What port does the Dynatrace OneAgent use to communicate with the Managed Server?

The Dynatrace OneAgent communicates with the Managed Server using port 8443. This port is specifically designated for secure communication, typically over HTTPS, ensuring that the data transmitted between the OneAgent and the Managed Server is encrypted and secure. By utilizing port 8443, Dynatrace can maintain a consistent communication channel for performance monitoring, metrics collection, and the delivery of insights, all while complying with security best practices.

Port 443 is commonly used for secure web traffic, but in the context of Dynatrace, port 8443 serves the specific purpose for OneAgent and Managed Server interactions. Ports like 8080 and 3306 are generally associated with other services, such as web servers or database connections, and do not relate to the typical setup of Dynatrace's infrastructure. Therefore, 8443 is the correct choice as it is explicitly used for the necessary communication between the OneAgent and the Managed Server in Dynatrace's architecture.
