| H A D | statistics.rst | 4 Interface statistics
10 This document is a guide to Linux network interface statistics.
12 There are three main sources of interface statistics in Linux:
14 - standard interface statistics based on
16 - protocol-specific statistics; and
17 - driver-defined statistics available via ethtool.
19 Standard interface statistics
22 There are multiple interfaces to reach the standard statistics.
44 Queue statistics argument
47 Queue statistics are accessible via the netdev netlink family.
