Anybody else implement grafana to watch their network utilization and get surprised at how little network traffic there is?

I've started collecting SNMP interface stats on all of my core switches throughout the enterprise and viewing in grafana, and I've been surprised at how relatively low the utilization is on the various infrastructure links.

I'm only querying every minute, so I realize all of my numbers are one minute averages and that the instantaneous peaks are higher. But still, I'm surprised at how little data flows about most of the time.

Anybody else have this experience?
