Red Hat Enterprise Linux Systems Administration

			System Monitoring Performance Management


				COURSE DESCRIPTION

	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 RHEL5 Operating 
	Environment. The course includes a review of RHEL5 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 5 (all update levels)



				COURSE OBJECTIVES

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

	•	Describe performance management fundamentals 
	•	Use the RHEL5 and third-party tools to analyze performance
	•	Write tools in various languages
	•	Use RHEL5 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
