Real User Monitoring tools help proactively identify problems before they become critical by monitoring thresholds. There is a threshold and an SOA threshold. For example, it starts to go yellow, and if it becomes red, the system will crash. When it starts to become yellow (Threshold Approaching), we have to resolve it. This is the same case where we'll know what happened before it's too late. So we can make an early decision to prevent it, maybe by kicking some users off the system before it crashes.
