Ruby - Aspecto

Aspecto::OpenTelemetry
This gem is a distribution of OpenTelemetry pre-configured to use all available instrumentations and export trace data to Aspecto.
Installation

$ gem install aspecto-opentelemetry
Or, if you use bundler, include aspecto-opentelemetry in your Gemfile.
Usage
Rails Applications
Add this code to a new file aspecto.rb under config/initializers/:
# config/initializers/aspecto.rb
require 'aspecto/opentelemetry'
​
Aspecto::OpenTelemetry::configure do |c|
  c.service_name = '<YOUR_SERVICE_NAME>'
  c.aspecto_auth = '<YOUR_ASPECTO_TOKEN>'
  # c.sampling_ratio = 1.0 # [optional]: defaults to 1.0, use aspecto app to configure remotely
end
Ruby Applications
Add this code after your require other gems:
require 'aspecto/opentelemetry'
​
Aspecto::OpenTelemetry::configure do |c|
  c.service_name = '<YOUR_SERVICE_NAME>'
  c.aspecto_auth = '<YOUR_ASPECTO_TOKEN>'
  # c.env = '<CURRENT_ENVIRONMENT>' # [optional]: automatically detected for rails and sinatra
  # c.sampling_ratio = 1.0 # [optional]: defaults to 1.0, use aspecto app to configure remotely
end
Shutdown
Call this function when your application shuts down
Aspecto::OpenTelemetry::shutdown
Configuration
You can set configuration via environment variables or via code. Values set in code takes precedence. The only required config options are aspecto_auth and service_name.

Environment Variable
Type
Default
Description
aspecto_auth
ASPECTO_AUTH
UUID string
-
Aspecto's API key for authentication
service_name
OTEL_SERVICE_NAME
string
-
Name of the service which is sending telemetry
env
ASPECTO_ENV
string
Extracted from Rails or Sinatra if used
Deployment environment: production / staging / development, etc.
log_level
OTEL_LOG_LEVEL
string
ERROR
ERROR / WARN / INFO, etc.
sampling_ratio
ASPECTO_SAMPLING_RATIO
float
1.0
How many of the traces starting in this service should be sampled. set to number in range [0.0, 1.0] where 0.0 is no sampling, and 1.0 is sample all
require_config_for_traces
ASPECTO_REQUIRE_CONFIG_FOR_TRACES
boolean
false
When true, the SDK will not trace anything until remote sampling configuration arrives (few hundreds ms). Can be used to enforce sampling configuration is always applied, with the cost of losing traces generated during service startup
otel_exporter_otlp_traces_endpoint
OTEL_EXPORTER_OTLP_TRACES_ENDPOINT

extract_b3_context
ASPECTO_EXTRACT_B3_CONTEXT
boolean
false
Set to true when the service receives requests from another instrumented component that propagate context via B3 protocol multi or single header. For example: Envoy Proxy, Ambassador and Istio
inject_b3_context_single_header
ASPECTO_INJECT_B3_CONTEXT_SINGLE_HEADER
boolean
false
Set to true when the service send traffic to another instrumented component that propagate context via B3 single header protocol
inject_b3_context_multi_header
ASPECTO_INJECT_B3_CONTEXT_MULTI_HEADER
boolean
false
Set to true when the service send traffic to another instrumented component that propagate context via B3 multi header protocol. For example: Envoy Proxy, Istio
