Having an issue getting HTTP Advanced sensor to work on some websites



I created a HTTP Advanced sensor to monitor to make sure a website stays up. Website site is https://driver.ats-inc.com and I am putting in https://driver.ats-inc.com into the URL and selecting Set sensor to error if keyword is missing with 'Please log in.' and its coming back with String not found.

Hello mattsy,

Thank you very much for your contact.

The issue is caused due to the redirection of the web sites to "https://driver.ats-inc.com/#/login". You could change the keyword to "ATS Driver" which is the title before being redirected.

If this does not suit your requirements, please change the Result Handling options within the sensor's Settings tab and check the created log files for further information. Most of the web sites content is being provided via JavaScript which is not supported by the sensor, so checking the title is the most suitable way to check the sites availability.

Best regards,
