Monitoring "internet"
list Ricardo Stella
Hello, We have a request to monitor 'internet' connectivity. (When it comes from higherups...) Just pinging up the line might not be good enough as we've had issues with our providers in the recent past. So I figured ping several well known hosts out in the cloud and if all are out, then we have no 'internet'. I came out with the following. Seems to work, but figure I run it thru the list in case someone else has done this already... page internet Internet Connectivity 127.0.0.1 INTERNET # conn=ip1,ip2,ip3,ip4,ip5 TIA...

Might also want to do some HTTP checks. If your router's NAT table has problems, connection limits are hit, etc. Pretty much anything TCP based but doing an HTTP request to Google should satisfy and be easy.

Can these be combined as well? Ie do multiple http checks and go red only if all fail? TIA...

Not to my knowledge, but I've never read the man page looking for that method.

You might be able to fake it to enough satisfaction... using a combo test. You might want to put the tests on a separate page, maybe explore the NOPROPRED options. Make sure that the individual tests don't trigger alarms. set up a combo test to go red if the tests all go red, and set off an alert. Just a thought. -Alan

You can use the bbcombotest to merge the result of all your http content/status check in a single check. in bbcombotest.cfg you can put something like: internet.connect = internet.cont1 && internet.cont2 && internet.cont3 remember to change the hobbitlaunch.cfg to include the launch of bbcombotest Francesco

I have a custom EXT that we use for a test called "web" that does this. It isn't efficient coding, but it is down and dirty and it works. (For Example, I didn't use variables in a lot of places where I should to make it portable, etc.) It uses 4 components: - WebChk.bat - Run from BBNT client externals (script could be modified for BBWIN) - WebChk.lst - Is a list of websites to be checked - Wwwget.bat - Is run by WebChk.bat to test each server in WebChk.lst - wget.exe - tool that does the actual testing It produces output on the Hobbit monitor that looks like: Wed 08/05/2009 11:53:26.39 .

This isn't particularly elegant, but something like it should do what you
want:
#!/bin/bash
TESTHOSTS="www.google.com www.yahoo.com www.microsoft.com"
for N in $TESTHOSTS
do
curl -s -S -L -m 10 -o /dev/null http://$N
if [ "$?" -eq "0" ]; then
# page fetched OK
break
fi
# Ran out of hosts, must be all broken
$BB $BBDISP "status internet.web `date`
Cannot reach any common web servers, panic now!!"
exit 0
done
# found at least one working offsite server
$BB $BBDISP "status internet.web `date`
Found at least one working offsite server. The world is still there."
exit 0

You can use the bbcombotest to merge the result of all your http content/status check in a single check. in bbcombotest.cfg you can put something like: internet.connect = internet.cont1 && internet.cont2 && internet.cont3 remember to change the hobbitlaunch.cfg to include the launch of bbcombotest
Yes, you need to use bbcombotest. I would not recommend this though: internet.connect = internet.cont && internet2.cont && internet3.cont Something like this is safer... internet.connect = (internet1.cont + internet2.cont + internet3.cont) >= 2 I have used this method before to monitor major 4 web sites and seen one of them fail to respond. The other 3 were fine so I knew our internet connection was okay. Craig
