If you have a need to both collect performance data and also have the measurement of the same performance data impact the total health of the monitored object, you need both a rule and a monitor. Why? Again, monitors don’t collect anything – they just evaluate the data live and reflect back what is found in terms of health state changes. Rules collect data but have no impact on health state.
