Hi MohanKumar, Thanks for the reply.
Is the design part for the “OAM Operation Manager for SFC” done? What is the approach being used to monitor the SFC? If the design is already done, I would like to contribute in implementing it. Please provide your comments.

Treat hyperlinks and attachments in this email with caution** Hi Rajeev, The Chain Monitoring is the missing piece in networking-sfc . Vikram and myself were discussed to introduce "SFC Manager" [1] (basically OAM tool ) few cycle before. It'll continuously monitor an existing SFC chain, when any SF VM goes down or any packet drop. It'll trigger alert and capture corresponding logs . But we haven't started any implementation on this. Feel free to discuss with community, IMO this feature will be great addition to networking-sfc [1] https://bugs.launchpad.net/networking-sfc/+bug/1513368 <https://clicktime.symantec.com/a/1/oyvdp2ozE_Pe2sKTM51_kVGy1ODcQYS_L50v9C-IyKo=?d=OZb6_jQ3JlDcR2AISJ1S1yWSl9wA-da9R6WweBZh8-1xFSm7MxSA9a4SYoOw7U5fTTE8TgbqfudjFvUJGjDkrnVR8mWytf4M3eN4AD71w1P20EuGgVBYqX2e4XU1RLCLPuDzEem8Pvb7DaVjt_oEU15hkt_CfSTEUKh58nKrnbrfyy9rDd5XIZscEY5gl3pbQ5CoXChMOmfq68AE2WCT9a01j26KThkBjxPJbv7zay4R1vkxAxl07G4VZ26lvhz-CLOS6io8hJGjhaWkAJN_i67NzGOXXjipBTRt860ew1Njxrns15bG_IJ58TV9RRw-EMQ0HNftqhXlA28RRbuLvqfjJmivRjKHrMXjeKah9B7TvU1XTn7fAwJvIbcHA8zejHC_MUDNNpDMJQ7RfC6A0v5hl8qhiG2UCM-axWeSN5erVE652SbORAGMTScANtK7PL02O8Da9-W30pJr9e8haxOIGYVgHA%3D%3D&u=https%3A%2F%2Fbugs.launchpad.net%2Fnetworking-sfc%2F%2Bbug%2F1513368> IRC: #networking-sfc Weekly Meeting: https://wiki.openstack.org/wiki/Meetings/ServiceFunctionChainingMeeting<https://clicktime.symantec.com/a/1/6dNKaHpOkefxWGyCJEXAIE-cQCSPzu0gOs-V_OdWGO4=?d=OZb6_jQ3JlDcR2AISJ1S1yWSl9wA-da9R6WweBZh8-1xFSm7MxSA9a4SYoOw7U5fTTE8TgbqfudjFvUJGjDkrnVR8mWytf4M3eN4AD71w1P20EuGgVBYqX2e4XU1RLCLPuDzEem8Pvb7DaVjt_oEU15hkt_CfSTEUKh58nKrnbrfyy9rDd5XIZscEY5gl3pbQ5CoXChMOmfq68AE2WCT9a01j26KThkBjxPJbv7zay4R1vkxAxl07G4VZ26lvhz-CLOS6io8hJGjhaWkAJN_i67NzGOXXjipBTRt860ew1Njxrns15bG_IJ58TV9RRw-EMQ0HNftqhXlA28RRbuLvqfjJmivRjKHrMXjeKah9B7TvU1XTn7fAwJvIbcHA8zejHC_MUDNNpDMJQ7RfC6A0v5hl8qhiG2UCM-axWeSN5erVE652SbORAGMTScANtK7PL02O8Da9-W30pJr9e8haxOIGYVgHA%3D%3D&u=https%3A%2F%2Fwiki.openstack.org%2Fwiki%2FMeetings%2FServiceFunctionChainingMeeting> Thanks., Mohankumar.N On Thu, Jul 27, 2017 at 11:30 AM, rajeev.satyanaray...@wipro.com<mailto:rajeev.satyanaray...@wipro.com> <rajeev.satyanaray...@wipro.com<mailto:rajeev.satyanaray...@wipro.com>> wrote: Hi Igor/Cathy/Gord, Sorry for the delay in replying. As part of monitoring the SFC, I think maintaining the details of “Number of flows assigned to a given SFC”, “Number of packets/bytes dropped/hit due to the policies at each Service Function entry/exit points or for the entire SFC” would be good to start with. I feel based on some of these details, an operator can know how much the virtual switch is loaded and take a call on whether to add a new SFC, or it could even help during debugging which service function has exactly caused the disruption to SFC. As a first step, I think it would be good to add meters to provide “number of packets/bytes hit due to policy at the ingress and egress of the entire SFC” and to realize that, we would need to add specific pollsters. We can use neutron_client API to fetch the ingress and egress port details and fetch the corresponding flows for those specific ports(also get flow_infos from flow_classifier and then use them to dump_flows matching those flow_infos) and fetch the no.of packets hit due to policy from them. I have just mentioned my idea on this. Can I please know your opinion on this and provide your comments? Thanks and Regards, Rajeev.
