千分尺计时器和Spring Boot 2.0.4

我正在尝试使用Spring Boot 2.0.4 +千分尺将指标发送到InfluxDB,但是只有Counter可以工作,而Timer不能。

所以,这是我的依赖项:

...
<dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-influx</artifactId>
        </dependency
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
<dependency>
            <groupId>org.influxdb</groupId>
            <artifactId>influxdb-java</artifactId>
            <version>2.8</version>
        </dependency>
...

使用计数器,正如我所说,一切正常,请参阅:

private final Counter counter = Metrics.counter("my.counter", "my.extra.tag", this.getClass().getCanonicalName());
counter.increment();

但是Timer不起作用,我尝试了@Timed和Timer.sample,它们都不向influxDB发送任何度量。我通过@Service类中的方法对其进行了注释:

@Timed(value = "my.timer", extraTags = { "my.extra.tag", "TimerSomething" })

因此,我尝试将Timer.sample更改为:https://micrometer.io/docs/concepts#_storing_start_state_in_code_timer_sample_code,但没有任何内容发送到influxDB。

这是我配置涌入的属性:

management.endpoints.web.exposure.include: info, health, metrics
management.metrics.export.influx.enabled=true
management.metrics.export.influx.auto-create-db=false
management.metrics.export.influx.batch-size=10000
management.metrics.export.influx.db=my.metrics.db
management.metrics.export.influx.uri=http://xxxxx:8086

编辑1:

我尝试创建一个简单的测试,请参阅:

@RunWith(MockitoJUnitRunner.class)
public class MicrometerTest {

    private final InfluxConfig config = new InfluxConfig() {

        @Override
        public String get(String s) {
            return null;
        }

        @Override
        public Duration step() {
            return Duration.ofSeconds(5);
        }

        @Override
        public boolean autoCreateDb() {
            return false;
        }

        @Override
        public String db() {
            return "mydb";
        }

        @Override
        public String uri() {
            return "http://xxxx:8086";
        }

    };

    private final InfluxMeterRegistry registry = new InfluxMeterRegistry(this.config, Clock.SYSTEM);


    @Test
    public void counter() throws InterruptedException {
        Counter counter = this.registry.counter("my.counter", Tags.of("key", "value"));

        counter.increment();
        TimeUnit.SECONDS.sleep(5);
        TimeUnit.SECONDS.sleep(5);
    }

    @Test
    public void verifica_se_timer_funciona() throws InterruptedException {
        Timer.Sample sample = Timer.start(this.registry);

        TimeUnit.SECONDS.sleep(1);

        Timer timer = this.registry.timer("my.timer", "response", "200");
        sample.stop(timer);
        TimeUnit.SECONDS.sleep(5);
    }
}

计数器工作正常,但计时器不工作。

我怀疑这是this question的副本,但是Timer.Sample的副本。请查看我对问题的回答,以了解阶梯式仪表的工作原理。

我还添加了a test for Timer.Sample以确认其正常工作。


更新:

按照以下注释中的要求,我更新了the sample以使用自动配置的

我确认它有效(至少在Spring Boot Actuator中有效):http://localhost:8080/actuator/metrics/hello.timer

{
  "name" : "hello.timer",
  "description" : null,
  "baseUnit" : "milliseconds",
  "measurements" : [ {
    "statistic" : "COUNT",
    "value" : 1.0
  }, {
    "statistic" : "TOTAL_TIME",
    "value" : 0.225828
  }, {
    "statistic" : "MAX",
    "value" : 0.225828
  } ],
  "availableTags" : [ ]
}


更新2:

FTR我确认它已按以下方式发布到InfluxDB:

> delete from hello_timer 
> select * from hello_timer 
> select * from hello_timer 
name: hello_timer 
time count mean metric_type sum upper 
---- ----- ---- ----------- --- ----- 
1539266391883000000 1 0.54792 histogram 0.54792 0.54792

我遇到了同样的问题,并修复了刚刚在初始化中添加一行的问题:

timer = Metrics.timer("report.execution.time");
timer.record(0, TimeUnit.NANOSECONDS);

看起来很奇怪,但是此后在InfluxDB中成功创建了计时器度量值。
