13.3.1 Type of log information to be collected during troubleshooting

Organization of this subsection

(1) System log

The system log contains log information that reports the system status and errors that occurred. Performance Management outputs the system log to the following log file:

For details about the output formats, see the chapter that describes log information in the manual JP1/Performance Management Reference.

Notes about logical host operation

In addition to the system log for Performance Management, you need the log information for the cluster software in order to check information such as Performance Management control by the cluster software.

(2) Common message log

The common message log contains log information that reports the system status and errors that have occurred. The information output to this log is more detailed than the system log information. For details about the common message log's output destination file name and file size, see 13.3.2 Lists of log files and directories to be collected during troubleshooting. For details about the output format, see the chapter that describes log information in the manual JP1/Performance Management Reference.

Notes about logical host operation

For Performance Management under logical host operation, the common message log is output to the shared disk. Because log files on the shared disk are inherited together with the system during failover, messages continue to be recorded in the same log file.

(3) Operation status log

The operation status log is the log information that is output by PFM - Web Console. For details about the name and size of the operation status log file, see the chapter that describes error handling procedures in the JP1/Performance Management User's Guide. For details about the output format, see the chapter that describes log information in the manual JP1/Performance Management Reference.

(4) Trace log

Whenever an error occurs, the trace log contains log information that is needed to investigate the cause of the error or to determine the processing time required by each process.

The trace log is output to a log file for the particular Performance Management program service.

Notes about logical host operation

For Performance Management under logical host operation, the trace log is output to the shared disk. Because log files on the shared disk are inherited together with the system during failover, messages continue to be recorded in the same log file.
