7.3.1 Log information types
- Organization of this subsection
(1) System log
The system log contains information that indicates the system status and reports problems. In Windows, this information is output to the event log file.
For details about the output format, see the chapter that explains log information in the manual JP1/Performance Management Reference.
- Note about operations in a logical host environment
-
In addition to the system log of Performance Management, you need the cluster software's log in order to check the control of Performance Management by the cluster software.
(2) Common message log
The common message log contains information that indicates the system status and reports problems. This log contains more detailed information than the system log. For details about the name of the output destination file for the common message log and the file size, see 7.3.2 Log file and folder list. For details about the output format, see the chapter that explains log information in the manual JP1/Performance Management Reference.
- Note about operations in a logical host environment
-
When Performance Management is running on a logical host, the common message log is output to a shared disk. Because log files located on the shared disk are inherited along with the system when a failover occurs, messages are recorded in the same log file. If you want to check a history of operations on Performance Management performed from the cluster software in addition to the Performance Management system log, the log of the cluster software is required.
(3) Operation status log
The operation status log contains the log information that is output by PFM - Web Console. For details about the name of the output destination file for the operation status log and the file size, see the chapter that explains error detection in the JP1/Performance Management User's Guide. For details about the output format, see the chapter that explains log information in the manual JP1/Performance Management Reference.
(4) Trace log
The trace log is used to collect log information that can be used for investigating a problem's history, and for measuring the processing time each process uses.
The trace log is output to the log file that each service of the Performance Management program has.
- Note about operations in a logical host environment
-
When Performance Management is running on a logical host, the trace log is output to a shared disk. Because log files located on the shared disk are inherited along with the system when a failover occurs, messages are recorded in the same log file.
(5) Collected logs
Collected logs contain log information about processes related to record collection, and are output by PFM - RM for Virtual Machine. Logs are collected for the purpose of obtaining detailed information about these processes when a problem occurs. For details about the output destination, see 7.3.2(3) Collected log.
