Overview:
RH442VT Red Hat Enterprise System Monitoring and Performance Tuning is an advanced 4-day hands-on lab course covering system architecture, performance characteristics, monitoring, benchmarking, and network performance tuning.
Description:
Prerequisites:
Participants in RH442VT should already be familiar with Red Hat Enterprise Linux. Recommended minimum competency level is completion of the RHCE or equivalent knowledge.
Goal:
RH442VT is designed to teach the methodology of performance tuning and capacity planning for Red Hat Enterprise Linux. This class will cover: a discussion of system architecture with an emphasis on understanding the implications of system architecture on system performance, methods for testing the effects of performance adjustments (benchmarking), open source benchmarking utilities, methods for analyzing system performance and networking performance, tuning configurations for specific application loads.
Audience:
RH442VT is aimed at senior Red Hat Enterprise Linux system administrators and other IT professionals working in enterprise environments and mission-critical systems.
