Processes and Services
In the Smartscape view, we saw the visualizations of the relationships in vertical stack and as well as the relationships spatially. Now Let’s view the process and service running on the host.
As you plan your migration, you need more than just host level metrics. Knowing the details for each services, BEFORE you change it, will lower the risk of impacting the business.
Host view
Return back to the host view for the host with the prefix of YOUR_LAST_NAME-workshop-ez and locate the Processes and Containers section.
Click on the com.dynatrace.easytravel.business.backend.jar easytravel-*-x* process in the Processes and Containers section to open the process detail view.
Process view
You should be on the process page where you will see information for this backend process. Follow the picture below to locate the following:
- Click on the Properties line to toggle on/off to see additional data about the process such as JVM version and open ports

- Click to view the services that are served by this process. In this case there are multiple
- Click to view the processes that this process calls (Outbound)

How this helps
Very quickly we have seen what processes and services are running on a host AND more importantly, what processes and services call (inbound) and are being called (inbound). Having a real-time picture is certainly more accurate that out of date documentation.
