check site simple

Our monitoring-plugin check_site_simple provides your monitoring system with an easy to configure but nevertheless powerful check for websites. This check monitors the content of a complete site and alarms for many anomalies like:

  • missing content
  • unwanted content
  • broken links


The program check_site_simple is a Nagios-compatible monitoring plugin to regularly test all pages of a website for their content and presentation being correct. It is meant to be used as part of monitoring systems like Icinga, Nagios (Core), op5 or Shinken.

Based on user-defined presets it can automatically detect both erroneous and deliberated website defacements in real-time and before they irritate your customers or users.


check_site_simple monitors:

  • a whole site (not just single pages) if a specific page is online

  • if this page has a predefined content like e.g. a contact phone-number, legal comments, copyright-statements.

  • if a specific content (like an outdated phone-number or a non-valid company-name) is not present

  • if broken links to either internal or external resources exist

Thanks to an integrated crawler a whole site can be monitored by just providing the start-page to the plugin.

Customer Benefits

Keeping a complex, steadily changing website free of errors manually is nearly impossible if done by human beings.

  • check_site_simple automates this process. This method is an important cornerstone for a perfect, error-free web representation of your organization.

  • User-frustrating failures can be detected in real time and before they confront the user.

  • Thanks to the prompt, clear and precise, communication of the failure, the fix can occur faster and with less effort or stress than when responding to a failure report you may get from an already frustrated customer.


Testing versions are already available, the first stable version is planned for release in August 2020. Enhancements will be added based on customer feedback.

In 2021 we are planning to release a JavaScript enhanced Version check_site_pro, which will be able to monitor complex web-applications as well.
