I dont know of any immediate plans to implement it.

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
<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
