Threshold Mechanism Selection

Managing thresholds means selecting/modifying the mechanism by which SharePoint KM for PATROL sets thresholds for all parameters of the monitored components. This is done through the menu command: KM Settings > Threshold Mechanism Selection.

By default, SharePoint KM for PATROL automatically sets alert thresholds on the monitored parameters.

To set the thresholds, SharePoint KM for PATROL uses one of the following two mechanisms, best suited to the managed system:

Tuning: A standard internal PATROL mechanism, known as the Override parameters in PATROL but called Tuning in SharePoint KM for PATROL. With this mechanism, SharePoint KM for PATROL sets the thresholds of each parameter of each monitored object by setting a specially formatted variable under the /___tuning___ tree in the PATROL Agent configuration.

PCM/Event Management: PATROL for Event Management (formerly known as EventSpring) or PATROL Configuration Manager or PCM, formerly known as AgentSpring

By default, SharePoint KM for PATROL determines which of the above two mechanisms is best suited to the managed system and uses that. This is the Automatic setting in the Threshold Mechanism Selection wizard.

To see which mode is currently used for the system, or to modify the Automatic mechanism, right-click: the main SharePoint KM instance > KM Commands > KM Settings > Threshold Mechanism Selection...

•	Automatic (default): SharePoint KM for PATROL determines and uses the threshold mechanism best suited to the managed system

•	Tuning: If selected, SharePoint KM for PATROL will manage its thresholds through the standard the internal PATROL mechanism (Override parameters). Thresholds are stored in the PATROL Agent configuration under the /___tuning___ tree.

•

PCM/Event Management: if this option is selected, SharePoint KM for PATROL will manage its thresholds through the PCM or Event Management mechanism. Thresholds are stored in the PATROL Agent configuration under the /AS tree. This option requires that you set up the PATROL for Event Management KM on your PATROL Agent. PATROL for Event Management has to be enabled and preloaded.

If you use PATROL for Event Management to manage thresholds in PATROL, it is strongly recommended that you use this option in SharePoint KM for PATROL too.

In order to avoid side effects and unpredictable behavior, if you select the "PCM/Event Management" thresholds management option, SharePoint KM for PATROL will automatically remove the thresholds set through the other method. That is: if you select the "PCM/Event Management" option, SharePoint KM for PATROL will automatically remove all the thresholds stored in the /___tuning___ tree in the PATROL Agent configuration.

•	No Thresholds: SharePoint KM for PATROL will not set any thresholds on the monitored objects. You are required to set them manually.

For details on how to manually set thresholds on the parameters, please see the topic: Modify Alert Thresholds.
