Module telemetry::keyed [−] [src]

Definition of keyed histograms, for data in a set known dynamically.

Definition of keyed (aka "dynamic family of") histograms.

Keyed histograms represent measures on a set of entities known only at runtime, e.g. plug-ins, user scripts, etc. They are also slower, more memory-consuming and less type-safe than Plain histograms, so you should prefer the latter whenever possible.
