At what threshold does Dynatrace alert for CPU saturation?

The threshold for CPU saturation in Dynatrace is defined as when usage rises above 95% in 3 of 5 consecutive intervals. This specification ensures that the alert triggers only when the CPU usage is critically high over a sustained period, indicating a potential risk for performance degradation or service interruptions. The choice of 95% as the threshold provides a buffer to account for transient spikes in CPU usage and requires multiple intervals exceeding this level to confirm a genuine saturation risk. This approach helps in minimizing false positives, allowing teams to focus on significant performance issues that might require immediate attention.

In contrast, other options either set the threshold too low or do not require enough sustained usage to warrant an alert, which may lead to situations where actual saturation could occur without generating a timely alert. Thus, the option that specifies a 95% usage threshold over consecutive intervals is aligned with best practices for monitoring and alerting in performance management.
