When does Dynatrace alert regarding high network utilization?

Dynatrace alerts regarding high network utilization typically begin when traffic utilization crosses a significant threshold, which is commonly set at 90%. This threshold is chosen because it indicates that the network is under considerable strain, likely affecting performance and potentially leading to packet loss, latency, or other disruptions in service quality. Monitoring at this level allows organizations to proactively address congestion before it impacts user experience or application performance.

The selection of 90% as the alerting threshold is consistent with established best practices in network management, where maintaining performance levels below this figure is critical for ensuring smooth operations. Setting the threshold lower, such as at 70% or 85%, may lead to alerts being issued too frequently, potentially leading to alert fatigue, where notifications become less actionable. Likewise, waiting until utilization exceeds 95% could be too late to mitigate performance impacts effectively.
