metrics 用法

	@Autowired
	private MeterRegistry registry;
	private Counter counter;
	private DistributionSummary summary;
	
	//private Gauge gauge;
	private AtomicDouble gaugeDouble;
	
	
	@PostConstruct
	private void init(){
		counter = registery.counter("cnt_test","tagName","tagValue");
		summary = registery.summary("sum_test","tagName","tagValue");
		gaugeDouble = register.gauge("gauge_test",initTag("tagName","tagValue"),new AtomicDouble(0));
	}
	
	public void test(){
		count.increment();
		sumary.record(100);
		gaugeDouble.set(10.1);
	}
	
	private List initTag(String tagName, String tagValue) {
		 ArrayList list = new ArrayList() {};
		 list.add(new ImmutableTag(tagName, tagValue));
		 return list;
	}

prometheus 配置

配置文件名 prometheus.yml ，
增加如下配置项：

- job_name: 'springboot'
	scrape_interval: 5s
	metrics_path: /prometheus
	static_configs:
	- targets: ['127.0.0.1:8080']

grafana 的配置

增加变量
label_values(cnt_test,tagName) 抽取所有tagValue
