Red Hat Certified Specialist in Performance Tuning (EX442)
The Red Hat Certified Specialist in Performance Tuning exam (EX442) assesses your proficiency in analyzing Red Hat® Enterprise Linux® and its applications’ performance using common system tools.
Additionally, the offering verifies the knowledge required to adjust the behavior of the system and apps to enhance performance using common system tools and methods.
Overview
The goal of the course is to help you get ready for the Red Hat Certified Specialist in Performance Tuning (EX442) test. Based on Red Hat Enterprise Linux 8, the course’s lessons will concentrate on a variety of common tools used to assess a Red Hat Enterprise Linux system’s performance. They will also help you develop and validate your understanding of these tools so you can use them to update and optimize a Red Hat Enterprise Linux system’s performance as well as the apps hosted on it.You can become a Red Hat Certified Specialist in Performance Tuning by passing the EX442 exam.

Our Package
Use utilities to analyze system behavior
- Use utilities such as vmstat, iostat, mpstat, sar, gnome-system-monitor, top, powertop, and others to analyze and report system and application behavior
- Use utilities such as Performance Co-Pilot (PCP) to analyze system behaviour
- Use utilities such as dmesg, dmidecode, and sosreport to profile system hardware configurations
Monitor and alter kernel behavior
- Use /proc/sys, sysctl, and /sys to examine, modify, and set kernel run-time parameters
- Configure kernel behavior by altering module parameters
Analyze system and application performance
- Analyze system and application behavior using tools such as ps, top, and Valgrind
- Configure systems to run SystemTap scripts
- Use the eBPF family of tools (e.g. syscount, gethostlatency and others) to diagnose system and application behavior
- Given multiple versions of applications that perform the same or similar tasks, choose which version of the application to run on a system based on its observed performance characteristics
Tune running systems
- Alter process priorities of both new and existing processes
- Select and configure tuned profiles
- Manage system resource usage using control groups
Tune memory utilization
- Configure systems to support alternate page sizes for applications that use large amounts of memory
Configure disk and file subsystems
- Select proper I/O scheduling algorithm
- Tune file system layout for a given use
Tune network performance
- Calculate network buffer sizes based on known quantities such as bandwidth and round-trip time
- Set system buffer sizes based on those calculations
