方法名：gauges

Registry.gauges介绍

[英]Returns a stream of all registered gauges. This operation is mainly used for testing as a convenient way to get an aggregated value. For example, to generate a summary of the values for all gauges with name "foo":

DoubleSummaryStatistics valueSummary = r.gauges() 
.filter(Functions.nameEquals("foo")) 
.collect(Collectors.summarizingDouble(Gauge::value)); 
double sum = (double) valueSummary.getSum();

[中]返回所有注册仪表的流。此操作主要用于测试，作为获取聚合值的方便方法。例如，要生成名为“foo”的所有仪表值的摘要，请执行以下操作：

DoubleSummaryStatistics valueSummary = r.gauges() 
.filter(Functions.nameEquals("foo")) 
.collect(Collectors.summarizingDouble(Gauge::value)); 
double sum = (double) valueSummary.getSum();

 assertEquals(3, registry.counters().count());
 assertEquals(0, registry.timers().count());
 assertEquals(1, registry.gauges().count());
 assertEquals(0, registry.distributionSummaries().count());
 assertEquals(1, registry.counter(id.withTag(Statistic.count)).count());
 assertEquals(42, registry.counter(id.withTag(Statistic.totalTime)).count());
 assertEquals(42 * 42, registry.counter(id.withTag(Statistic.totalOfSquares)).count());
 assertEquals(42.0, registry.maxGauge(id.withTag(Statistic.max)).value());
