Setting global utilization limits
The default global utilization limits, which are applied in the absence of more specific limits, are:
◦ CPU utilization may not exceed 70% of allocation for more than 0
minutes.
◦ Memory utilization may not exceed 100% of allocation more than 0%
of the time.
Adding a utilization limit

2. For each metric for which you wish to add a utilization limit:
a. Select the type of limit you wish to place, the utilization metric the limit applies to and the
utilization value above which the limit applies. For a Percent of Time Limit, enter the
percent of time the utilization value may be exceeded and a comment describing the
limit. For a Sustained Minutes limit, enter the duration in minutes the utilization may be
exceeded, and a comment describing the limit.

Setting workload utilization limits
Utilization limits allow you to set service level objectives for workloads based on overall system
utilization. For any given workload, you can specify one or more service level objectives. The limit
acts as an indicator for what the desired maximum usage would be. This limit can be applied to
selected workloads on existing systems viewable from the Matrix OE Visualization tab.
The workload utilization limits apply only to the selected workload(s).
