webpage contains check through nagios
 

Does any one has any idea how we can check if the contains of the webpage is the same as the previous one or is there a way in nagios to check if the webpage contains has changed. Thank you

to check if it's changed, I would write a check script that would use curl to grab the page and save it to disk (or take an MD5sum of the page data), and then pick up that file next time and compare it. The point of nagios check scripts (which are awful) is that they're just an arbitrary script with a predefined output, so just write your own script to do this.

thank you acid_kewpie, I did read that "md5 program was originally developed as part of a suite of tools intended to monitor large collections of files (for example, the contents of a Web site)" but I couldnt find any site to learn how to create MD5sum webpage, it's not like creating MD5sum iso files :( .

it is, I just don't think you understand what I'm talking about. You can pipe any data into md5sum:

for example

thanks
