APM CPU Metrics count and AIX Server CPU count show different results.

CA Application Performance Management Agent (APM / Wily / Introscope) INTROSCOPE


 Platform monitors enable the Java agent to report system metrics, including CPU statistics, to the Enterprise Manager. Platform monitors are included with the Introscope agent installers.

 Platform monitors on all operating systems except Windows Server and AIX are automatically enabled in a Java agent installation. Windows Server and AIX platform monitors require minimal configuration to work.

On AIX 5.3, why does the Introscope Agent report twice the number of CPUs than the actual number of physical processors?


CA APM 10.x AIX 5.3


 This is expected behavior, as AIX 5.3 enables simultaneous multi-threading (SMT) by default. SMT allows one physical processor to be configured as two logical processors.
