A broker is automatically configured to save log output to a set of rolling log files. The log files are located in a directory identified by the instance name of the associated broker (see Appendix A, Distribution-Specific Locations of Message Queue Data):
For a broker whose life cycle is controlled by the Application Server, the log files are located in a subdirectory of the domain directory for the domain for which the broker was started:
The log files are simple text files. The system maintains nine backup files named as follows, from earliest to latest:
log.txt log_1.txt log_2.txt … log_9.txt
By default, the log files are rolled over once a week. You can change this rollover interval, or the location or names of the log files, by setting appropriate configuration properties:
See Table 17–11 for further information on these properties.
