Monitoring Apache web server status

[Paul Mancillas]

I need to be able to monitor the status of an Apache web server from a remote system on the Internet. Does anyone know of a way to check if a web site is up or down by using a query (like HTTP GET command) from another system on the Internet? Can I use a Perl or shell script to do this? If the web site goes down then I need the script to send an email to page me? Thank you for your help.

Hello Paul,

Piece of cake. Just use wget like that:

wget YOUR_URL_GOES_HERE >/dev/null 2>&1 && echo "OK"

Just change the "echo OK" command for whatever you need, like a program that sends you mail or something.

Regards,
Paga

Oops...

Or even better, you may want to send email when your server is NOT OK. :)

wget YOUR_URL_GOES_HERE >/dev/null 2>&1 || echo "Webserver is down" | mail youraddress@goeshere.com

Does anyone know if "wget" is available for HP-UX?
