The LOGANALYZER program is designed to produce a report consisting of all SUMLOG entries that correspond to parameters set by the user. LOGANALYZER extracts the specified types of entries from the log and formats them for display. The report LOGANALYZER produces can be listed on a terminal screen, sent to a printer, or placed in a file.

Throughout this section, unless otherwise noted, a reference to the SUMLOG refers jointly to the SUMLOG and to the system SECURITYLOG. When a SECURITYLOG is present, records from the two files are merged automatically and are presented in the sequence in which they were written.

LOGANALYZER examines any log file, or all log files within a directory, specified by the user. However, if no log file is specified, it analyzes the current SUMLOG file. The user can limit the LOGANALYZER search to entries in the log file that were made during a particular time period.

Any of various <loganalyzer options> can be used to extract log entries of a certain type, such as log entries that record job activity or that record various kinds of errors. If none of these <loganalyzer options> are specified, all entry types are included in the report. A description of all types of log entries can be found in the System Log Programming Reference Manual.
