远程可读存储

remote_read 主要用于可读远程存储配置，主要包含以下参数：

  • url: 访问地址
  • remote_timeout: 请求超时时间

其代码结构体为：

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

一份完整的配置大致为:

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

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