Dynatrace Application Performance Management

At an AWS conference yesterday and I came across https://www.dynatrace.com/.  Was blown away by their Application Performance Management suite and how it compares with "traditional" monitoring tools like Nagios, Splunk etc.  I can't think of how many times this kind of functionality https://www.dynatrace.com/capabilities/application-topology-discovery/ would have been useful to me over the past 20 years.  If you've any need to better understand an application estate before undertaking migrations, either on-premise, in the Cloud, or as a hybrid, or if your current problem resolution tools leave something to be desired, i'd really recommend checking these guys out.
