Use this command to start data collection. You can start data collection in continuous mode or sampling mode.
In continuous mode, all 4 of the collectors are run one after the other to gather summary performance data, and then one collector is run for a specified interval of time to collect detailed performance data.
In sampling mode, both summary and detailed performance data are gathered in turn by one or more specified collectors. These collectors are run one after the other in a specified order for specified collection intervals.
Requirements and Restrictions
The TPF system must be above 1052 state and cannot be cycling.

Additional Information
Sampling mode has less of an impact on system performance than does continuous mode because of the sampling mode gaps. Larger gaps lessen the impact on system performance even more.
Examples
Data collection is started in continuous mode in the following example. Data is continuously collected for 300 5-second intervals.
+--------------------------------------------------------------------------------+ |User: ZMEAS SS05 | | | |System: MEAS0001I 11.58.40 STARTING | +--------------------------------------------------------------------------------+
Data collection is started in sampling mode in the following example. The system collector runs first, followed by the program collector, the file collector, and the message collector. Each collector is run, in turn, for 5 seconds of the 23-second sampling period. This 23-second sampling period repeats for 30 minutes.
+--------------------------------------------------------------------------------+ |User: ZMEAS I/SPFM/3023/05 | | | |System: MEAS0001I 11.58.40 STARTING | +--------------------------------------------------------------------------------+
Data collection is started in sampling mode in the following example. The system collector runs first for 10 seconds and then the message collector runs for 15 seconds. The total sampling period lasts for 28 seconds, which implies a 3-second gap after the collection cycle. The sampling period repeats for 30 minutes. After data collection samples an event, 9999 events are skipped before another event is sampled.
