Red Hat Enterprise Linux Performance Tuning (RH442) Training in United States of America

Build advanced skills in Red Hat Enterprise Linux performance tuning, analysis, and capacity planning.

Red Hat Enterprise Linux Performance Tuning (RH442) is an advanced training course designed to provide experienced Linux system administrators with a systematic methodology for measuring, analyzing, and optimizing system performance.

The course explores system architecture with particular attention to its impact on performance. Participants work with performance metrics, open-source benchmarking utilities, networking optimization, and tuning configurations for different server workloads and use cases. The training focuses not only on identifying performance issues but also on interpreting collected data and applying appropriate optimizations according to workload requirements.

This course is based on Red Hat Enterprise Linux 10.

Benefits for Organizations

RH442 helps organizations improve infrastructure performance by equipping system administrators with the skills required to identify and address system performance issues effectively.

Applying structured performance analysis and tuning practices can help organizations:

• Improve overall infrastructure performance.
• Increase utilization of existing system resources.
• Reduce system downtime.
• Respond more effectively to performance problems and system failures.

These capabilities are particularly valuable when optimizing resource utilization across physical, virtualized, and cloud-based infrastructure.

Benefits for Participants

After completing the course, participants should be able to collect, analyze, and interpret system performance metrics and use the resulting information to make informed optimization decisions.

Participants will develop skills that can help them:

• Evaluate system resource utilization.
• Identify performance bottlenecks.
• Apply tuning techniques to improve application performance.
• Maximize the effective use of available system resources.
• Support better decisions regarding hardware and cloud resource investments.
• Improve cost efficiency through more effective infrastructure utilization.

Recommended Next Certification Exam

After completing RH442, participants may continue with:

Red Hat Certified Specialist in Performance Tuning Exam (EX442)

Participants are recommended to have:

• Red Hat Certified System Administrator (EX200) certification or equivalent Red Hat Enterprise Linux knowledge and hands-on experience,
• Completion of Red Hat's free skills assessment to determine whether the course matches their current level of expertise.

RH442 is particularly suitable for professionals responsible for maximizing infrastructure resource utilization and optimizing system performance across different deployment environments, including:

• Platform engineers,
• Cloud administrators,
• Linux system administrators.

During the training, participants will:

• Collect system performance metrics and benchmarking data.
• Analyze and tune system performance for specific resource and workload scenarios.
• Apply appropriate tuning profiles using TuneD.
• Optimize RHEL guests running in virtualized environments.
• Profile and analyze system events and activities.
• Manage resource limits and utilization through systemd-integrated control groups.
