Use the values from the current chart or table to model
threshold conditions and then use the results in a new situation.
Historical views are particularly valuable for researching thresholds.

About this task
The attribute values that are used for modeling are especially
valuable for comparing with historical data samples. Take these steps
to work with the situation modeling feature and, if you choose to,
create a situation. Text attributes cannot be modeled. Only display
item, which has a checked box
Procedure
- Right-click a table row or chart point containing numeric
attributes to monitor and click
Model Situation.
The Select attribute window is opened with the attribute
group preselected. If you opened the menu from a chart, attributes
are preselected.
- In the Select attribute window, select the attributes
to model:
- Click an attribute to select it. You can also use Ctrl+click to select multiple
items and Shift+click to select all items between the item last selected
and this one. You can select up to
10 attributes.
- Select numeric attributes of interest.
After you click
OK, the Model Situation
window is opened with a chart displaying the selected numeric attributes
and their values (from the selected row).
- If historical data samples are available, the last 24 hours are
displayed in a plot chart. If no historical data has been collected,
the current data samples are displayed in a bar chart.
- Any non-numeric attribute values are shown but are non-selectable.
The exception is a display item, which is a key attribute in some
multiple row attribute groups and shows in the Model Situation window.
In situation modeling, it can be used to select different data rows.
In a situation definition, a display item can be selected as an Advanced option
that enables the situation to open multiple events: once for each
row that meets the condition.
- A message informs you if no modeling chart is displayed.
This happens if the situation override is for a multiple-row attribute
group that has no display item.
- Use the modeling tools to apply different threshold scenarios;
click Recalculate to render the chart with
the modified argument set.
- To create a situation populated with values from the Condition
column, click Create Situation. Enter the situation
name and optional description.
