What is the predefined static threshold for CPU saturation alerting?

The predefined static threshold for CPU saturation alerting is set to trigger an alert if CPU usage exceeds 95% in 3 of 5 one-minute intervals. This threshold is designed to indicate significant resource strain on the system, which typically corresponds with performance degradation or application issues that may affect user experience.

Setting the threshold at 95% balances sensitivity and specificity in monitoring. If CPU usage consistently goes beyond this value across multiple short intervals, it is a strong indicator that the system may be under heavy load or might not be able to handle additional processing demands effectively. This proactive measure is essential in resource management and helps in ensuring optimal application performance.

By requiring that this level of usage is sustained over multiple intervals rather than just a single spike, Dynatrace minimizes false positives that could arise from brief, transient CPU spikes that may not impact overall performance. This approach ensures that alerts are meaningful and actionable, allowing teams to respond to genuine performance issues more effectively.
