Adds LightStep tracing support for gruf 2.0.0+.
gem 'gruf-lightstep'Then in an initializer or before use, after loading gruf:
require 'gruf/lightstep'You can use the following ENV vars to configure lightstep:
| Name | Description |
|---|---|
| LIGHTSTEP_ACCESS_TOKEN | LightStep access token, if used in your satellites |
| LIGHTSTEP_COMPONENT_NAME | The name of your service |
| LIGHTSTEP_HOST | The host of your lightstep satellites |
| LIGHTSTEP_PORT | The port of your lightstep satellites |
See more configuration here: https://github.com/bigcommerce/bc-lightstep-ruby#environment-config
In your gruf initializer:
Gruf.configure do |c|
c.interceptors.use(Gruf::Lightstep::ServerInterceptor)
endIt comes with a few more options as well:
| Option | Description | Default |
|---|---|---|
| allowlist | An array of parameter key names to log to lightstep. E.g. [uuid kind] |
[] |
| ignore_methods | An array of method names to ignore from logging. E.g. ['namespace.health.check'] |
[] |
It's important to maintain a safe allowlist should you decide to log parameters; gruf does no parameter sanitization on its own. We also recommend do not allowlist parameters that may contain very large values (such as binary or json data).
To automatically propagate the trace context outbound, in your Gruf clients, pass the client interceptor
to your Gruf::Client initializer:
Gruf::Client.new(
service: MyService,
client_options: {
interceptors: [Gruf::Lightstep::ClientInterceptor.new]
}
