10.3.1 Types of log information to be collected
- Organization of this subsection
(1) System log
The system log contains log information that reports the system status and errors that have occurred. This log information is output to the following file:
- In Windows
-
Event log file
- In UNIX
-
syslog 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 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 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 name and size of the file to which the common message log information is output, see 10.3.2 Log files and directories to check. 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
-
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 the log information that is output by PFM - Web Console. For details about the name and size of the file to which the operation status log information is output, see the chapter that describes troubleshooting in the JP1/Performance Management User's Guide. For details about the output formats, see the chapter that describes log information in the manual JP1/Performance Management Reference.
(4) Trace log
The trace log is the log information that is collected in order to investigate the details of an error and determine the processing time required by each process when an error occurs. The trace log is output to a log file for each service of the Performance Management programs.
- 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.
(5) Agent log
The agent log is the log information for processing related to record collection. It is output by PFM - RM for Platform. In the event of an error, the agent log is collected in order to obtain detailed information about the processing. For details about the agent log, see 10.3.2(3) Agent log.
- Format
-
The agent log is output in the following format:
yyyy/mm/dd hh:mm:ss.sss inf1 inf2 inf3 Message
The following table describes each item that is output.
Table 10‒3: Items in the agent log No.

- Note
-
Do not change the time at the PFM - RM host or the update date and time in the agent log file. If this information is changed, the agent log might not be output correctly because the output of the agent log uses information about the last update date and time of the log file.
