class System.​Diagnostics.​Metrics.​Counter<​T>
Assembly: System.Diagnostics.DiagnosticSource
Inheritance: object → Instrument → Instrument<​T> → Counter
Represents an instrument that supports adding non-negative values. For example, you might call <c>counter.Add(1)</c> each time a request is processed to track the total number of requests. Most metric viewers display counters using a rate (requests/sec), by default, but can also display a cumulative total.
