This section suggests one way in which to implement WLM. This is only a suggestion and may not be appropriate in all situations.

  1. Implement a static configuration with usage goals.

    A static implementation has a set number of workloads that are active at all times. One way to implement such a configuration is to set up usage goals for the workloads.

    Evaluate the system and workload performance under this configuration from one to seven days and fine-tune the configuration.

  2. Implement a configuration with metric goals for the workloads.

    Again, evaluate the system and workload performance under the configuration from one to seven days and fine-tune the configuration.

  3. If applicable, implement a time-based configuration with goals.

    Use the condition and exception keywords to indicate times when SLOs are active. These keywords are explained in the section “Specifying when the SLO is active (optional)”.

Set mincpu to 0 and maxcpu to 100. Monitor the system for one to two weeks to determine:

  • How often are the goals met?

  • Do the workloads ever reach the mincpu or maxcpu values?

  • Do the mincpu and maxcpu values need adjusting?

For more information on mincpu and maxcpu, see “Specifying the lower and upper bound requests on CPU resources (optional)”.
