The comprehensive application topology visualization in Dynatrace, called Smartscape, has benefited my understanding of system dependencies. Even though Splunk has something similar, since we are using Dynatrace primarily for observability, we can get top-to-bottom visibility, from infrastructure to network to application front end. When integrated based on application requirements, we get a good grasp of what's happening during issues.

Smartscape topology helped us visualize the entire environment in real-time and identify issues such as memory leaks and high response times during load.

Every time we do not know how many services exist or why a particular service is working for this domain while we are in some centralized stage. But while coming to this Dynatrace dashboard, seeing all services in one place helps us think why this service is talking to this service. We can classify domain-level and regroup the domain. This way, it is helping us by giving a mental model and a mental map to track everything.
