To determine whether a requirement has been met, the requirement must be evaluated using measurable data. Generally, the types of data are:
Availability
Downtime
Outages
Incidents
In Operations Center, you can define an objective for each of these, as well as for any piece of data on which you can perform a calculation. In addition, you can use the health of an SLA as an objective to consider in another SLA. Table 5-1 summarizes objectives.
Table 5-1 Objective Types
|
Type |
Specifies… |
|---|---|
|
Availability |
A threshold minimum that availability must be equal to or above in order to be compliant within the selected interval of time. The threshold setting defaults to Critical. |
|
Downtime |
An acceptable level of total time down within the selected objective interval of time. The threshold setting defaults to Critical. |
|
Incidents |
The maximum number of incidents (of specified duration) allowed to be compliant within the selected objective interval of time. The threshold setting defaults to Critical. |
|
Outages |
The maximum number of outages (of specified duration) allowed to be compliant within the selected objective interval of time. The threshold setting defaults to Critical. |
|
Agreement |
An aggregate type calculation for agreement health that factors in health values from another Service Level Agreement, where applicable for associated elements. Select from other Service Level Agreements defined for that branch of elements. |
|
Calculation |
The Calculation objective either performs a mathematical calculation to determine if a property is compliant, or determines if a key metric based on custom properties of an element in an external data source is compliant. |
You select the type of objective when you create or edit an objective.
The common features of all objective types are:
Activation and deactivation dates
Time intervals
Threshold condition
