Agent Config Go

Agent config holds all the configuration settings for the Hypertrace Go Agent.

Getting Started

// loads the config from the config file tbd.json and env vars
cfg := config.Load()

// overrides statically the service name
cfg.ServiceName = config.String("myservice")
cfg.DataCapture.HTTPHeaders.Request = config.Bool(true)

Values can also be overriden by the environment variables, e.g. HT_DATA_CAPTURE_HTTP_HEADERS_RESPONSE=false. You can check a list of the supported environment variables here

The location for the config file can also be overriden by passing the path in HT_CONFIG_FILE environment variable or you can set the location in code by using

// loads the config from the specified file and env vars
cfg := config.LoadFromFile("path/to/file.yml")
...

Supported formats for config files are YAML and JSON.

Default Values

All default values are defined in the defaults.go, everything else will be default to zero values.

Loading for existing config

Sometimes the user can choose to populate the config object and then load the config values from environment variables. In such case one can run:

cfg := &config.AgentConfig{}
cfg.ServiceName = config.String("myservice")
cfg.DataCapture.HTTPHeaders.Request = config.Bool(true)

cfg.LoadFromEnv()
