Overview

Red Hat® Enterprise Performance Tuning teaches senior Linux® system administrators about performance tuning for Red Hat Enterprise Linux.

This course discusses system architecture with emphasis on:

• Understanding the implications on system performance
• Methods for testing the effects of performance adjustments
• Open source benchmarking utilities
• Methods for analyzing system and networking performance
• Tuning configurations for specific application loads

This course can also help you prepare for the Red Hat Certified Specialist in Linux Performance Tuning exam (EX442).

Course content summary

• Tuning for use-case scenarios (for example, HPC, large memory, database, and file server)
• Applying tuning profiles with tuned
• Tuning virtual machines (primarily guest, but host is discussed)
• Tuning memory and caches
• Tuning CPU and memory utilization using cgroups (integrated in systemd)
• Gathering performance metrics and other data for tuning purposes

Duration

 4 days

Outcomes

1.      Impact on the organization

This course is intended to develop the skills needed to improve infrastructure performance, increase system utilization, reduce downtime, and improve responsiveness to system failures.

2.      Impact of this training

As a result of attending this course, students should be able to obtain, analyze, and interpret system performance metrics, which the business can use to increase cost effectiveness, maximize application performance, and make better decisions about investment in hardware or cloud resources.

Students should be able to demonstrate the following skills:

• Describe how key Linux subsystems work
• Interact with applications
• Determine which tuning adjustments are relevant in different situations

Prerequisites

• Red Hat Certified Engineer (RHCE®) certification or equivalent experience
• Candidates who have not earned their RHCE can confirm they have the correct skills by passing Red Hat's online skills assessment

Audience
