Using date and time filters
The following are the date and time filters that you can use on charts:
• Start Updating:
Click Start Updating for P9000 Performance Advisor to update the selected chart window every
5 minutes with the newest data points. The newest data points are added to the right side of the
graphs in the chart window. It is in addition to the data points that are already plotted for the
specified date and time range. All the other data points are shifted one column to the left of the
graphs. The five minutes duration starts from the time you clicked the Start Updating button and
based on the system time where you are accessing P9000 Performance Advisor. If the performance
data is being collected for a frequency less than 5 minutes, all the data points accumulated over
the past 5 minutes are displayed. If the performance data is being collected for a frequency
greater than 5 minutes, there are no data points available when the chart is initially updated for
5 minutes. The data points appear in the next update cycle only for the delta duration.
When you click Start Updating, the chart re-renders itself to show the new values that are collected
from the host agent. The Start Time displays the time when the automatic update started, and the
End Time displays Continuous Update. It implies that P9000 Performance Advisor continuously
updates the chart with the newest data points till the time you click Stop Updating. Then, P9000
Performance Advisor stops the automatic re-rendering of the chart. The End Time displays the time
till when the chart was last updated.
