IBM AIX system administration, part 4: Performance

Learn how to diagnose, tune, and monitor AIX for the best-possible performance


1. Understand your performance issues first

You need to understand what type of performance problems your system has by conducting an initial performance diagnosis. Based on the results, you will then tune and monitor your system’s performance accordingly.

2. Processor scheduler performance

The processor scheduler allows you to give processes priorities, set policies, and more to help improve performance.

3. Virtual Memory Manager performance

Understand how real memory is managed and how to tune memory parameters, monitor memory usage, and tune swap space settings.

4. Logical Volume Manager performance

Understand the performance of logical volumes and locally attached disk drives with respect to deciding the number and types of disk drives, and the sizes and placements of paging spaces and logical volumes on those disk drives.

5. Network performance

This topic deals with the tools and methods to monitor different communication protocols and tune them.

6. NFS performance

This topic deals with the tools and methods for Network File System (NFS) monitoring and tuning on both the server and client side.

LPAR2RRD

LPAR2RRD creates historical, future trends and nearly "real-time" CPU utilization graphs of LPAR's and shared CPU usage of IBM Power™ servers. 

It is agent less (it gets everything from the HMC/SDMC or IVM).
It supports all kinds of logical partitions: AIX, i5/OS (AS400), Linux, VIOS.


It collects complete physical and logical configuration of all servers and LPAR's.
