Service Policy

In addition to the resources that constitute a service, each service specifies a policy that infers a service viability (its service health) based on the collective status of its resources. The role of the service policy is to create an accurate representation of the service health that is based on health of the resources that comprise the service. The objective is to ensure that the health indicated by the service model in CA Spectrum reflects the performance of service. Selecting or creating the appropriate service policy is essential to ensure that service health is accurately represented in CA Spectrum.

A policy specifies a single attribute to monitor for the collective set of service resources. The policy is comprised of two basic components, the Attribute Map and the Rule Set. The Attribute Map
associates resource attribute values to service health values. The
Rule Set defines the health of the service by giving a set of resource health values.
A service can also include one or more resource monitors instead of a single policy. Each resource monitor can use its own policy extending the monitoring capability of the service.
A number of policies are shipped with CA Spectrum Service Manager which represent common resource monitoring patterns. If applicable, you can use these policies to familiarize yourself with the creation of custom policies. The use of custom policies can be necessary to verify the accuracy of health that is represented by the service model.
