When you hover over the Status Light of a check it should display the message of the last result. For Instance, Fatal (RED) when hovered over should display a message of the last failure, such as, 404 URL not found. This will enable users to check the message of a check right from the dashboard instead of having to drill down and back page every time they want to navigate to dashboard in order to navigate into another check for the message.
This is something that we will consider putting into a future release. I'll keep you updated with the progress.
