Dynamic Baselines

The SevOne performance management solution establishes baselines for all performance indicators by “learning" the normal utilization or performance levels. SevOne can build a baseline value for the normal utilization level for any period of the day and alert you when your performance levels exceed your historical norms. Threshold-based alerts can be set for when actual performance levels deviate from their historical norms. Since normal performance levels can change throughout the day, the baselines values are dynamic, based on 10 week moving averages of historical data for that specific period of time. These baselines can be calculated and monitored in increments as small as 5 minutes or as large as an hour. The benefit of a dynamic baseline is to eliminate false positives and improve the accuracy of performance monitoring based on historical views of what is normal behavior.

SevOne provides two types of thresholds for alerting - static and dynamic. Static thresholds can trigger when a server reaches 70% utilization or if a router drops more than a specified number of packets for a given period of time. They can also trigger when response times fail to meet their desired targets for IP SLA tests, HTTP response, DNS response, TCP response and any other third party, time stamped performance metric. Dynamic thresholds are specific to time periods within the 24 hour day, and can be set above and below the baseline value so that you receive alerts if network traffic spikes or if traffic levels drop dramatically. Within Dynamic Thresholds, SevOne can alert to standard deviation criteria to provide higher confidence in alerts that demonstrate a more significant deviation from historical performance monitoring levels.
