<p class="MsoNormal">Hi Igor/Cathy/Gord,<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">Sorry for the delay in replying.<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">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. <u></u><u></u></p>
<p class="MsoNormal">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. <u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">I have just mentioned my idea on this. Can I please know your opinion on this and provide your comments? <u></u><u></u></p>
