Of course it wasn't the whole script, but it still worked. :-) I then tweaked it a little to make it work better for our environment, and added a few features, like the time_total. I haven't implemented a timeout value though, although that's probably a good idea.

What you gave me was a skeleton, and after I added a bit of flesh, I ended up with something quite workable. Which worked great. Thanks :-)

Here's one that Henrik might need to address though.

If I use curl to replace the standard http test, then I can't get it to graph unless I use the NCV feature. However, I am reluctant to try this, because it might break other HTTP tests that are working well (on internal sites)

Is it OK to start graphing this using NCV, or is there a way to get the custom curl-based http test to inject the data points into the standard http graphing system?

Cheers Vernon

Heh - dude, that wasn't supposed to be the *whole* script... :)

If that one was useful, here's something that may be a bit better. I added a timeout for curl, otherwise it'll wait for a long time if the server doesn't respond. Also, this format produces a message formatted just like Xymon's internal http test, including the time taken to grab the headers. You could extract the "Seconds" line to determine if the response is a bit slow. With a bit more magic in Xymon's configs, you could even graph it...

============= cut here ============ #!/bin/sh

TESTHOST=www.google.com<http://www.google.com> TESTURL=http://$TESTHOST/

TIMEOUT=30

Grab *just* the headers, simulating Xymon's builtin http check

MESSAGE=curl -x http://ourproxy.ourdomain.com:8080 \ --proxy-anyauth -U hobbituser:hobbitpassword \ -m $TIMEOUT \ -w 'Seconds: %{time_total}\n' \ -s -S -L -I $TESTURL | $GREP -v Set-Cookie

if [ "$?" -eq "0" ]; then COLOR=green else COLOR=red fi

convert dots to commas in the hostname

MACHINE=`echo $TESTHOST | $SED -e 's/\./\,/g'

$BB $BBDISP "status $MACHINE.home $COLOR date

This script works a treat.

Thanks Vernon

Looks like your proxy requires authentication via Kerberos or NTLM or GSS-Negotiate. Dunno if Xymon can do those. Luckily the curl tool (httpp://curl.haxx.se<http://curl.haxx.se>) *can* do those... I haven't had to use them, but it should not be too hard to bang out an ext script to do the check. Something along these lines:

 #!/bin/sh
 curl -x http://ourproxy.ourdomain.com:8080 \
       --proxy-anyauth -U hobbituser:hobbitpassword \
       -s -S -L -o /dev/null http://www.google.com/
 if [ "$?" -eq "0" ]; then
   COLOR=green
   MESSAGE="Pinged Google OK"
 else
   COLOR=RED
   MESSAGE="Failed to reach Google"
 fi
 $BB $BBDISP "status www,google,com.home $COLOR `date`

$MESSAGE"

Obviously that can be expanded quite a lot... :) Drop it somewhere on your Xymon server (maybe in server/ext) and set up a block in server/etc/hobbitlaunch.cfg to fire it off as often as you want. You may need to give the full path for curl, which is probably /usr/bin/curl.
