	Table 6: Parameters for Software Service Thresholds

PARAMETER	UNIT OR TYPE	DESCRIPTION

Check_MaxResponseTime	Seconds	The maximum response time for a check. The actual response time
		for a check is compared against this threshold to determine if the
		check is running slow.

Check_Sensitivity	Percentage (%)	The percentage of samples during a set time period
		(StatisticsWindow) that must violate the Check_MaxResponseTime
		threshold to trigger an event. 0% means that one value over the
		threshold triggers the event. 100% means that every value within
		the StatisticsWindow must be over the threshold.
Note:
Note:	The StatisticsWindow is fixed and cannot be changed through the console.

Interaction of Sensitivity, StatisticsWindow, and Threshold Parameters

Resource-based settings use two parameters, Sensitivity and StatisticsWindow, in conjunction with one or more thresholds to determine when an abnormal condition exists. This design provides two benefits:

•It prevents wide variations between high and low values from skewing the results, as might be the case if values were averaged.

•It provides more control over the sensitivity of the analysis. When the value of the sensitivity parameter is 0%, one value over the threshold triggers the event. If the sensitivity parameter is 100%, every value must be over the threshold.

The following example illustrates how these parameters work:

A SoftwareElementCheck samples a parameter such as ResponseTime every 30 seconds and compares it to the threshold, MaxResponseTime. The SoftwareElementCheck records whether the value is over the threshold. At regular intervals, determined by the correlation engine, the SoftwareElementCheck compares the number of samples that violated the threshold during the most recent window interval (StatisticsWindow) to the sensitivity parameter. If the percentage of samples in violation is higher than the sensitivity parameters, a symptom is triggered.
