The following sections describe the steps for selecting elements and properties to create performance charts:
In the
view, the pane lists the types of performance information that has been gathered for an element, such as the number of alarms for each severity type ( ) and tring the changes in condition for an element ( ).The following topics are related to creating charts:
To create a chart:
In the
pane, select an element.Click the
tab.The

Duplicate property names can exist. Two or more properties attached to an element can gather properties with the same name. If duplicate properties display in the
pane, the associated profile name displays in parentheses.To automatically display properties in the
pane for the element selected in the pane, do any of the following:Select one or more properties in the
pane.To select multiple properties, press the Ctrl key, then click the properties.
To view chart profile information in a tooltip format, position the mouse over a property name.
The tooltip lists the profile associated with the property:
Consider the following concerning the properties:
Properties originate from either an external management system, such as PATROL, or from profiles created by the administrator.
If many properties are available, expand the
pane by dragging up its top border.If performance data is unavailable for the selected element, the
pane is empty, meaning a chart cannot be created.Click
.The charts display as a chart group in the
view.Depending on the number of selected chart properties, more than one chart might display. All charts created at the same time are considered in the same chart group. To understand the relevance of chart groups, see Section 8.3.3, Updating a Chart Group.
When charting SLA metrics (Availability and Outage Count), it can take up to several minutes before a chart registers an update, while updates for other property types are charted in near-real-time. In this case, the server has not yet recorded update data for these properties.
To create additional charts, repeat Step 1 through Step 5.
Clicking the
button creates a new chart beneath the most recent chart in the view. It is considered a separate chart group.To add a chart quickly:
Double-click a property in the
pane.The new chart displays in the
view. It displays with existing charts, but is a separate chart group.The standard Line chart tracks values using a line on the Y‑axis. The Area Line chart fills in the range between zero and the line value.
To create an Area Line chart:
Create a standard Line chart.
For instructions, see the steps listed earlier in this section.
In the
view, right-click the chart, then select .When selected, the Area Line chart displays. When deselected, the standard Line chart displays.
To show average condition values in a pie chart:
Create a Condition Line chart. For instructions, see the steps listed earlier in this section.
In the
view, right-click the chart, then select :A Pie chart opens in a separate dialog box.
Selecting too many data points can create an illegible chart. Also, all data points might not display in the chart. Magnify one area of the chart for a better view of data points. Other chart refinements include hiding profile names in the
pane, to make it easier to see when numerous properties exist.To zoom and magnify a chart:
Use the Zoom feature to magnify the display and refresh the data.
For more information, see Navigating Performance Charts and Navigating with Bookmarks.
To hide or show profile names in chart properties:
Right-click the background of the
pane, then select .When selected, the profile names display.
Charts display in chart groups in the
view. Clicking the button creates a new chart group. A chart group can contain one or more charts, depending on the number of chart properties selected.After creating a chart group, update charts in the group by making additional property selections or selecting a different element to chart.
HINT:Position the cursor over a data point to view a tooltip with relevant data for that point in time. For Condition charts, position the cursor over the actual data point (not the connector line).
To update a chart group:
In the
view, select the chart group.The element and properties used to create the charts appear highlighted in the
pane and pane, respectively.To chart a different set of properties for an element, select or deselect properties in the
pane.To create a chart for a different element:
Select a different element in the
pane.Then select properties in the
pane.Click
to update the current chart group with the changes.For example, select three properties and create three charts, deselect a property, then click
. The chart group redisplays using the last two selected properties, displaying only two charts.Data used to create a chart originates from the time the
view initially displayed. As time passes, it is necessary to refresh the chart with the most recent data from the native management system associated with the charted elements.To refresh chart data:
Do one of the following in the
view:Click a chart and then click
on the toolbar.Right-click a chart, then select
to refresh all charts in the group.To remove a single chart or the entire chart group:
