A. Monitoring Configuration

A. 1 Monitoring Websites With Nagios XI

  • The Website Wizard : checking common server/site metrics
  • The Website URL Wizard : is very similar to the Website wizard. It provides a URL status (does it return a valid HTTP OK message), as well as the ability to verify a particular string is found on the page (either literally or as a regular expression).
  • The Web Transactions wizard: A more complex use case of website monitoring would be if you expect the content to be dynamic with user input and actions, and want to test that those actions complete as expected. For instance, you might test that a search box works (and what results are returned), whether the purchase and checkout process of your web store is behaving properly, or that a user can log in successfully.$
