如何将自定义属性添加到opentelemetry hostmetricsReceiver

Question

我正在使用opentelemetry collector contermetmetricsReceiver https://github.com/open-telemetry/opentelemetry-collector-collector-contrib/tree/main/main/receiver/hostmetricsreceiver

我对这一过程特别感兴趣，所以我的Otel-Config看起来像这样：

receivers:
  hostmetrics:
    collection_interval: 1m
    scrapers:
      process:

processors:
  batch:

exporters:
  logging:
    loglevel: debug

service:
  pipelines:
    metrics:
      receivers: [ hostmetrics ]
      exporters: [ logging ]

现在，当前的配置为我提供了每个过程的以下资源级别属性：

        "attributes": [
          {
            "key": "process.pid",
            "value": {
              "intValue": "1"
            }
          },
          {
            "key": "process.executable.name",
            "value": {
              "stringValue": "api-server"
            }
          },
          {
            "key": "process.executable.path",
            "value": {
              "stringValue": "/bin/bash"
            }
          },
          {
            "key": "process.command",
            "value": {
              "stringValue": "/bin/bash"
            }
          },
          {
            "key": "process.command_line",
            "value": {
              "stringValue": "/bin/bash /usr/bin/api-server start"
            }
          },
          {
            "key": "process.owner",
            "value": {
              "stringValue": "root"
            }
          }
        ]

现在，我们要说，我想要要在此处添加过程启动时间作为新属性。我该怎么做？

我读过 https://github.com/open-telemetry/opentelemetry-collector-collector-contrib/tree/main/main/processor/attributesprocessor 和 https://github.com/open-telemetry/opentelemetry-collector-collector-contrib/tree/main/main/main/receiver/hostmetreicsreceiver

但是，我想这些处理器只能帮助我添加具有固定的或静态值。

我可以将这些处理器用于我的用户酶吗？ 如何在现有接收器中添加此类属性？
