|Metric name, unit, and type |Description |Metric tags

// New row
|`queue_requests_per_second`

Metric unit: dimensionless

Metric type: gauge
|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.

// New row
|`queue_proxied_operations_per_second`

Metric unit: dimensionless

Metric type: gauge
|Number of proxied requests per second.

Formula: `stats.ProxiedRequestCount / r.reportingPeriodSeconds`

`stats.ProxiedRequestCount` is calculated directly from the networking `pkg` stats for the given reporting duration.
|

// New row
|`queue_average_concurrent_requests`

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.
