RH442 Red Hat Enterprise System Monitoring and Performance Tuning
Goal:
RH442 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. Where possible, emphasis will be placed on using tools that are provided as part of Red Hat Enterprise Linux and Red Hat Network.
Audience:
RH442 is aimed at senior Red Hat Enterprise Linux system administrators and other IT professionals working in enterprise environments and mission-critical systems.
Prerequisites:
Participants in RH442 should already be familiar with Red Hat Enterprise Linux. Recommended minimum competency level is completion of the RHCE or equivalent knowledge.

Important Note:
For developers or candidates with a strong programming background in C, we offer RHD236 Red Hat Enterprise Linux Kernal Internals. The focus of this course is gaining a better overall understanding of how the Linux kernel works. Attendees in this course will examine the actual code that comprises the Linux kernel. This course contains numerous challenging lab exercises that require the ability to both read and write C code.
