Build: #933
Status: Errored

Duration: 1 hr, 0 mins, and 20 secs
Commit: 14c136e (detailed_packet_drop_stats)
Author: Sriram Vatala via dev
Message: Detailed packet drop statistics per dpdk and vhostuser ports

OVS may be unable to transmit packets for multiple reasons and
today there is a single counter to track packets dropped due to
any of those reasons. The most common reason is that a VM is
unable to read packets fast enough causing the vhostuser port
transmit queue on the OVS side to become full. This manifests
as a problem with VNFs not receiving all packets. Having a
separate drop counter to track packets dropped because the
transmit queue is full will clearly indicate that the problem
is on the VM side and not in OVS. Similarly maintaining separate
counters for all possible drops helps in indicating sensible
cause for packet drops.

This patch adds custom stats counters to track packets dropped
at port level and these counters are displayed along with
other stats in "ovs-vsctl get interface <iface> statistics"
command. The detailed stats will be available for both dpdk and
vhostuser ports.
