Maximum storing period for monitoring
For a specified sampling interval, the SVP can store a maximum of 1440 data collection events. Based on this number and the sampling interval, you can calculate the maximum storing period for the statistics as the sampling interval multiplied by 1440. For example, if you set the sampling interval to 1 minute, the maximum storing period for the statistics is 1 day (24 hours):
1 minute x 1440 = 1440 minutes = 24 hours = 1 day
If you set the sampling interval to 15 minutes, the maximum storing period for the statistics is 15 days:
15 minutes x 1440 = 21600 minutes = 360 hours = 15 days
This maximum storing period is the maximum range of display in the Monitor Performance windows. When you specify 1 minute for the sampling interval as in the example above, Performance Monitor displays the statistics for a maximum of 1 day (24 hours) in the lists and graphs. When you specify 15 minutes for the sampling interval, Performance Monitor displays the statistics for a maximum of 15 days in the lists and graphs.
