Get the most out of your systems with our Classroom and Online RH442 | EX442 Training at WebAsha Technologies. Aligned with Red Hat Enterprise Linux 10, it develops the hands-on performance-analysis and tuning skills validated by the performance-based EX442 exam.
Training Overview:
The RH442 EX442 training focuses on analyzing and tuning RHEL performance: measuring CPU, memory, storage I/O and network behaviour, interpreting monitoring data, applying tuning profiles and kernel tunables, and tuning systems for real workloads and bottlenecks. Real labs prepare you to tune systems under exam conditions.
Intended Audience:
This course is ideal for senior Linux administrators, SREs, performance and infrastructure engineers who need to diagnose and resolve performance issues on Red Hat Enterprise Linux.
Topics Covered:
-
Performance Analysis Methodology: Approach performance problems systematically.
-
CPU & Scheduling: Analyze CPU utilisation and tune process scheduling.
-
Memory Management: Understand and tune memory, swap and caching.
-
Storage & I/O: Analyze and tune disk I/O, schedulers and filesystems.
-
Network Performance: Diagnose and tune network throughput and latency.
-
Tuning Profiles (tuned): Apply and customise tuned profiles for workloads.
-
Kernel Tunables (sysctl): Adjust kernel parameters for performance.
-
Workload Tuning: Tune systems for databases, web and virtual workloads.
Requirements:
Learners should have RHCE-level Linux administration skills. Online participants need a stable internet connection and a laptop/desktop for the live RHEL 10 labs, which are essential for EX442 skills.
Pre-Requisites:
Red Hat recommends RHCSA and RHCE-level Linux administration experience before RH442/EX442.
Career Benefits:
EX442-certified engineers who can tune performance are in strong demand. In India, packages typically range from ₹6 LPA to ₹26+ LPA in roles such as Senior Linux Administrator, Performance Engineer and SRE, with a path toward the RHCA.
