CPU modes
This graph is omitted for DDF measurements.
| Under Heading | This is Displayed |
|---|---|
| CPU Active | The number of observations of CPU active TCBs. This number represents 100 percent of the data upon which the graph is based and is used as the divisor to compute the percentages shown in other lines in the graph. This value is different from the “samples” value reported in the “Overall CPU Activity” graph because multiple concurrent CPU active TCBs (multiple CPUs executing concurrently) are counted separately here. This quantification represents the overall consumption of CPU time. |
| Supv Mode | The number of observations of CPU active TCBs while the system was in supervisor (privileged) mode (usually system routines). |
| Prob Mode | The number of observations of CPU active TCBs while the system was in problem state. Applications normally execute in problem state. |
| In SVC | The number of observations of CPU active TCBs while the system was executing in an SVC (supervisor call) routine. |
| AMODE 24 | The number of observations of CPU active TCBs while the system was in 24 bit addressing mode. |
| AMODE 31 | The number of observations of CPU active TCBs while the system was in 31 bit addressing mode. |
| AMODE 64 | The number of observations of CPU active TCBs while the system was in 64 bit addressing mode. |
| User Key | The number of observations of CPU active TCBs while the system was in user storage key (key 8). |
| System Key | The number of observations of CPU active TCBs while the system was in a system storage protection key. |
