远程可写存储

remote_write 主要用于可写远程存储配置，主要包含以下参数：

  • url: 访问地址
  • remote_timeout: 请求超时时间
  • write_relabel_configs: 标签重置配置, 拉取到的数据，经过重置处理后，发送给远程存储

其代码结构体为：

  1. // RemoteWriteConfig is the configuration for writing to remote storage.
  2. type RemoteWriteConfig struct {
  3.     URL                 *URL             `yaml:"url,omitempty"`
  4.     RemoteTimeout       model.Duration   `yaml:"remote_timeout,omitempty"`
  5.     WriteRelabelConfigs []*RelabelConfig `yaml:"write_relabel_configs,omitempty"`
  7.     // We cannot do proper Go type embedding below as the parser will then parse
  8.     // values arbitrarily into the overflow maps of further-down types.
  9.     HTTPClientConfig HTTPClientConfig `yaml:",inline"`
  11.     // Catches all undefined fields and must be empty after parsing.
  12.     XXX map[string]interface{} `yaml:",inline"`
  13. }

一份完整的配置大致为:

  1. # The URL of the endpoint to send samples to.
  2. url: <string>
  4. # Timeout for requests to the remote write endpoint.
  5. [ remote_timeout: <duration> | default = 30s ]
  7. # List of remote write relabel configurations.
  8. write_relabel_configs:
  9.   [ - <relabel_config> ... ]
  11. # Sets the `Authorization` header on every remote write request with the
  12. # configured username and password.
  13. basic_auth:
  14.   [ username: <string> ]
  15.   [ password: <string> ]
  17. # Sets the `Authorization` header on every remote write request with
  18. # the configured bearer token. It is mutually exclusive with `bearer_token_file`.
  19. [ bearer_token: <string> ]
  21. # Sets the `Authorization` header on every remote write request with the bearer token
  22. # read from the configured file. It is mutually exclusive with `bearer_token`.
  23. [ bearer_token_file: /path/to/bearer/token/file ]
  25. # Configures the remote write request's TLS settings.
  26. tls_config:
  27.   [ <tls_config> ]
  29. # Optional proxy URL.
  30. [ proxy_url: <string> ]

注意： remote_write 属于试验阶段，慎用，因为在以后的版本中可能发生改变。
