What is the frequency of data sent by the Collector to the Engine?
The Collector sends data to the Engine every 60 seconds by default. If the internal buffer of the Collector is full before a period of 60 seconds has elapsed, the Collector flushes the buffer and sends the data to the Engine right away. The default maximum packet size is 1500 bytes.
The Collector captures different types of data at different rates from the host device. Some data are periodically repeated because UDP packets may get lost on the way or because the data may have changed on the device.
