17.4.1 Type of log information
- Organization of this subsection
(1) System log
The system log contains log information that reports the system status and errors that occurred. This log information is output to the following log file:
For details on the output format, see the chapter explaining the log information in the manual JP1/Performance Management Reference.
- Notes on logical host use:
-
To check the control of Performance Management by cluster software, the cluster software log is required in addition to the Performance Management system log.
(2) Common message logs
The common message logs contain log information that reports the system status and errors that have occurred. The information output to these logs is more detailed than the system log information. For details on the output destination file name and file size for common message logs, see 17.4.2 Details on log information. For details on the output format, see the chapter describing the log information in the manual JP1/Performance Management Reference.
- Note:
-
The language of the common message log information is determined by the LANG environment variable set when a service is started or a command is executed, therefore, the common message log might contain character strings with different language codes.
- Notes on logical host use:
-
The common message logs are output to the shared disk when Performance Management is used on a logical host. The common message log information before and after a failover is recorded in the same log file, because the log file on the shared disk is inherited together with the system when a failover takes place.
(3) Operation status logs
The operation status logs contain the log information output by PFM - Web Console.
For details on the output destination file name and file size for operation status logs, see 17.4.2 Details on log information. For details on the output format, see the chapter describing the log information in the manual JP1/Performance Management Reference.
(4) Trace logs
The trace logs contain log information needed, when an error occurs, to investigate the cause of the error or to determine the processing time required by each process.
The trace log information is output to a log file for each Performance Management service.
- Notes on logical host use:
-
The trace logs are output to the shared disk when Performance Management is used on a logical host. The trace log information before and after a failover is recorded in the same log file, because the log file on the shared disk is inherited together with the system when a failover takes place.
