The global performance indicators for \NODEB (Example 4-5) show that the health of the
system is generally good except for processor load balance, which GPA considers only
fair, and disk volume queuing, which GPA found excessive in some cases. The disk
cache performance is acceptable, although it shows potential for improvement.
Example 4-5. Global Performance Indicators for \NODEB
III. GLOBAL PERFORMANCE INDICATORS
EXCESSIVE DISPATCHING : NO INDEX LEVELS > 2 : NO
PROCESSOR LOAD BALANCE : FAIR OVER UTILIZED DISK : NO
OVER UTILIZED NODE : NO CACHE FAULT DETECTED : NO
OVER UTILIZED CPU : NO TRANSIENT PROCESSING : NO
DISK VOLUME QUEUING : YES BLOCKED REQUESTS : NO
AVERAGE CACHE HIT % :91.38% TOTAL CACHE CALL RATE: 31.00 /SEC
The global performance indicators (Example 4-6) show that the Processor Load Balance
for \NODEC is an indicator that GPA rates as poor. At 88.93%, the Average Cache Hit
% could also be improved.

The Node Characteristics section and Global Performance Indicators can (in addition to
profiling the system‟s health) point to the reasons for a system‟s poor performance.
