Promotional still for WLM and Performance Readouts

Course lead

Priya Nair

Builds performance literacy modules that bridge WLM policy language and operator readouts.

Description

Performance tuning belongs to specialists, yet operators need to recognize when goals drift and what evidence to collect. This course connects service class semantics with real console indicators. You practice readouts that explain contention without blaming applications unfairly. Labs stay clear of tuning knobs that require change boards; instead you focus on observation, logging, and escalation quality.

What is included

  • WLM policy walkthrough using anonymized enterprise examples
  • Labs on correlating delayed jobs with service class shifts
  • Script for requesting a tuning consult with complete context
  • Threshold worksheet operators can own without root-cause authority
  • Case study on misleading green dashboards during paging pressure

Outcomes

  1. Produce a performance readout consumable in a cross-team review.
  2. Identify when a symptom is likely WLM-related versus I/O-related.
  3. Escalate with logs that shorten specialist investigation time.

Participant questions

No. Labs rely on standard monitors and included extracts.

Experience notes

“The service class narrative finally helped us explain delays to apps without pointing fingers.”

— Eun K. , Operations analyst · survey

“I wanted more on I/O tuning, but the escalation script alone saved us hours last month.”
