The Tree tab of the PurePath dashlet displays the contributors to the PurePath, selected in the PurePath tab, arranged as a tree that maps the calling hierarchy of the contributing methods. It contains the same columns as the Contributors tab. Methods highlighted in the Contributors tab are also highlighted in the PurePath Tree. Dependencies between instrumented methods are illustrated by the tree structure. When you select a method in the Contributors tab, the PurePath tree scrolls automatically to the selected contributor method, and a yellow arrow appears to the left of that method. With this functional interaction between the Contributors tab and the PurePath tree, you can efficiently navigate to desired methods within PurePaths to see context-referred information for this method.
The whole tree or parts of it can be expanded or collapsed to focus on the important methods calls and to hide parts of the PurePath not relevant for the current performance diagnosis task. The state of the Tree tab is linked with the Contributors tab. If a new method is selected within the Contributors tab, the Tree tab is updated to also show the selected method. If required, the expanded and collapsed parts of the Tree tab are rearranged to focus on the new selection.
The call hierarchy of the selected PurePath can span multiple threads or processes, depending on the applied sensors. To indicate thread or process changes within a PurePath, the following special nodes are inserted within the tree view:
- Synchronous Path: A node that groups the nodes of the child path that is executed synchronously on another Agent or thread. The parent node of this Synchronous Path node blocks until the child path has finished its execution.
- Asynchronous Path: A node that groups the nodes of the child path that is executed asynchronously on another Agent or thread.
- Asynchronous Invocation: A grouping node of one or more Asynchronous Paths as a single call that can cause several threads or Agents to start processing. For example, sending one JMS message can cause several subscribers on a JMS topic. A Synchronous Invocation grouping node is not shown for a Synchronous Path, because all synchronous invocations lead to exactly one Synchronous Path.
A distributed PurePath is the PurePath which was captured by several AppMon Servers.
If your Client is connected to all of these servers, you can trace distributed PurePaths across those servers. Select the required PurePath in the PurePath tab and click the Find distributed PurePaths button in the Tree tab. Distributed nodes has either or icon. Click the icon or right-click and select Cross-Server Drill to open related PurePaths in the new PurePaths dashlet.
Tree context menu
- Drill Down: Right-click a PurePath and select a dashlet from the cascading menu to display information for just that PurePath in the selected dashlet.
- Show in Dashboard: Right-click a PurePath or select multiple PurePaths, then right-click the dashlet and select from the cascading menu to open a dashboard or create a new dashboard filtered for the selected PurePath.
- Add Snapshot to Dashboard: Display the dashlet in the selected dashboard with the time frame automatically set to last 30 minutes.
