What is required for Dynatrace OneAgent to begin monitoring the Apache process after a restart?

For Dynatrace OneAgent to begin monitoring the Apache process after a restart, a complete reload of the web server is necessary. This ensures that all components of the Apache service, including its worker processes, are restarted and properly re-initialized with the monitoring hooks that OneAgent provides. A complete reload guarantees that all configuration changes and monitoring capabilities established by the OneAgent are effectively applied.

Partial reloads or simply restarting the worker processes may not adequately re-establish the monitoring connections or may leave some components unmonitored. Additionally, installing a new version of Dynatrace OneAgent is not typically required for monitoring an existing Apache process unless there are specific updates or features included in the latest version you wish to leverage, but it is not a prerequisite for monitoring after a restart. Thus, the requirement of a complete reload is critical to ensure that Dynatrace OneAgent can fully integrate with the Apache processes.
