Defining SLOs
Chapter 5186
Defining SLOs
Use slo structures to specify your service-level objectives and assign
priorities to those objectives.
You define slo structures for a host partition or based on the workload
groups you defined in the prm structure. For information on specifying
the prm structure, see “Defining the PRM components (optional)” on
page 149.
Defining an slo structure consists of the following tasks:
• Specifying the SLO name (required)
• Specifying the priority (required)
• Specifying the workload group to which the SLO applies (optional)
• Specifying the lower and upper bound requests on CPU resources
(optional)
• Specifying a goal (optional)
• Specifying a fixed or additive allocation of CPU shares (optional)
• Specifying a shares-per-metric allocation request (optional)
• Specifying when the SLO is active (optional)
An slo structure can take one of two forms. Both forms require a
priority. The first form may or may not have a goal.
slo slo_name {
pri = priority;
[ entity = PRM group group_name; ]
[ mincpu = lower_bound_request; ]
[ maxcpu = upper_bound_request; ]
[ goal = goal_expression; ]
[ condition = condition_expression; ]
[ exception = exception_expression; ]
}
The second form of an slo structure uses the cpushares statement. This
statement cannot be used with a goal statement.
slo slo_name {
pri = priority;
[ entity = PRM group group_name; ]
