Baselining and Alerts in Cisco PVM
Cisco PVM provides you with the ability to proactively monitor the network using thresholds. You can identify problems and trouble spots
before they impact users. Threshold violations result in alerts, which can be viewed in the Alert Viewer. Cisco PVM provides you with the
ability to set two kinds of thresholds.
Fixed Thresholds – These thresholds accept absolute values for severity levels and the statistic of choice, the crossing of which results in
alerts.
Dynamic Thresholds – These thresholds accept percentages. When a dynamic threshold is set, Cisco PVM starts baselining the selected
statistic by creating a moving average and calculating the standard deviation for incoming data points. The standard deviation and moving
average combine to account for traffic patterns and also for expected spikes in traffic. Cisco PVM uses these values to calculate a rising and
falling threshold level (Baseline + Standard deviation = Rising Threshold, Baseline - Standard deviation = Falling Threshold) and issues alerts
when the incoming values are the specified percentage over the threshold levels.
To create a threshold, click Add in the Thresholds menu item of the Setup tab. The following screen is displayed.
