Viewing the application flow of a transaction instance enables you to see details for each component of the flow. As shown in the following example, each component is displayed as a node in the application tree. Click a node to see the details pane for that specific node. The arrows between nodes show the transaction flow. The technology used in the specific flow between nodes is displayed on the arrow.
Above each node is displayed the accumulated time, in milliseconds, spent on the node, as well as the percentage of time spent on the node out of the total time spent on the entire Transaction Instance.
To view application flow details
- On the Business Transaction Details window, click the Application Flow tab.
- Click a node.
Node details are displayed in the pane to the right of the flow tree.
