sure, but I guess the loss rate depends of the nature of the traffic.
Packet loss is packet loss. Some applications are more sensitive to it (live video, live voice, for example), while others are less so. However, packet loss always manifests badly if left unchecked.
I guess that having more reports would support the judgements better.
For sure, yes. Any decent NMS can provide a number of data points so you aren't shooting in the dark.
A basic question is : what is the effect on the perceived quality of the customers ?
Depends on the application. Gamers tend to complain the most, so that's a great indicator. Some customers that think bandwidth solves all problems will perceive their inability to attain their advertised contract as a problem, if packet loss is in the way. Generally, other bad things, including unruly human beings :-).
And the relation between that and /5min load is not known to me.
For troubleshooting, being able to have a tighter resolution is more important. 5-minute averages are for day-to-day operations, and long-term planning.
Actually one good indicator of the congestion loss rate are of course the SNMP OutputDiscards.
Curves for queueing delay, link load and discard rate are surprisingly different.
Yes, that then gets into the guts of the router hardware, and it's design. In such cases, that's when your 100Gbps link is peaking and causing packet loss, not understanding that the forwarding chip on it is only good for 60Gbps, for example. Mark.
