<p>A gauge is a metric that represents a single numerical value that can arbitrarily go up and down.
|
|
Gauges are typically used for measured values like temperatures or current memory usage, but also “counts” that can go up and down, like the number of active threads.
|
|
Gauges are modeled as <code><a href="../Classes/Recorder.html">Recorder</a></code> with a sample size of 1 and that does not perform any aggregation.</p>
