rates the relative performance of the node’s subsystems with scores ranging from 0 to
100 percent.
The performance scores for \NODEA (Example 4-8) clearly show how poorly some of
the subsystems are performing, mainly because of the node’s severe memory
shortage.
Example 4-8. System Performance Indicators for \NODEA
IV. SYSTEM PERFORMANCE SCORE
1. CPU SUBSYSTEM 1%
2. MEMORY SUBSYSTEM 1%
3. DISK CACHE SUBSYSTEM 83%
4. DISK VOLUME SUBSYSTEM 9%
5. SYSTEM RECOVERY PERFORMANCE 52%
*6 WEIGHTED ANALYSIS SYSTEM SCORE 1%
* Average Score rated: BEST = 100, WORST = 0.
In the case of \NODEB (Example 4-9) the scores indicate that the disk volume
subsystem has the greatest potential for improvement.
Example 4-9. System Performance Indicators for \NODEB
IV. SYSTEM PERFORMANCE SCORE
1. CPU SUBSYSTEM 88%
2. MEMORY SUBSYSTEM 100%
3. DISK CACHE SUBSYSTEM 91%
4. DISK VOLUME SUBSYSTEM 26%
5. SYSTEM RECOVERY PERFORMANCE 75%
*6. WEIGHTED ANALYSIS SYSTEM SCORE 76%
* Average Score rated: BEST = 100, WORST = 0.
Example 4-10 shows that for \NODEC, on the other hand, the most potential for
improvement is in the System Recovery Performance, the Disk Volume Subsystem,
and the CPU Subsystem.

IV. SYSTEM PERFORMANCE SCORE
1. CPU SUBSYSTEM : 76%
2. MEMORY SUBSYSTEM : 92%
3. DISK CACHE SUBSYSTEM : 88%
4. DISK VOLUME SUBSYSTEM : 68%
5. SYSTEM RECOVERY PERFORMANCE : 52%
* 6. WEIGHTED ANALYSIS SYSTEM SCORE : 75%
