The Out of Tolerance Temperature Trends Insight is tied directly to the Temperature Beacon. When the temperature of one of your BlueCats thermometers falls out of the acceptable range, an Insight will be generated.
By clicking Learn More, you can view more information about all of the out-of-tolerance temperatures. The accompanying image shows two red dots which is your threshold (also displayed below the image), and then a gray line indicating where the temperature was recorded. You can also click the dropdown to show what the temperature was when the information was recorded.
