Counter¶

A Counter is used to measure the rate at which some event is occurring. Considering a simple queue, Counters could be used to measure things like the rate at which items are being inserted and removed.

Counters are reported to the backend as a rate-per-second. This makes it much easier to reason about the measurement and allows for aggregating the counter across instances.

In Atlas, the :per-step operator can be used to convert them back into a count-per-step on a graph.
