[Nagios-users] Compare HTTP Page to Saved Copy
Hi all, One one of our servers we are serving a custom 404 error page from the application code itself - what's happened is when the page breaks our nagios monitor does not see the error because the error page is being served quickly and properly. Is it possible to compare the results of a page with the previously queried page? Or would it be possible to look for a specific string and alert if the string is present?

Thanks in advance, Max try check_http with the -s option and specify that the page fetch must have a certain string or the test will fail. -h -- Hari Sekhon - Take Surveys. Earn Cash.

-m for the minimum size is also useful for a limited number of checks. I ran into this problem during a LAMP database problem resulted in the error page still being delivered. After all the webserver was still up. :) Bill On 9/20/06, Marc Powell [EMAIL PROTECTED] wrote: -Original Message- From: [EMAIL PROTECTED] [mailto:nagios-users- [EMAIL PROTECTED] On Behalf Of Max Clark Sent: Wednesday, September 20, 2006 12:08 PM To: nagios-users@lists.sourceforge.net Subject: [Nagios-users] Compare HTTP Page to Saved Copy Hi all, One one of our servers we are serving a custom 404 error page from the application code itself - what's happened is when the page breaks our nagios monitor does not see the error because the error page is being served quickly and properly.

Re: [Nagios-users] Compare HTTP Page to Saved Copy
I understand about the -s, -r and -R flags. These all look for a specific pattern. Can I look for the absense of a pattern?
