ekg- Remote monitoring of processes

Safe HaskellNone



This module defines a type for mutable, integer-valued counters. Counters are non-negative, monotonically increasing values and can be used to track e.g. the number of requests served since program start. All operations on counters are thread-safe.

N.B. This module exists to maintain backwards compatibility with older versions of this library. New code should use the System.Metrics.Counter module from the ekg-core package instead.



data Counter

A mutable, integer-valued counter.

inc :: Counter -> IO ()

Increase the counter by one.

add :: Counter -> Int64 -> IO ()

Add the argument to the counter.
