When does Dynatrace alert about a high number of network errors?

The correct answer indicates that Dynatrace will alert you when network errors reach a threshold of exceeding 3% with a minimum of 10 connection failures per minute. This approach provides a clear and actionable way to measure network health, ensuring that alerts are generated only when the error rate is significantly high and not just due to isolated incidents.

The rationale behind this specific threshold is that it balances sensitivity with practicality. A threshold of 3% signifies a notable problem in network connectivity that could substantially affect user experience or application performance. Furthermore, requiring a minimum of 10 failures within a minute ensures that sporadic single events do not trigger unnecessary alerts, which would lead to alert fatigue and potentially diminish the value of the monitoring solution.

In contrast, other options do not align as effectively with common networking practices. They may reflect thresholds that are too low or insufficiently detailed, making them less practical for real-world applications.
