Visual Application Discovery & Analysis (VADA) allows you to automatically discover and map your applications and view live health states and performance across your entire application stack. This article is a walkthrough of using VADA on your own SquaredUp instance. For more in depth information about how VADA works take a look at Visual Application Discovery & Analysis (VADA).
VADA is powered by SCOM agent tasks, including "Get Netstat" tasks for Windows and Unix, which are run on demand on a node when VADA discovery is performed against it. VADA then uses that Netstat information to dynamically map connections between your nodes, using advanced modelling algorithms.
These agent tasks are included in Data on Demand management packs, so before you start make sure you have the Data on Demand Management Packs installed.
You will need the name of web server in a simple 2-tier or 3-tier application. The application should be currently running with user load.
- In the Search... box, enter the name of your web server and select it from the results.
In the drilldown, select the App Discovery perspective.
The server should appear on the canvas of the Visual Application Discovery and Analysis tile.
If you have the management packs correctly installed, discovery will automatically run and connections to other servers should appear on the canvas.
The processes that the connections are made from appear under the server name.
If processes appear that are not part of the application, for example infrastructure components and other management tools, these can be filtered. Hover over the process and click filter. Click filter for this node only.
Filtering can be performed on a global or a local basis, and your global filters can be managed from the right-hand menu ☰ > system > VADA
Continue to click on other servers that are part of the application until all servers have been discovered.
- Click the analyze button in the tile menu to visualise the health and performance of the servers in your application.
Once the application topology has been discovered, you can choose to save the application as a new dashboard or SCOM Distributed Application.
