Duration: 1 Day
The Red Hat Enterprise Performance Tuning Exam (IES) is a performance-based test of the skills covered in Red Hat Enterprise Performance Tuning (RH442). To enroll in this exam, you must hold a current Red Hat Certified Engineer (RHCE) certification.
What You Will Learn
Audience
- Experienced Linux system administrators responsible for maximizing resource utilization through performance tuning
- RHCEs interested in earning a Red Hat Certification of Expertise or an RHCA certification
Prerequistes
- Current RHCE certification at the time the exam is taken
- Real-world system administration experience is an important aspect of exam preparation
Course Outline
You should be able to:
- Use utilities such as vmstat, iostat, mpstat, sar, gnome-system-monitor, top, powertop, and others to analyze and report system and application behavior
- Configure systems to provide performance metrics using utilities such as RRDtool
- Use the Pluggable Authentication Modules (PAM) mechanism to implement restrictions on critical system resources
- Configure graphical SNMP client utilities such as MRTG, RRDtool, etc.
- Use the Pluggable Authentication Modules (PAM) mechanism to implement restrictions on critical system resources
- Use /proc/sys, sysctl, and /sys to examine and modify and set kernel run-time parameters
- Use utilities such as dmesg, dmidecode, x86info, and sosreport to profile system hardware configurations
- Analyze system and application behavior using tools, including ps, strace, top, and Valgrind
- Configure systems to run SystemTap scripts
- Alter process priorities of both new and existing processes
- Configure systems to support alternate page sizes for applications that use large amounts of memory
- 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
- Configure disk subsystems for optimal performance using mechanisms such as swap partition placement, I/O scheduling algorithm selection, and file system layout
- Configure kernel behavior by altering module parameters
- Calculate network buffer sizes based on known quantities such as bandwidth and round-trip time and set system buffer sizes based on those calculations
- Select and configure tuned profiles.
- Manage system resource usage using control groups
As with all Red Hat performance-based exams, configurations must persist after reboot without intervention.
