| <p>A <a class="el" href="classimpala_1_1SimpleMetric.html">SimpleMetric</a> has a value which is a simple primitive type: e.g. integers, strings and floats. It is parameterised not only by the type of its value, but by both the unit (e.g. bytes/s), drawn from TUnit and the 'kind' of the metric itself. The kind can be one of: 'gauge', which may increase or decrease over time, a 'counter' which is increasing only over time, or a 'property' which is not numeric. SimpleMetrics return their current value through the <a class="el" href="classimpala_1_1SimpleMetric.html#aee1b3c3e9b4d8f5bd9c8e199cf742572" title="Returns the current value, updating it if necessary.
