Health Indicator Nodes in Policy Designer

The Properties window for a Health Indicator node contains the items that are described in the following table.

Item	Description
Primary Record check box	Specifies whether or not the node represents a primary record.
Trigger check box	Specifies whether or not changes to the record that is associated with the node will result in policy execution.

The following example illustrates how you can use the Health Indicator node with successor nodes to evaluate fields in a Health Indicator record and the associated collection of readings. Consider the following nodes and connections.

In this example, the Health Indicator node is connected to the Average Reading Value Average node and to a Greater Than or Equal Condition node.

As shown in the following image, you can use the Properties window for the Average node to select the Health Indicator node and the Reading option. When these options are selected, this node evaluates the readings that are associated with the Health Indicator record and returns the average reading value.

You can also select a field from the Health Indicator family as an input for a successor node. As shown in the following image, you can use the Properties window for the Greater Than or Equal node to select the Alert Level field in the Health Indicator family. This node, therefore, evaluates whether or not the value in the Alert Level field of the corresponding Health Indicator record is greater than or equal to 1, which would indicate that the Health Indicator record meets the Warning or Alert status criteria.
