All of the advisors follow the same reporting format, which is a single page XML file you can
use to quickly assess conditions by visually inspecting the report and looking at the
descriptive icons, as shown in Figure B-1.

Java Performance Advisor)
The XML reports generated by all of the advisors are interactive. If a problem is detected,
three pieces of information are shared with the user.
1. What is this?
This section explains why a particular topic was monitored, and provides a definition of the
performance metric or setting.
2. Why is it Important?
This report entry explains why the topic is relevant and how it impacts performance.
3. How do I modify?
Instructions for addressing the problem are listed in this section.
VIOS Performance Advisor
The VIOS Performance Advisor provides guidance about various aspects of VIOS, including:
CPU
Shared processing pool
Memory
Fibre Channel performance
Disk I/O subsystem
Shared Ethernet adapter
The output is presented on a single page, and copies of the report can be saved, making it
easy to document the settings and performance of VIOS over time. The goal of the advisor is
for you to be able to self-assess the health of your VIOS and act to attain
optimal performance.
