如何以编程方式从 spring-boot-actuator 获取指标?

我们在生产中有一个 spring 应用程序.它不是 Spring-boot.我发现这篇文章关于如何使用 spring-非弹簧启动应用程序中的启动执行器.

we have a spring application in production. It is NOT Spring-boot. I found this post on how to use spring-boot-actuator in a non-spring-boot application.

但是，我们的要求是聚合来自/metrics 端点的数据并对其进行一些分析并报告状态指示器.

However, the requirement for us is to aggregate the data from /metrics endpoint and do some analytics on it and report a status indicator.

例如，我们可能会使用堆参数，例如{"heap.committed":480768,"heap.init":262144,"heap.used":294461,"heap":3728384,"threads.peak":37} 表示状态应用程序 - 致命、警告或健康.

For eg, we might use heap parameter such as {"heap.committed":480768,"heap.init":262144,"heap.used":294461,"heap":3728384,"threads.peak":37} to indicate the status of the application - FATAL, WARN or HEALTHY.

这只是一个例子.我们的要求比较复杂.事实上，我们已经有一个 status endpoint，我们想在其中添加更多信息(基于来自 /metrics 和 /health 端点的数据spring-boot-actuator).

This is just an example. our requirement is more complex. In-fact, we already have a status endpoint where we want to add more info (based on data from /metrics and /health endpoints of spring-boot-actuator).

我想实现的一种方法是在应用程序中对 /metrics 和 /health 进行 REST 调用，收集数据，聚合它们并返回响应.我不认为这是推荐的方式.

One way I am thinking of acheiving this is making REST call to /metrics and /health with-in the application, collect the data, aggregate them and return the response. I don't think it is a recommended way.

如果有一个可以直接提取这些参数的 bean，我会自动装配它并在需要时即时计算它们.(事实上​​，我会安排定期计算).

If there is a bean where I could extract these parameters directly, I would autowire it and calculate them on the fly as and when needed. (In fact, I will schedule to calculate periodically).

我对从 /metrics 返回的所有属性感兴趣.同时我也对 /health 中的以下内容感兴趣.

I am interested in all the attributes returned from /metrics. while I am also interested in the following from /health.

{"diskSpace":{"status":"UP","free":386186194944,"threshold":10485760}}

我应该自动装配哪些 bean 并免费获得这些属性！

what beans should I autowire and get these attributes for free!

谢谢

这个帖子有@自动装配的 MetricRepository.但出于某种原因，它只返回自定义计数器属性.它不返回堆、内存信息等例如:报告指标 counter.calls.get_greeting=4报告指标 counter.calls.get_greeting.1=1报告指标 counter.calls.get_greeting.2=1报告指标 counter.calls.get_greeting.3=1报告指标 counter.calls.get_greeting.4=1报告指标 counter.status.200.greeting.number=4报告指标 counter.status.404.star-star=1

This post has @Autowired MetricRepository. But for some reason, it returning only the custom counter properties. It is NOT returning heap, memory info etc Eg: Reporting metric counter.calls.get_greeting=4 Reporting metric counter.calls.get_greeting.1=1 Reporting metric counter.calls.get_greeting.2=1 Reporting metric counter.calls.get_greeting.3=1 Reporting metric counter.calls.get_greeting.4=1 Reporting metric counter.status.200.greeting.number=4 Reporting metric counter.status.404.star-star=1
