Advanced Tools for AIX Performance Analysis Classroom Live Redwood City, CA January 07, 2019

Description

Develop the skills to use kernel traces, trace based utilities, and svmon to measure and analyze CPU, memory, and I/O performance issues on IBM systems running AIX. Reinforce each lecture during extensive hands-on lab exercises and get practical experience applicable to their performance management requirements.

Audience

The audience for this training includes AIX technical support personnel, performance benchmark personnel, and AIX system administrators.

• Use the kernel trace facilities to analyze CPU performance issues
• Describe causes and impacts of high context switching rates
• Identify what causes a thread to be blocked and later woken up
• Explain the relationship between the output of svmon -G, svmon -P, and svmon -S
• Calculate the amount of memory in use on the system
• Explain the relationship between svmon, vmstat, and ipcs output
• Categorize the memory in use on the system by segment type
• Identify which processes are using the most memory or paging space
• Describe the characteristics of asynchronous I/O, synchronous I/O, direct I/O, and concurrent I/O
• Identify if the expected type of I/O is being executed
• Tune asynchronous I/O
