Policy for Exchanges Using "Media Health Indicator" Example

This example policy generates alerts for exchanges where the media health indicator is Evaluate.

Exchange alert policies differ from policies for other library system components in that the severity of the policy is irrelevant. Because exchanges are discrete events, exchange alert policies always generate alerts when the policy criteria are met, regardless of policy severity.

Policy entity: Exchanges

Policy severity: Because this is an exchange alert, the policy severity is irrelevant. In this case, the severity is "Informative," but the results would be the same for all severity levels: alerts are generated for all exchanges involving media with EVALUATE health.

Policy criteria: Media Health Indicator is EVALUATE.

Time/Events	Evaluation	Result
13:13:17, Day 1 The policy is created and enabled. Media Z health is EVALUATE.	The policy is evaluated for all exchanges and no match is found.	No alert is generated.
14:43:09, Day 1 An exchange occurs for Media Z, whose health is EVALUATE.	The policy is evaluated for all exchanges and matched for Media Z.	An alert is generated for Media Z and emails sent to the defined recipients.
07:20:24, Day 1 Another exchange occurs for Media Z, whose health is still EVALUATE.	The policy is evaluated for all exchanges and matched for Media Z.	A new alert is generated for Media Z and emails sent to the defined recipients.
15:05:19, Day 2 Another exchange occurs for Media Z, whose health is still EVALUATE.	The policy is evaluated for all exchanges and matched for Media Z.	A new alert is generated for Media Z and emails sent to the defined recipients.
