Hi i'm a student from Belgium, so my english isn't perfect but I do hope you'll understand what I'm trying to ask. I don't know if you're familiar with the plugin check_selenium? But still I'll try to explain what I'm trying to do. With Selenium I made some test cases to check my website (can I login, can I connect to it, so basically checking if I can do stuff). With the plugin check_selenium I can get results (like OK or WARNING or CRITICAL) but I don't want to use webbrowsers... so i use MOCK , like so CMD ./check_selenium.sh -c "com.example.tests.Login" -b "<a href="http://website.com">http://website.com</a>" -t "*mock" Nagios $USER1$/check_selenium -c "com.example.tests.Login" -b "<a href="http://website.com">http://website.com</a>" -t "*mock" So everything is working, but then I've put my website offline, so I normally should get a CRITICAL but i get an OK status in Nagios (or in the CMD - command line) So actually my question is, do you know how i can get this to work in Nagios without using a webbrowser? Thanks in advance Kind regards Björn <div style="visibility: hidden; left: -5000px; position: absolute; z-index: 9999; padding: 0px; margin-left: 0px; margin-top: 0px; overflow: hidden; word-wrap: break-word; color: black; font-size: 10px; text-align: left; line-height: 130%;" id="avg_ls_inline_popup"> </div>
