(ii) PSL Output Interval
Specify the interval at which statistical information is collected and output to the statistical information history
file. The default interval is 5 minute s. If changing the in terval, specify a value from 1 to 60.
(iii) Adjustment of Output Interval
Statistical information may not be output at the currently specified interval if there are too many disk array
components. Specify this item to determine whether to automatically change to an interval at which statistical
information can be output.
Manual: The currently specified interval is not changed automatically to an interval at which statistical
information can be output.
Automatic: The currently specified interval is changed automatically to an interval at which statistical
information can be output.
(iv) Output PSL when iSM Server Starts
Determine whether to automatically start the output of statistical information for all the disk arrays that can use
PerformanceMonitor when the iSM server starts.
Don’t Output: Statistical information output is not automatically started.
Output: Statistical information output is automatically started. However, statistical information output is not
automatically started for disk arrays for which statistical information output was stopped in the previous
operation, and the previous operation state is retained instead.
(v) Display Refresh Rate
Specify the number of times data updated per minute in the numeric value table and the time-series graph on the
performance monitoring screen. For details, refer to the “PerformanceMonitor User’s Manual”. The default
number of times is 1 per minute. If changing the number of times, specify a value from 1 to 6.
(vi) Interval
Specify the monitoring interval as a threshold monitoring condition.
A value 1 to 60 (minutes) can be specified. The default monitoring interval is identical to the display refresh
rate.
(vii) Minimum I/O Count
Specify the minimum number of I/O operations as a threshold monitoring condition.
A value 1 to 120 (the number of times/minute) can be specified. The default minimum I/O count is 60 (times
per minute).
• In [Performance Optimization Information], specify information about the performance optimization of disk arrays.
(viii) Log File Folder
Specify the folder for containing the performance optimization log file. The folder name can be specified with
up to 192 bytes.
The default folder is “[installation destination folder]\etc\optlog”. If changing the folder, click the [Browse]
