Topology view

The topology view shows the arrangement of monitored components associated with its Navigator item. For attributes that can show their relationship to other attributes in the same group as connected objects, there is also the relational table based topology view.

As with the table view and chart view, you can use the topology view to display data from a query of your monitoring agents or from a custom ODBC query of a data source. The topology view provides a set of styling tools that enable you stress hierarchical relationships among related objects.

When you create a topology view that is based on a query (relational table based), each row of data returned becomes an object in the topology view. As with other query-based views, you can use the Properties editor to apply filters and thresholds to the view but with some differences:

In the Filters tab, the column check box determines whether the value is included in the hover help. Any formulas you write for the filters are applied in the same way as for other query-based views.
In the Thresholds tab, the chosen severity is applied to the topology as an alert indicator when the threshold is met.
