Measurement progress
This section shows the progress of the measurement by reporting the total number of samples completed. The sample counts are further subdivided by CPU Active samples, TCB WAIT samples, and Queued samples.
| Under heading | This is displayed |
|---|---|
| Requested | The number of samples requested. A fixed percentage value of 100 percent is shown here as this number of samples represents the entire measurement. The actual number of samples performed could exceed this value if the “run to end of step” option was selected. Similarly the measurement could terminate before the indicated number of samples is done if the measured step terminates first. |
| Samples Done | The number of samples done. This is the number of samples performed so far. A percentage value and histogram indicate the ratio of samples completed to the number of requested samples. |
| CPU Active | The number of samples done in which one or more CPUs were executing instructions in the measured region. A percentage value and histogram indicate the ratio of the number of CPU Active samples to the total number of samples completed so far. |
| WAIT | The number of samples done in which all TCBs were in WAIT (non dispatchable) state. A percentage value and histogram indicate the ratio of the number of WAIT samples to the total number of samples completed so far. |
| Queued | The number of samples done in which no TCBs were CPU active and at least one TCB was dispatchable. This indicates a state in which work was not being done in the measured region because no CPU (or memory) was available. A percentage value and histogram indicates the ratio of the number of Queued samples to the total number of samples completed so far. |
