Course Description
Red Hat Enterprise Performance Tuning (RH442)
Description
This course discusses system architecture with 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).
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
Audience
Senior Linux system administrators responsible for maximizing resource utilization through performance tuning
