What action does Dynatrace automatically perform when an ActiveGate service is restarted?

When an ActiveGate service is restarted, all OneAgent instances automatically reconnect to the ActiveGate in order to recognize stored files. This reconnection process ensures that the OneAgent instances can regain access to the configurations and stored data necessary for monitoring and performance measurement.

The architecture of Dynatrace relies on the communication between OneAgent instances and ActiveGate services. Upon restart, this communication is re-established, enabling OneAgent to continue functioning effectively. This ensures continuity in data collection and monitoring capabilities within the Dynatrace environment.

The other options involve actions that do not occur automatically upon restarting an ActiveGate. For example, reconfiguring all OneAgent instances is not a standard function of this restart. Similarly, updating memory dump settings and clearing old memory dumps are specific administrative tasks that would not inherently happen just because an ActiveGate has restarted. Thus, the automatic reconnection of OneAgent instances is a key behavior that supports the overall functionality and reliability of the Dynatrace monitoring solution.
