Metrics of my application

[NaveenTimeDoc]

Hi,
I configured Otel for my ruby on rails application and able to get the traces in jaeger but unable to get the metrics of my application, i could only see basic metrics like below

HELP rails_info Rails application information

TYPE rails_info gauge

rails_info{version="7.1.5.1",ruby="3.3.6"} 1

HELP app_version Application version information

TYPE app_version gauge

app_version{version="dev"} 1

Note: Detailed metrics are collected by OpenTelemetry

Here is my initializer

require "opentelemetry/sdk"
require "opentelemetry/exporter/otlp"
require "opentelemetry/instrumentation/all"
require 'opentelemetry-metrics-sdk'

OpenTelemetry::SDK.configure do |c|
  c.service_name = "timedoc_app"

  c.use_all

  c.add_span_processor(
    OpenTelemetry::SDK::Trace::Export::BatchSpanProcessor.new(
      OpenTelemetry::Exporter::OTLP::Exporter.new(
        endpoint: "http://otel-collector:4318/v1/traces"
      )
    )
  )
end

exporter = OpenTelemetry::SDK::Metrics::Export::ConsoleMetricPullExporter.new
OpenTelemetry.meter_provider.add_metric_reader(exporter)

And here is my otel config

Any suggestions...

Thanks in advance
