Maybe starting with Ahmed’s use case. ;D

Ok Thanks Brady,
and regarding the implementation of service-statistics, will it be
in the next release or still not in your near Future plans ?
Best regards,

There is a way that's not quite as elegant, but that will
definitely work. You can look at the OpenFlow statistics for
each RSP.
In OPNFV with Netvirt, you can do this by looking at the
classifier flow:
cookie=0x1110010001230255, duration=84892.936s, table=11,
n_packets=0, n_bytes=0, tcp,reg0=0x1,tp_src=2000,tp_dst=80
actions=move:NXM_NX_TUN_ID[0..31]->NXM_NX_NSH_C2[],
push_nsh,load:0x1->NXM_NX_NSH_MDTYPE[],load:0x3->NXM_NX_NSH_NP[],
load:0xc0a80012->NXM_NX_NSH_C1[],load:0x7b->NXM_NX_NSP[0..23],
load:0xff->NXM_NX_NSI[],load:0xc0a80012->NXM_NX_TUN_IPV4_DST[],
load:0x7b->NXM_NX_TUN_ID[0..31],output:9
Or look at the SFC NextHop flows:
(Notice the RSP ID: nsp=123)
cookie=0x14, duration=304.694s, table=152, n_packets=6,
n_bytes=444, priority=550,nsi=255,nsp=123
actions=load:0xc00000a->NXM_NX_TUN_IPV4_DST[],goto_table:158
Notice that if you have multiple SFs on the chain (as
indicated by multiple nsi matches for the same nsp), you'll
need to add all the counters for each SF on the RSP.

Thanks Brady for reply.
So there is no any other way to know how much traffic
passed in each path ?

Ahmed,
What you have found is a YANG model in SFC:
https://github.com/opendaylight/sfc/blob/stable/beryllium/sfc-model/src/main/yang/service-statistics.yang
The model has been defined, but it hasnt been
implemented, so I dont believe it will be possible to
retrieve any related statistics.

Brady

Hi All,
I have found in SFC Beryllium release in the SFC
Model that I can get statistics for each RSP (such
as bytes-in,bytes-out, packets-in, packets-out).
I would like to know how to get such info using
REST API ? and is it working in Berylium release ?
Best regards,
Ahmed
