Network Statistics
Overview
Network statistics are collected if CONFIG_NET_STATISTICS is set.
Individual component statistics for IPv4 or IPv6 can be turned off
if those statistics are not needed. See various options in
subsys/net/ip/Kconfig.stats file for details.
By default, the system collects network statistics per network interface. This
can be controlled by CONFIG_NET_STATISTICS_PER_INTERFACE option.
The CONFIG_NET_STATISTICS_USER_API option can be set if the
application wants to collect statistics for further processing. The network
management interface API is used for that. See Network Management for
details.
The CONFIG_NET_STATISTICS_ETHERNET option can be set to collect
generic Ethernet statistics. If the
CONFIG_NET_STATISTICS_ETHERNET_VENDOR option is set, then
Ethernet device driver can collect Ethernet device specific statistics.
These statistics can then be transferred to application for processing.
If the CONFIG_NET_SHELL option is set, then network shell can
show statistics information with net stats command.
