Dynamic thresholds are based on computed values, allowing system administrators to detect performance degradation and take preemptive action.
This setting only affects the threshold profile with a dynamic monitoring mode. The threshold is automatically calculated based on the performance information, and a safety margin is added to the calculated value to avoid false alerts. The higher the safety margin, the lower the total number of alerts generated. Likewise, the lower the safety margin, the higher the total number of alerts.
The following graphs illustrate the differences between the three type of margins.
