You can also keep the historical data manageable by tailing the file. Log all values into a single file, such as history.log
At the beginning of the log file processing, execute:
Code:
tail history.log > fileToProcess.log
This will give you a smaller file from which to get your historical data. The size of your history.log file will not matter, your processing file will always contain the last 10 entries.

wbemlogviewer(1M)wbemlogviewer(1M)NAME
wbemlogviewer - start WBEM Log Viewer
SYNOPSIS
/usr/sadm/bin/wbemlogviewer
The wbemlogviewer utility starts the WBEM Log Viewer graphical user interface, which enables administrators to view and maintain log
records created by WBEM clients and providers. The WBEM Log Viewer displays a Login dialog box. You must log in as root or a user with
write access to the rootcimv2 namespace to view and maintain log files. Namespaces are described in wbemadmin(1M).
Log events can have three severity levels.
o Errors
o Warnings
o Informational
The WBEM log file is created in the /var/sadm/wbem/log directory, with the name wbem_log. The first time the log file is backed up, it is
renamed wbem_log.1, and a new wbem_log file is created. Each succeeding time the wbem_log file is backed up, the file extension number of
each backup log file is increased by 1, and the oldest backup log file is removed if the limit, which in turn is specified in the log ser-
vice settings, on the number of logfiles is exceeded. Older backup files have higher file extension numbers than more recent backup files.
The log file is renamed with a .1 file extension and saved when one of the following two conditions occur:
o The current file reaches the specified file size limit.
o A WBEM client application uses the clearLog() method in the Solaris_LogService class to clear the current log file.
o A WBEM client application uses the clearLog() method in the Solaris_LogService class to clear the current log file.
o A user chooses Action->Back Up Now in the Log Viewer application.
Help is displayed in the left panel of each dialog box. Context help is not displayed in the main Log Viewer window.
The WBEM Log Viewer is not the tool for a distributed environment. It is used for local administration.
The WBEM Log Viewer allows you to perform the following tasks:
View the logs
Set properties of log fiClick Action->Log File Settings to specify log file parameters and the log file directory.
Back up a log file Click Action->Back Up Now to back up and close the current log file and start a new log file.
Open historical log fileClick Action->Open Log File to open a backed-up log file.
Delete an old log file Open the file and then click Action->Delete Log File. You can only delete backed-up log files.
View log record details Double-click a log entry or click View->Log Entry Details to display the details of a log record.
Sort the logs Click View->Sort By to sort displayed entries. You can also click any column heading to sort the list. By default,
the log entries are displayed in reverse chronological order (new logs first).
EXIT STATUS
The wbemlogviewer utility terminates with exit status 0.
