You can select for the IP sensors individual thresholds and warning states. As shown in the screenshot below, you see the temperature sensor with the ID 201002 named as "Temperature Sensor Server Room”. The temperature sensor’s value ("Current Value") is measured at 26.5 ° C.
On the graphical bar you see a triangle. This triangle is in the “High warning level” since the measured value exceeds the “High warning level” which is defined at 20.5 ° C.
Of course you can choose your individual sensor thresholds and warning values for your concrete requirements. Just enter these values with your keyboard or take the cursor of your mouse.
