public class RichGaugeExporter extends AbstractMetricExporter
Exporter or converter forRichGaugedata to a metric-based back end. Each gauge measurement is stored as a set of related metrics with a common prefix (the name of the gauge), and suffixes that describe the data. For example, a gauge calledfoois stored as[foo.min, foo.max. foo.val, foo.count, foo.avg, foo.alpha]. If theMetricWriterprovided is aMultiMetricRepositorythen the values for a gauge will be stored as a group, and hence will be retrievable from the repository in a single query (or optionally individually).- 从以下版本开始:
- 1.3.0

next
protected Iterable<Metric<?>> next(String group)
从类复制的说明:AbstractMetricExporterGet the next group of metrics to write.- 指定者:
next在类中AbstractMetricExporter- 参数:
group- the group name to write- 返回:
- some metrics to write
groups
protected Iterable<String> groups()
从类复制的说明:AbstractMetricExporterGenerate a group of metrics to iterate over in the form of a set of Strings (e.g. prefixes). If the metrics to be exported partition into groups identified by a String, subclasses should override this method. Otherwise the default should be fine (iteration over all metrics).- 覆盖:
groups在类中AbstractMetricExporter- 返回:
- groups of metrics to iterate over (default singleton empty string)
write
protected void write(String group, Collection<Metric<?>> values)
从类复制的说明:AbstractMetricExporterWrite the values associated with a group.- 指定者:
write在类中AbstractMetricExporter- 参数:
group- the group to writevalues- the values to write
