Web downtime monitor

witnessmenow

Hi guys,

I'm looking for some kind of a tool to monitor when a network loses internet connectivity, it doesn't need to do anything with the information other than storing it locally. Someone was saying that the internet goes down regualraly in my dad office and I'd like to see how bad it is (leave a the program running for a week)

Anyone know of an application that will do this for me

I was thinking of writing a shell script for it, but i dont any machine in the office is a linux one (I would have done it using a combo of ping | grep >> test.txt) could it be implemented in CMD batch file?

Would a ping -t work? You could write the results to a txt file easily and should show you loss.

There is a handy freeware app for this.

I'm not too sure if that'll write it's own txt report though.

Can't you just redirect the output of PING to a text file? eg: ping www.boards.ie -t > results.txt

Let me dig out a Windoze machine to test that....

It will work but I can't see an option to add a time stamp to the output so you'd have no idea from the above command when the link went down just that it did.

Checked out the link from chin_grin, does exactly what you need, I have bookmarked that one for myself. Thanks.

It seems like a great little program, and you can log to a file but there seems to be a problem. It doesn't seem to persist if it fails, I was pinging boards, bulled out my ethernet cable at it gave up pinging after it failed once.

Thanks for the suggestion though

chin_grin

Just did the same. Yeah, got a "hardware error" then when I plugged the cable back in (thinking it would resume) it didn't.

Ah well!

I'd say try a batch file? "ping -t"?

I have a batch file that will work, sort of it has its issues too though

cd C:\Users\brian
echo Ping Test > results.txt
:Loop
echo %time% >> results.txt
ping www.boards.ie >> results.txt
goto Loop

Problem is though, when it cant find boards.ie it goes like the clappers!! See attached file. (sending mulitple pings every second)

I need to make it sleep, will look into it during lunch

Switch Description
-a Resolves IP addresses to hostnames
-i Lets you set Time To Live (TTL)
-l Lets you set the packet size
-n Lets you set the number of echo requests
(the default is 4)
-t Pings the computer you specified until you
type Control-C (While ping is running, typing
Control-Break inserts statistics.)
-w Lets you set the number of milliseconds to wait
before each reply times out

Would you be able to use a switch? By a glance I wouldn't have a notion!

Stick 'sleep 1' in the loop somewhere so it'll always wait a second between each iteration.

[edit] Also, change it to 'ping -n 1' too.

You could try mtr or set up nagios on your machine to monitor it?
MTR will only give you stats at the end of the week of how long each link was up, whereas nagios will tell you whatever you want it to tell you(probably overkill for this scenario)
