When Log Analyzer is producing LUOW-based reports and identifies a candidate log record, Log Analyzer associates the candidate with an LUOW.

An LUOW is a set of related log records that represent all of the actions that were performed to accomplish a particular activity, such as executing a transaction, in the IMS environment. Log Analyzer associates log records with an LUOW by matching the values of certain fields in those records.

During LUOW processing, Log Analyzer determines whether each LUOW (and its associated records) should be retained as an LUOW of interest or discarded.

For more information about how LUOWs are created, see Selecting log records and LUOWs.

If producing a single-record report, Log Analyzer bypasses LUOW processing.
