Subject: Tools for sampling ethtool --statistics
Date: Wed, 20 Jan 2016 10:13:11 +0100 [thread overview]
Message-ID: <20160120101311.5266cac6@redhat.com> (raw)
Hi All,
I wrote a small tool[1] to extract ethtool --statistics|-S, sample and
present it in a more human readable manor. You might also find this
useful...
https://github.com/netoptimizer/network-testing/blob/master/bin/ethtool_stats.pl
The reason I wrote this script is that the mlx5 driver (Mellanox 100 Gbit/s)
does not report correct ifconfig stats. It reports the HW counters,
not what the network stack is able to handle. I/we obviously need the
stack number when working on improving the stack.
