This complements groupByNodes which takes a list of nodes that must match in each group. If regex is used, following special replacement patterns are supported: x(t) == x(t-1)+random()-0.5, and x(0) == 0. See querying tagged series for more detail. @gerrickw Yeah. This would only display interfaces which has a peak throughput higher than 1000 packets/min.
