XenApp Session Page File Size (Alert)

Comtrade.Citrix.XenApp.Rule.SessionPageFileSizeConsecutive (Rule)

Monitors the page file size of a session.

Knowledge Base article:

Summary

Alert is triggered only when page file size is above threshold for specified number of consecutive samples (NumberOfSamples parameter).

Configuration

The following configuration parameters are customizable:

IntervalSeconds	The recurring interval of time in seconds in which the alert rule is started (the default value is set to 300 seconds). In general this parameter should not be changed. To achieve alert to be triggered after different time than default, update NumberOfSamples parameter.
Threshold	The threshold value for page file size in MB. Default value is 2000.
NumberOfSamples	Number of consecutive samples considered before generating an alert. Minimum value for this parameter is 2. For example, set this parameter to 3 if alert should be generated only when file page size is above threshold for 3 consecutive monitoring intervals.
ConsolidationInterval	This value must be always set based on NumberOfSamples and IntervalSeconds parameters. Please see the formula below.

Formula for ConsolidationInterval:

ConsolidationInterval = ((NumberOfSamples - 1) * IntervalSeconds ) * 1.1

Example for monitor to generate alert only when monitored value is above threshold for 20 minutes (4 consecutive samples):

IntervalSeconds = 300 (5 minutes) NumberOfSamples = 4 ( 20 minutes / 5 minutes = 4) ConsolidationInterval = ((4 - 1) * 300) * 1.1 = 990
