Host and Smartscape
In this next few sections, review what the OneAgent automatically discovered for the host, services, processes, and the complete dependency mapping for the easyTravel application.
As you plan your migration, each of these views will give insights in accessing the profile, consumption and dependencies to other systems and services.
Host view
From the left-side menu in Dynatrace choose hosts then click on the host with the prefix of YOUR_LAST_NAME-workshop-ez.
On host page, you will see basic infrastructure information for the host.
- Now expand the Properties section to see data about the host:
- Host resource metrics (CPU, memory)
- Host availability
- Discovered processes. In this case most of which are Java applications running in Tomcat.
Smartscape view
Let’s see how Dynatrace can visualize these processes using Smartscape.
- Just click on the
...box on the to the right of the host name - pick Smartscape view menu option
- this will open Smartscape filtered to this EC2 Instance
Feel free to explore the Smartscape.
About Smartscape
Smartscape is Dynatrace’s near real-time environment-topology visualization tool, is one of the most powerful features of Dynatrace. Smartscape auto-discovery delivers a quick and efficient visualization of all the topological dependencies in your infrastructure, processes, and services:
- On the horizontal axis, it visualizes all ingoing and outgoing call relationships within each tier
- On the vertical axis, it displays full-stack dependencies across all tiers
- Datacenter
- Hosts
- Process
- Service
- Application
Enterprise have many hosts, services, and application that are ever changing. The ability to automatically discover and change as the environment changes is a key feature that Smartscape delivers. Below is a picture taken from a more complex environment.
How this helps
Smartscape shows all the dependencies of a given service. Those include connections to queues, web servers, app servers, and a native process. The host view shows historical and live time-series data for usage as well as the consuming processes. This information allows us to better plan the migration, as all depending services must be considered during the migration.
