Spring引导千分尺分层度量命名空间级联

Question

我有一个Spring Boot Java应用程序，正在向一个分层的Graphite度量系统发送度量。我在使用管理层。指标。出口石墨标记为前缀，并将主机和应用程序映射为前缀“我的指标”。然后，我有一个名称空间<代码>jvm的度量。记忆力已提交，但度量名称空间将作为主机进行连接。应用程序。JVMMORYCOMMITED* 。所以它代替了点（“.”）在metric名称空间中，并对名称空间的以下部分进行camelcusing。

应用属性<代码>管理。指标。出口石墨标记为前缀=[主机，应用程序]

标记作为前缀的自定义程序。

    @Bean
    public MeterRegistryCustomizer<MeterRegistry> commonTags() {
        return r -> r.config().commonTags("host", "localhost", "app", "app");
    }

当我看着/执行器/指标/jvm。记忆力提交的endpoint我看到以下内容：

  "name": "jvm.memory.committed",
  "description": "The amount of memory in bytes that is committed for the Java virtual machine to use",
  "baseUnit": "bytes",
  "measurements": [
    {
      "statistic": "VALUE",
      "value": 759701504
    }
  ],
  "availableTags": [
    {
      "tag": "area",
      "values": [
        "heap",
        "nonheap"
      ]
    },
    {
      "tag": "app",
      "values": [
        "app"
      ]
    },
    {
      "tag": "host",
      "values": [
        "localhost"
      ]
    },
    {
      "tag": "id",
      "values": [
        "G1 Old Gen",
        "CodeHeap 'non-profiled nmethods'",
        "G1 Survivor Space",
        "Compressed Class Space",
        "Metaspace",
        "G1 Eden Space",
        "CodeHeap 'non-nmethods'"
      ]
    },
  ]
}

但是，当发送度量时，度量名称已从*更改。jvm。记忆力已promise* 至<代码>*。JVMMORYCOMMITED* 。如何以点表示法保留度量名称空间？

请参见以下tcpdump输出：

I think the problem is that I'm using tags, but in a Hierarchical metrics system, but I can't figure out how to configure it properly. I can't seem to find my folly.

Answer 1

Graphite使用Hiree icalNameMapper将度量名称和标签转换为分层字符串。

看见https://micrometer.io/docs/registry/graphite#_hierarchical_name_mapping

我不确定为什么您的映射器会将您的度量名称缩放为camelC，但您可以在构建自己的GraphiteMeter注册表并对它们的生成方式进行微调控制时设置Hi分层NameMapper。
