public abstract class Instrument

Object
Instrument

One named measurement: a counter, a gauge or a histogram.

Created once through Metrics and kept – the build’s generated code holds each in a static field – so recording a value never looks anything up.

Fields

`public static final int COUNTER = 0`
`public static final int UP_DOWN_COUNTER = 1`
`public static final int GAUGE = 2`
`public static final int HISTOGRAM = 3`

Methods

`public` `String getName()`
`public` `String getDescription()`
`public` `String getUnit()`
`public int getKind()`	`COUNTER`, `UP_DOWN_COUNTER`, `GAUGE` or `HISTOGRAM`.
`public abstract` `List points()`	The current points, each a map with `attributes` (a map, possibly empty) and either `value` or, for a histogram, `count`, `sum`, `min`, `max`, `bounds` and `buckets`.
