[Xymon] FW: http ping in a script

[Knox, Wesley]

This worked like a charm. Thank you kind sir. KISS is always the best solution. Thanks for saving me from my own over-thinking!

It would likely be easier to substitute 'curl -I' for the ping in your script, then process the output from the curl command.

Thanks,

So I have a script which monitors 3 ip's behind an l2l tunnel and I only get a red face if ALL 3 are unreachable. The script looks like so:

#!/bin/sh

BBHTAG=VPN          # What we put in bb-hosts to trigger this test
COLUMN=$BBHTAG        # Name of the column, often same as tag in bb-hosts

$BBHOME/bin/bbhostgrep $BBHTAG | while read L
do
   set $L # To get one line of output from bbhostgrep

   HOSTIP="$1"
   MACHINEDOTS="$2"
   MACHINE=`echo $2 | $SED -e's/\./,/g'`

   COLOR=green
   MSG="$BBHTAG status for host $MACHINEDOTS"

#... do the test, perhaps modify COLOR and MSG

COLOR=green             # By default, everything is OK
MSG="All is OK"
HOSTS="172.200.129.226 172.34.55.66 172.202.94.226"
PINGCNT=3     # number of times to ping
STATUS="bad"

for host in $HOSTS
do
    ping -c $PINGCNT $host
    if [[ $? == 0 ]]
    then
        STATUS="ok"
    fi
done
if [ $STATUS != "ok" ];then
    COLOR="red"
    MSG="Tunnel is down"
fi
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR `date`

${MSG}
   "
Done
****************************************************************************************************
The script works fine form most of my tunnels, but some clients don't allow ping on the network, and on top of that an even better check would be to hit 3 diff sites that are on those ips for the host for example http://172.66.11.33/hello/imhere.gif. Is there a simple way to motify the script above to use these full http host rather than the singular ip?  I see in hobbitlaunch.cfg the bbnet entry which is responsible for the http test looks like this

[bbnet]
        ENVFILE /home/hobbit/server/etc/hobbitserver.cfg
        NEEDS hobbit
        CMD bbtest-net --report --ping --checkresponse --timeout=30
        LOGFILE $BBSERVERLOGS/bb-network.log
        INTERVAL 5m

Do I need to make mine look somewhat like this so I can use the bbtest-net cmd within my script instead of just ping? I know its kind of a long wordy question and much help to anyone who can offer insight.
