jaeger exporter shutdown or force_flush implemented?

[nathanhoult]

I added opentelemetry to a rake task and noticed traces started posting after I added a sleep(10) to at_exit. I added tracer_provider.shutdown but it doesn't block and after looking into the jaeger implementation just returns SUCCESS .

If it helps explain what I am trying to do and always possible I am doing something wrong:

require 'opentelemetry/sdk'
require 'opentelemetry/exporter/jaeger'

OpenTelemetry::SDK.configure do |c|
  c.resource = OpenTelemetry::SDK::Resources::Resource.create(
    'service.name' => 'service1' # Replace with your desired service name
  )
  c.add_span_processor(OpenTelemetry::SDK::Trace::Export::BatchSpanProcessor.new(OpenTelemetry::Exporter::Jaeger::AgentExporter.new(
    host: "localhost",
    port: 6831
  )))
end

tracer_provider = OpenTelemetry::SDK::Trace::TracerProvider.new
MyAppTracer = OpenTelemetry.tracer_provider.tracer('service1')

# Register an at_exit hook
at_exit do
  # Flush and shutdown the tracer
  puts("   shutdown code: #{tracer_provider.shutdown(timeout: 60)}")
  puts("Force flush code: #{tracer_provider.force_flush(timeout: 60)}")
  #sleep(10)
end

task :test do |t|
  MyAppTracer.in_span("#{t}") do |span|
    span.add_attributes({
      "task" => "#{t}"
    })
    trace_id = span.context.trace_id
    puts "#{t} trace ID: #{trace_id.unpack1('H*')}"
    puts "#{t} ran"
  end
end

Thanks in advance for any help.
