QA has been awarded the Red Hat Training Reseller of the Year 2020 for the EMEA region
In order to attend any Red Hat course or exam, you will need to provide us with your unique Red Hat Network ID. Bookings will not be confirmed without this. If you do not have a Red Hat Network ID you can create one by clicking here. If you attend a virtual event, Red Hat will email you directly a Connectivity Test link one week before the course starts to ensure you have the correct access for the training.
Performance tuning and capacity planning for Red Hat Enterprise Linux
Red Hat® Enterprise Performance Tuning teaches senior Linux® system administrators about performance tuning for Red Hat Enterprise Linux.
This course discusses system architecture with an 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 Certificate of Expertise in Performance Tuning exam (EX442). This version of the course includes the exam.
Senior Linux system administrators responsible for maximizing resource utilization through performance tuning.
- 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 our online skills assessment.
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
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.
Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.
Impact on the individual
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
