Augtera detects TCP SACK options through sFlow which is an indication that an issue is emerging. Further inspection shows fabric interfaces are dropping packets, because of how traffic is being load balanced. Similarly, an underlay could be impacting a SD-WAN overlay. Instead of focusing on which servers are impacted, in this use case, the focus is the applications impacted.
