Cropping data

You can change the time period for which data is displayed and on which recommendations are based.

What is cropping?

Cropping involves selecting a subset of data by specifying a time interval on a graph. The time interval is used to limit the data displayed by the Health Center, and also affects how much data is used to make recommendations. Any data recorded outside the time interval is ignored after cropping.

What can you crop?

You can crop data on graphs. Graphs are displayed in several perspectives, such as I/O and memory.

Some data, for example environment properties, are not time-based. If data are not displayed in graph form, they cannot be cropped.

Why it is useful to crop data

If you know that a problem took place at a particular time, you might want to crop the data to concentrate on the time interval of interest. Cropping helps reduce the quantity of data to process.

How to crop data

To crop data on a graph, start by specifying the beginning of the time interval. Specify the beginning by clicking one point in the graph. Next, drag to a second point in the graph. The second point corresponds to the end of the time interval. The graph adjusts so that only the selected time interval is displayed. Data recorded outside the time interval is ignored.

How to reset cropped data

You can reset the graph so that data is no longer cropped in two ways:
  • Right-click on the graph. Select Reset Cropping.
  • Double-click anywhere on the graph.
