Introduction

The following is an introduction to the average graph in CapaInstaller.

The average utilization index is calculated for each day and stored in the CapaInstallerdatabase. This average can be useful in identifying general performance issues on computers in your organization.

In order to make it easy to analyze the data, a graph consisting of a series of columns is available to visualize the average utilization index for a computer. Each column represents the average utilization index for one day, and by hovering the mouse over a column you can see the date and value that the column represents.

Graph

In the above screenshot, you can see the average graph, zoomed in on the 13th of February to 4th of March for a selected computer. This view is divided into three main sections which are described below.

Overview graph
From the bottom of the view, a small graph is shown which covers the current date and the previous 6 months. The earliest and latest dates are shown on the left and right sides, to show which period is available. If any data has been collected for the computer in this period, it can be seen here. The part you have zoomed in on will be colored gray and marked with two vertical black lines as above.

Time period
The time period controls show what period is seen on the average graph. These controls will be updated with the correct values regardless of what caused the period to change. The period shown on the average graph will change according to any changes you make on these controls. Besides setting the time period, you also have the option of showing all days on the graph, or only those days with data. Unchecking the checkbox and only seeing days with data, might make it easier to notice a trend in performance. Below is a screenshot of the same time period as above, but with this setting unchecked.

Average graph
On this graph you can see average utilization index data for the period of time, indicated by the controls on the right. In the bottom right corner, the number of days with data is displayed. The y-axis represents percentages from 0 to 100, while the x-axis represents days.
You can change the time period directly on this graph as well. Clicking and holding the left mouse button, and then dragging to the right will move the graph backward in time. Dragging it to the right will do the opposite.

The information presented directly above the average graph represents data for the position of the mouse cursor. As you move the mouse over the graph, these information labels will be updated, and show the date as well as the average utilization index for the day which the column represents.
