CXF Logging feature integration 1.2.3. parts: - Collectors are responsible of harvesting monitoring data. Decanter provides collectors to harvest different kinds of data. We have two kinds of collectors: ☐ Event Driven Collectors automatically appenders. - Polled Collectors are periodically called by the Decanter Scheduler. They harvest data and send it to the Decanter appenders • Appenders receive the data from the collectors and are responsible
