Currently we are using NewRelic APM for applications hosted on Cloud Foundry(Tanzu Application Services) and soon we need to migrate to Dynatrace OneAgent for Cloud Foundry(Tanzu Application Services.
After installation of Dynatrace OneAgent via BOSH add-on, does NewRelic APM continue to work till app developer unbinds NewRelic service from app and restage the app.
As far as code level monitoring goes, Dynatrace OneAgent dynamically disables the New Relic OneAgent in processes that it monitors (Java, .NET, Node.js, PHP...). This happens at runtime, no configuration change is done, and is done to avoid any compatibility issues and ensure the stability of your system.
Whatever the solutions you choose, having two APM working on the same application at the same time could give you brain damage with analyses in case of conflict between those two.
Conflit or performance bottleneck has a high risk to happen because both will try to access the same kind of ressources at the same time.
Really bad idea.
