Monitoring "internet"

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

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

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:

The wget.exe was downloaded online and a version is available at http://users.ugent.be/~bpuype/wget/

If you would like, I could provide a ZIP of all components. I hadn't shared it yet because I know that it is dirty and would be hard to port since I had not used variables for the paths.
