OpenFlow flows are hard to debug

[Itzik Brown]

When debugging it's hard to follow the flows.
It may be a good idea to have a tool that will assist and make it easier to debug.
For example showing the name of the ports with the flow dumps. Sorting tables by priority etc.

do you mean inside the networking-odl?

Would the formatter from https://gist.github.com/djoreilly/3bcd6a81d9504bf740c4 help? It reformats and sorts the output of ovs-ofctl dump-flows, e.g:

table=0 priority=10 icmp6,in_port=qvo850de6e4-2d,icmp_type=136 actions=resubmit(,24)
table=0 priority=10 icmp6,in_port=qvo68f29806-97,icmp_type=136 actions=resubmit(,24)
table=0 priority=10 arp,in_port=qvo850de6e4-2d actions=resubmit(,24)
table=0 priority=10 arp,in_port=qvo68f29806-97 actions=resubmit(,24)
table=0 priority=2 in_port=int-br-eth1 actions=drop
table=0 priority=0 actions=NORMAL
table=23 priority=0 actions=drop
table=24 priority=2 icmp6,in_port=qvo850de6e4-2d,icmp_type=136,nd_target=fd93:21c2:fbbb:0:f816:3eff:fe32:c7a1 actions=NORMAL
table=24 priority=2 icmp6,in_port=qvo850de6e4-2d,icmp_type=136,nd_target=fe80::f816:3eff:fe32:c7a1 actions=NORMAL
table=24 priority=2 icmp6,in_port=qvo68f29806-97,icmp_type=136,nd_target=fe80::f816:3eff:fe85:13d1 actions=NORMAL
table=24 priority=2 icmp6,in_port=qvo68f29806-97,icmp_type=136,nd_target=fd93:21c2:fbbb:0:f816:3eff:fe85:13d1 actions=NORMAL
table=24 priority=2 arp,in_port=qvo850de6e4-2d,arp_spa=10.0.0.6 actions=NORMAL
table=24 priority=2 arp,in_port=qvo68f29806-97,arp_spa=10.0.0.5 actions=NORMAL
table=24 priority=0 actions=drop

It's better., thanks.
I see that there is a tool called easyovs https://github.com/yeasy/easyOVS
