Linux Training : Red Hat Enterprise Linux Systems Administration<br>(System Monitoring and Performance Management)

The Red Hat Enterprise Linux Systems Administration: System Monitoring and Performance Management course introduces participants to performance management principles, monitoring utilities / tools, and analysis for the RHEL 6 Operating Environment. The course includes a review of RHEL 6 subsystems, along with the utilities provided to monitor system efficiency including sar and the *stat family of tools. In each area of discussion, emphasis will be placed on writing tools for monitoring and analysis. These tools will include Korn shell scripts, Perl procedures, and C language programs.

This course is the equivalent to Red Hat course 442.

Systems: Red Hat Enterprise Linux Version 6 (all update levels)

Linux Training Prerequisites

It is assumed that the participant has successfully completed the Red Hat System Administration I (RH 124) and Red Hat System Administration II (RH 134) courses, or has equivalent system time as a user and a working systems administrator.

Linux Training Course duration

This course normally requires three (3) days, approximately 60% lecture, and 40% lab time.

Linux Training Course Objectives

On completion of this course, a systems administrator should be able to:

Describe performance management fundamentals
Use the RHEL 6 and third-party tools to analyze performance
Write tools in various languages
Use RHEL 6 performance data extensions
View and set kernel-based tuning parameters
Monitor and report on process and thread activity
Modify CPU scheduling and virtual memory operations
Enable dynamic monitoring via SystemTap in all major areas
