H Advanced WLM usage: Using
performance metrics
This appendix includes details about configuring WLM SLOs based on
metric goals and supplying performance data to WLM.
Configuring WLM for metric-based SLOs
This section includes details about configuring WLM SLOs to satisfy
metric goals.
Overview
To use WLM with metric goals, follow these basic steps:
Step 1. Identify the workloads to run on a given system.
Each workload can consist of one or more applications and multiple
users.
Step 2. For workloads with performance goals, add goal-based SLOs to your
WLM configuration by following these steps. For details on how to
specify a metric goal, see “Specifying a metric goal (optional)” on
page 470 and “Specifying a shares-per-metric allocation request
(optional)” on page 472.
a. Determine the performance metrics that are already available and
implement other metrics that are needed to ensure that the SLOs are
being met.
b. Send the metrics to WLM using one of the WLM built-in data
collectors or develop your own collector.
Data collectors supply metric data to the WLM daemon. The daemon
then uses this data to determine new resource allocations to enable
the workloads to achieve their SLOs.
You have a number of options when it comes to data collectors:
