Use the Time Settings control to set the window of time for the graph's data.
You can select one of the preset time periods, or you can use the date and time pickers to manually set the window's Start and End times. If the Start and End times are changed manually, the window size will be set to Custom.
The time settings pane also allows you to select the Detail level and Averaging settings for the graph data.
Selecting the Detail Level
Systems have an agent that continuously collects system data. The Detail level selection allows you to control the data detail level vScape requests for Systems. The following table describes each detail level.
TIP: Because of the way data is gathered, Detail level selections apply only to selected System items.
NOTE: Although the selected Detail level is different in each of the example screen shots below, the selected window of time is identical.
Detail Level | Description |
|---|---|
Auto | Displays the highest level data available that provides sufficient data to fill the entire time window is used, and the resultant data detail level is shown in parenthesis along with the selected window of time. For all other levels, the requested level of data detail is used regardless of whether there is sufficient data to fill the selected time window.
|
High | Provides the finest data granularity; data points are collected every 15 seconds and are retained for 72 hours.
|
Medium | Data points are collected every 10 minutes and are retained for 30 days.
|
Low | Provides summarized data; data points are collected every 2 hours and are retained for 3 years.

Select the Averaging Setting
The Averaging setting controls how the raw data points are treated before being graphed. If Auto is selected, the raw data points will be graphed without being altered if there are not too many points to graph (high detail and/or long window time). The maximum number of points that can be graphed is 500. Above that, the chart will average the points so that they meet the 500 point maximum. If the setting is anything other than Auto, the data is averaged into periods as defined by the setting. For example, if the Averaging setting is 1 HR and the time window is the last 24 hours, there will be 24 data points graphed. If the raw data is at a higher sample rate than 1 hour, the points occurring in each hour are averaged to get the value for that hour's data point.
NOTE: When a series is being averaged (because of too many points or a manual setting), a * will proceed the series name.
