11.3.1 Types of log information to be collected
- Organization of this subsection
(1) System log
The system log is used to report system statuses and errors. This log is output to the event log file.
For the output format, see the chapter explaining log information in the manual JP1/Performance Management Reference.
- Notes about logical host operation
-
In addition to the system log for Performance Management, you might need the log information for the cluster software in order to check such information as Performance Management control by the cluster software.
(2) Common message log
The common message log is used to report system statuses and errors. The log information that is output to the common message log is more detailed than the log information that is output to the system log. For details about the output destination file name for the common message log and file size, see 11.3.2 Log files and folders to check. For the output format, see the chapter explaining log information in the manual JP1/Performance Management Reference.
- Notes about logical host operation
-
When Performance Management is under logical host operation, the common message log is output to the shared disk. Because a log file on the shared disk is inherited together with the system during failover, messages are recorded in the same log file.
(3) Operation status log
The operation status log is output by PFM - Web Console. For details about the output destination file name for the operation status log and file size, see the chapter explaining troubleshooting in the JP1/Performance Management User's Guide. For the output format, see the chapter explaining log information in the manual JP1/Performance Management Reference.
(4) Trace log
The trace log is collected to investigate the process leading up to the error and to measure the time that was used for each process.
The trace log is output to the log file that each service of a Performance Management program has.
- Notes about logical host operation
-
When Performance Management is under logical host operation, the trace log is output to the shared disk. Because a log file on the shared disk is inherited together with the system during failover, trace logs are recorded in the same log file.
