It's great to monitor packet loss, latency, pps, e.t.c. But packet loss at 10% link utilization is not a foreign occurrence. No amount of bandwidth upgrades will fix that.

you could easily have 10% utilization and see packet loss due to insufficient bandwidth if you have egress << ingress and proportionally low buffering, e.g. UDP or iSCSI from a 40G/100 port with egress to a low-buffer 1G port. This sort of thing is less likely in the imix world, but it can easily happen with high capacity CDN nodes injecting content where the receiving port is small and subject to bursty traffic. Nick
