+ | |Total traffic|Total traffic bandwidth used by a User or App| | ||
+ | |Download traffic| Download bandwidth used by per User/App. The Download direction is metered when the flow source IP is an external IP address and the destination-IP is internal. Internal IPs belong to the Home Network configured in Trisul| | ||
+ | |Upload traffic| per-User bandwidth out of home network to external| | ||
+ | |Internal traffic| per-User bandwidth where both the source and destination are inside the home network| | ||
+ | |Transit traffic| where both source and destination are outside the home network. You will typically not find data here in normal enterprise environments| | ||
