This section describes the CFDP metrics that can be logged by the application. The snapshot of CFDP metrics is updated once a second with the completion status of each CFDP transaction. The CFDP metrics are divided into sending and receiving categories and grouped by file size ranging from less than a one megabyte to over a gigabyte. The metrics include calculations on the number and percent of files sent or received, the minimum, maximum, and average file transfer time, and the number and percent of files that required packet retransmission.

The following Metrics are provided for Sending and Receiving.
