Define service policy general properties

Create service policies, the main building blocks of an operational policy, according to the guidelines on this page.

To view this administrative console page, click Operational policies > Service policies > New.

To create, modify, or remove service policies and transaction classes, you must have administrator or configurator administrative privileges.

Name

The name field is required and is a user defined field. The name field cannot contain the following characters: \ / , : ; " * ? < > | = + & % ' # The name defined must be unique among service policies and cannot begin with a . or a space. A space does not generate an error, but leading and trailing spaces are automatically deleted. Create meaningful service policy names that are used consistently. For example, PLATINUM, GOLD, SILVER, and BRONZE are good service policy names.

Description

The description field is complementary to the name field and is user defined. This field is optional, but in environments with multiple administrators, you must complete this field with useful information. For example, a description field for a PLATINUM policy might read, "The PLATINUM service policy is reserved for the highest priority work."

Goal type

This is a selectable field that can be one of four values:

Average response time: Indicates high priority work. This field is used with the goal value and importance to limit the time this work is kept in queue.
Percentile response time: This a percentage of requests handled in a specific period of time. This field is used with the goal percent to define the percentage of requests per seconds or milliseconds.
Discretionary: the default value for goal type. Discretionary indicates work that is not high priority and can be scheduled by the on demand router based on the existing workload in the queue.
Importance When the system is under stress, the importance value determines the application work that can best tolerate performance decrements. The higher the importance, the less tolerant that the work associated with that service policy is to performance reductions. For the PLATINUM example: select Highest as the importance. Do not set all policies to the highest level of importance, unless all policies can degrade to the same proportion when the system is overloaded.

Note: If the cell custom property disableResponseTimeGoals=true, a goal type of importance will display for service policy goal types. This goal type is utilized to establish that only the importance aspect of the service policy will be used.
