HP 3PAR System Reporter Software - Manual (Page 14)

For example, when we have log files HP3PARInfo.log to HP3PARInfo.log.4, and HP 3PARInfo
is run again, HP3PARInfo.log.4 is overwritten and lost.
NOTE: You cannot configure the number of log files that need to be retained. If you want to
retain a particular log file, you must back up the file.
NOTE: When multiple instances of HP 3PARInfo are run simultaneously, the log file is not rolled
over; all the logs are logged into HP3PARInfo.log. If you need to analyze the logs of a particular
instance, look for the Process ID of the instance, run the grep command to find the lines of that
instance, and redirect those lines to a temporary log file. This makes the analysis of the particular
instance easier.
For example, if you want to analyze logs of process id 11380, run the following command on
Linux:
cat /var/log/HP3PARInfo/HP3PARInfo.log | grep "11380" >
/tmp/HP3PARInfo_Option_i.log
A new log file that contains the logs of process id 11380, HP3PARInfo_Option_i.log, is
created. This log file can be used for analysis.
