-|Number of requests per second that hit the queue proxy.

-Formula: `stats.RequestCount / r.reportingPeriodSeconds`
-
-`stats.RequestCount` is calculated directly from the networking `pkg` stats for the given reporting duration.

-Metric unit: dimensionless

-Metric type: gauge
-a|Number of requests currently being handled by this pod.
-
-Average concurrency is calculated at the networking `pkg` side as follows:
-
-* When a `req` change happens, the time delta between changes is calculated. Based on the result, the current concurrency number over delta is computed and added to the current computed concurrency. Additionally, a sum of the deltas is kept.
-+
-Current concurrency over delta is computed as follows:
-+
-`global_concurrency` × delta
-
-* Each time a reporting is done, the sum and current computed concurrency are reset.
-
-* When reporting the average concurrency the current computed concurrency is divided by the sum of deltas.
-
-* When a new request comes in, the global concurrency counter is increased. When a request is completed, the counter is decreased.
