Quantification
Each detail line reports the number of active CPU samples for an indicated CPU state. This is also expressed as a percentage of the total number of active CPU samples.
The CPU states are not all mutually exclusive. Overlaps in the counts reported in different detail lines will occur.
| Under Heading | This is Displayed |
|---|---|
| Storage key n | The number of active CPU samples in the indicated storage protect key. A value of 8 indicates user (application) key. Other values usually indicate execution is in a system routine. |
| Problem state | The number of active CPU samples in problem state. This is the usual state for application programs. |
| Supervisor state | The number of active CPU samples in supervisor state. This mode allows execution of privileged instructions. This typically indicates execution in an operating system routine. |
| Execution in SVC | The number of active CPU samples while executing in SVC (Supervisor Call) modules. |
| Execution in real mode | The number of active CPU samples in real mode. There are no normal operating conditions under which this mode can occur. The value should always be zero indicating execution in virtual mode. |
| Primary-space mode | The number of active CPU samples in which the ASC (Address- Space Control) bits indicate execution in primary-space mode. |
| Access-register mode | The number of active CPU samples in which the ASC (Address- Space Control) bits indicate execution in Access-register (AR) mode. |
| Secondary-space mode | The number of active CPU samples in which the ASC (Address-Space Control) bits indicate execution in secondary-space mode. |
| Home-space mode | The number of active CPU samples in which the ASC (Address- Space Control) bits indicate execution in home-space mode. |
| Execution on processor n | The number of active CPU samples in which instructions were being executed by the indicated processor. Processors in a multi-CPU system are numbered 0,1,2,3 ... etc. Specialty processors such as zAAP are identified to the right of the processor percentage. |
| In private storage ABOVE | The number of active CPU samples in which instructions were located in private storage above the 16MB boundary. |
| In private storage BELOW | The number of active CPU samples in which instructions were located in private storage below the 16MB boundary. |
| In common storage ABOVE | The number of active CPU samples in which instructions were located in common storage above the 16MB boundary. |
| In common storage BELOW | The number of active CPU samples in which instructions were located in common storage below the 16MB boundary. |
| Execution in AMODE 24 | The number of active CPU samples in which instructions were being executed in AMODE 24. |
| Execution in AMODE 31 | The number of active CPU samples in which instructions were being executed in AMODE 31. |
| Execution in AMODE 64 | The number of active CPU samples in which instructions were being executed in AMODE 64. |
