Question
An engineer is configuring the monitoring for a new application server. During the day, the CPU on the server is baselined at approximately 30% utilization. At midnight, a batch job is scheduled to run that will drive the CPU utilization up to 75% for approximately an hour. Any time the CPU utilization is at 40% or higher for longer than ten minutes, administrators will receive an alert. Which of the following is the BEST method to ensure administrators do not experience message fatigue due to false alerts?
Options
- ASet a different threshold during the batch peak time.
- BIncrease the alert time threshold to 65 minutes.
- CIncrease the alert utilization threshold to 80%.
- DManually disable monitoring during the batch job.

Why each option
To prevent message fatigue from expected high CPU utilization during a scheduled batch job, the best method is to implement dynamic alert thresholds that adjust during the peak time.
Setting a different, higher CPU utilization threshold specifically for the known batch peak time ensures that only genuinely anomalous CPU spikes above the expected batch load trigger alerts. This prevents false alarms from predictable system behavior and reduces administrator fatigue.
Increasing the alert time threshold to 65 minutes would prevent alerts during the batch job but would also delay or prevent alerts for legitimate issues that occur during normal operating hours, impeding timely incident response.
