Understanding the AppStack environment

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 display them. Some relationships, such as groups and dependencies can be defined by the user.

Important: As a standalone product, AppStack is available in the software versions listed below. If you own two or more of the listed products, AppStack does not function properly unless each version of the software is upgraded to the versions listed.

  • Server & Application Monitor (SAM) 6.2 and later
  • Storage Resource Monitor (SRM) 6.0 and later
  • Virtualization Manager (VMan) 6.2 and later
  • Web Performance Monitor (WPM) 2.2 and later
  • Database Performance Analyzer (DPA) 10.2 and later

The AppStack Environment View

Imagine you work for a company comprised of many employees that work in various departments. In this example, you work in the Engineering department as an engineer:

Now imagine you call in sick and are unable to work for two weeks. Certain employees in various departments are affected by your absence. Others are not be affected. The illustration below highlights the employees who are affected by your absence by fading those who are not affected.

Focusing on only the people who are affected by your absence can be beneficial from a task management perspective. Therefore, completely hiding those not affected by your absence gives a clean and concise view, displaying only the necessary information.


Now, instead of employees, imagine we are talking about your entire IT environment. The goal of the AppStack Environment view is to help you quickly assess the impact a given object has on its related objects. This relational view displays the status of individual objects in your IT environment through the Orion web console. Objects are categorized and ordered from left to right, with the worst status being shown on the left side of the view.

Clicking an object shows everything related to that object by fading unrelated objects, as shown:

Clicking Spotlight removes the faded, unrelated objects from the view entirely.

Clicking the selected object at the top, or double-clicking it in the view, takes you to the Details page for that object for further investigation.
