英文:
Micrometer/Prometheus how to get recorded metric
问题
我目前正在使用`@Timed(value = "data.processing.time")`注解记录方法的执行时间，但我也想读取方法的执行时间数据，并将其与我在属性中设置的方法执行限制进行比较，然后将数据发送到Prometheus，我认为有一种方法可以从MeterRegistry中获取指标，但目前无法理解如何实现，是否有实现的方法？
当前使用的依赖：
'io.micrometer:micrometer-registry-prometheus:1.10.4'
'org.springframework.boot:spring-boot-starter-actuator:2.5.12'
当前用法：
@Bean
public TimedAspect timedAspect(MeterRegistry registry) {
return new TimedAspect(registry);
}
@Timed(value = "data.processing.time")
private boolean process(byte[] data, String ti, Integer priority) {
//do something
}
英文:
I'm currently recording method's execution time using @Timed(value = "data.processing.time") annotation, but I also would love to read the method's execution time data and compare it with the method's execution limit that I want to set in my properties and then send the data to prometheus, I would assume that there is a way to get the metrics out of MeterRegistry, but currently can't get how, is there a way to do so?
Currently used dependancies:
'io.micrometer:micrometer-registry-prometheus:1.10.4'
'org.springframework.boot:spring-boot-starter-actuator:2.5.12'
Current usage:
@Bean
public TimedAspect timedAspect(MeterRegistry registry) {
return new TimedAspect(registry);
}
@Timed(value = "data.processing.time")
private boolean process(byte[] data, String ti, Integer priority) {
//do something
}

这可能会有所帮助，看到更多你的代码，但也许你可以将其记录为直方图 - 就像这样：
methodDuration = Histogram.build()
.name("data_processing_duration")
.register(meterRegistry);
Histogram.Timer timer = methodDuration.startTimer();
timer.observeDuration();
英文:
It would be helpful to see more of your code, but maybe you could record it as a histogram - like this:
methodDuration = Histogram.build()
.name("data_processing_duration")
.register(meterRegistry);
Histogram.Timer timer = methodDuration.startTimer();
timer.observeDuration();

你需要创建一个 @Bean 来定义 TimedAspect。之后，@Timed 注解的工作取决于代理和方法的可见性。根据我所知，使用 JDK 代理，private 方法无法正常工作，所以首先尝试将其改为包私有：
@Timed(value = "data.processing.time")
boolean process(byte[] data, String ti, Integer priority) {
//做一些操作
}
英文:
You need to create a @Bean of TimedAspect. After that @Timed should work depending on the proxy and method visibility. private methods do not work with the JDK proxy as far as I know so fisrt try to make it package-private:
@Timed(value = "data.processing.time")
boolean process(byte[] data, String ti, Integer priority) {
//do something
}
