Like other target types, the key performance indicators of the service targets can also be measured and are represented as metrics. Modeling, measuring, and monitoring the key performance indicators of a business function as metrics of the service target is a key precursor to managing the service-levels of the associated business service. OEM Grid Control provides four categories of metrics for measuring and monitoring the key performance indicators of the service targets.
As discussed in earlier chapters, availability is used to denote the status of the business function that is abstracted by a service target. The possible values for the availability metric include the following:
UP
DOWN
BLACKOUT
METRIC COLLECTION ERROR
AGENT UNREACHABLE
PENDING
UNKNOWN
These are computed based on the key system components or key service tests from key beacons based on the availability algorithm AND or OR.
