The Application Stack, or AppStack, is a term used to describe the various layers that make up a complex application delivery infrastructure. The AppStack Environment view is an interactive visual mapping within Orion that provides an in-depth perspective through the entire environment to help identify the root cause of performance and availability issues.
AppStack automatically gathers information about objects in your environment, as well as their respective relationships, and displays them in a customizable view. Some relationships, such as groups and dependencies can be defined by the user.
The AppStack environment supports only server and virtual server node types.
If you have Cloud Infrastructure Monitoring configured, any AWS cloud instances (and applications) managed as nodes also display AWS data and relationships in AppStack.
To access the AppStack, click My Dashboards > Environment. You can filter the application view through using the filter options and filter properties. You can save and reuse these filters as layouts to display specific views of the AppStack.
In the AppStack view, you can hover-over each node and application to see a tooltip of data and status. This view provides quick insight into issues in the stack and overall statistics. Select each item on the view to load related items throughout the environment. See Understanding the AppStack data for details on icons and colors of icons for at-a-glance monitoring.
You can further understand, monitor, and customize the AppStack with the following:
Using AppStack as a troubleshooting tool is fairly straightforward. Simply navigate to the AppStack Environment view, and click on an object to see related objects. To investigate further, navigate to the Details page of the object or any related object.
For example, the illustration below displays all objects in the current environment. The application, MSSQLSERVER, is in a Critical state, as indicated by its icon. To see what this application is related to, click the MSSQLSERVER icon.
As you select objects in the AppStack, the system automatically updates the view to select and highlight related objects. In this example, MSSQLSERVER is selected. Once it is selected, related objects are highlighted by the fading of unrelated objects, as shown:
If you want to completely hide unrelated objects from the view, you can click the Spotlight. Select an object then click Spotlight in the upper right-hand corner to hide them.
To navigate to the details page of a selected object, click the icon of the selected object next to the chart at top or double-click the larger icon in the main view. You can review and managed the critical and warning issues per node.
