Summary

A counter is a total since start; the load “right now” is shown by rate(…[1m]), the total over a window by increase.
A selector in curly braces picks series by labels, sum by adds them up and keeps the labels you need.
a / b divides series with the same labels; a > threshold comparison keeps only the series above the threshold.
How much traffic the machine receives right now is rate(node_network_receive_bytes_total[1m]): about 200,000 bytes per second while the counter is in the hundreds of megabytes.
