12. User Interfaces 35 A CPU Load Index value of 10 for a group means that the average CPU load for all CPU sensors of this group currently is at 10 of the highest ever measured CPU usage value of that group For response times usually the historic maximums are much higher than the average value E g for pings ina LAN a normal time might be 2 10ms while a maximum of several hundred Milliseconds is not unusual This is the reason that most Response Time Index readings are usually between 10 and 20 How does it work e During the normal network monitoring process PRTG records the highest value ever measured for each sensor e The current measured value is weighted with this boundary values to compute an index value for a sensor between 0 and 100 For each device the index values for CPU load sensors traffic sensors and sensors that measure response times are combined e For each groups the index values of all devices are combined Keep in mind that changing the sensor setup i e the number and types of sensors will also inevitably change the index values because the numerical base for the calculation changes This means that value before and after a configuration change may not be comparable at all The same applies to situations where one or more sensors can not be monitored e g when a probe is disconnected Box with Alerts Every time a new event occurs while you are logged into the web interface of PRTG Network Monitor
