Requirements

The plugin relies on Selenium Grid and SeInterpreter. It expects a Selenium Grid hub which can run on a remote host or on localhost. Furthermore, it requires Java RE installed and the JAR file of SeInterpreter available on localhost.

Installation

The installation and configuration of the plugin is very simple.

1. Download, unzip and copy the script check_website_by_selenium.sh to your Nagios plugin location (see USER2 in the Nagios documentation)
2. Adapt the path to both, JRE and SeInterpreter according to your needs, see section Default options in the script

The Plugin can be used with Nagios/Thruk/Icinga.
