hi,

i'm using the top flows application and am trying to view some flows in my test network. 
however, for the outputifindex value, it just shows as "multiple".

how can i get the individual values for this particular field?

thanks!

The sFlow agent in the switch only reports the egress ports for unicast packets for ingress sampled packets. Non-unicast packets are reported as having multiple egress interfaces, see sFlow Version 5, page 28, "Input/output port information"

https://sflow.org/sflow_version_5.txt

You have two options:
1. Enabling bi-directional sampling (ingress/egress) should give you visibility into egress ports.
2. Enable ingress sampling on all switches. You will then have ingress sampling enabled for each direction for every link. Configuring the network topology allows sFlow-RT to automatically correlate the link data sources, https://sflow-rt.com/topology.php
