8.1 Notes on the collection base time

Observe the following precautions when setting the collection base time:

• Add the Option section and the SHIFTEXTRACTTIME label when you create or update the environment parameters file.

• Make adjustments to the collection base time recommended for remote monitoring by taking into account the following concept behind the recommended collection base time:

  Concept behind the collection base time

  Due to processing delay in the SAP system, the saved system log or CCMS alert information may not accurately reflect the actual time at which it arose. In this case, even when the local host is being monitored, some of the system log or CCMS alert information is not extracted, which is the same as what happens when a time delay in the SAP system (time difference between hosts) exceeds the collection base time. To avoid this problem, the default collection base time is set at 5 seconds. When a remote host is to be monitored, the effect of time delay in the SAP system must also be taken into consideration, and therefore 5 more seconds (which gives sufficient margin to accommodate an environment that meets the prerequisite of keeping a time difference between hosts to less than 1 second) is added to the collection base time, with 10 seconds being set as the recommended collection base time.
