This section contains links to API documentation pages with detailed descriptions of each UM statistic.
Note that certain statistics are initialized to the maximum unsigned value for the fields, i.e. all bits set (-1 for a signed value). This special value indicates that the field has not yet been calculated. This is used for the "min" statistic in a "minimum / maximum" statistics pair. For example, nak_tx_min is initialized to the maximum unsigned long, while nak_tx_max is initialized to zero.
Although the API suggests that these statistics are on a topic basis, they are actually on a transport session basis. Receiver objects are sometimes passed in as a means of identifying the desired transport session(s).

Although the API suggests that these statistics are on a topic basis, they are actually on a transport session basis. Source objects are sometimes passed in as a means of identifying the desired transport session.
