Identifying candidate records and creating LUOWs

Log Analyzer can filter log records., filtering reduces the volume of log records that you must handle interactively or manually. As more data is included, interactive or manual analysis becomes slower and more difficult. If you have a busy IMS environment, for best results you should identify ranges and types of records that are related to the purpose of the analysis.

To identify a candidate log record and associate it with an LUOW

To identify a candidate log record and associate it with an LUOW, Log Analyzer performs the following tasks:

  1. Log Analyzer reads a record from a specified log record source.

    For more information, see Allocating-log-record-sources.

  2. Log Analyzer applies the following tests to identify candidates as applicable:
    • Skip and limit tests specify a range of records, based on the total number of records that have been read, to consider as candidates. For more information, see Skipping-and-limiting-log-records.
    • The log record code test identifies types of log records to consider as candidates. For more information, see Identifying-log-record-codes.
    • The interval test specifies a range of records, based on time or log sequence number, to consider as candidates. For more information, see Specifying-intervals.
  3. Log Analyzer retains or discards the record as follows:
    • If the record passes all applicable tests, it is retained as a candidate.
    • If the record does not pass all applicable tests, it is discarded. A discarded record is unavailable for further analysis.

  4. Log Analyzer associates the candidate record with an LUOW.

    For more information, see Creating-LUOWs.

  5. Log Analyzer applies any specified SELECT filters and identifies LUOWs of interest.

    For more information, see Selecting-log-records-and-LUOWs.
