If more than one host logs data, typically tapes of the logs are brought to a single host for consolidation, whether in SMF-style records or not. Similarly, much of the data are pre-processed, by MXG, into a single database of staging data, whether the data were in SMF-style records or not. IT Service Vision treats all data that MXG puts in this data base as if the data had been written on SMF-style records and collected by SMF.

If you have data on CICS or DB2 transactions, on multiple hosts or even a single host, you may not want to collect it (for space or time reason.)

In that case, you can process the data directly from the logs to the reduction level of one or more PDBs, one time or more each day by using views. This will be described later in this document.

Or, you can reduce the data directly from the logs to the reduction (non-detail) levels of on or move PDBs. This is described in the %CMEXTDET macro in the reference documentation for IT Service Vision.
