time with hobbit 4.2.0

The only real way of tracing it is to run bbtest-net with "--debug". bbcmd bbtest-net --debug my.server.name You'll probably want to dump that output to a file... What you'll get from this looks something like this: 2010-09-23 14:50:14 About to do 3 TCP tests running 256 in parallel, abs.max 1014 2010-09-23 14:50:14 3 tests pending - 3 active tests, 0 slow tests "3 active tests" means at this point the connection is being established. For debugging your http problems, it is probably best to trim your list of tests in the bb-hosts file so you only run one test. 2010-09-23 14:50:14 Doing select with maxfd=4 We're waiting for data from the server 2010-09-23 14:50:14 select returned 1 2010-09-23 14:50:14 read 680 bytes from socket We now got 680 bytes. 2010-09-23 14:50:14 HDC IN : state=0, leftinchunk=0, len=440 2010-09-23 14:50:14 HDC OUT: state=0, leftinchunk=0, len=0 Xymon is decoding the "chunked data" sent by the HTTP server. 2010-09-23 14:50:14 TCP tests completed normally Connection has been closed Address=172.16.10.2:80, open=1, res=0, err=0, connecttime=0.001439, totaltime=0.00351 The time spent doing the connect, and the total time.
