Monitor Sinatra performance with OpenTelemetry
Sinatra is a powerful and flexible micro web framework built with Ruby. It allows to quickly create web applications in Ruby with minimal effort.
This article explains how you can monitor and optimize Sinatra performance using OpenTelemetry observability framework.
What is OpenTelemetry?
OpenTelemetry is an open-source observability framework hosted by Cloud Native Computing Foundation. It is a merger of OpenCensus and OpenTracing projects.
OpenTelemetry aims to provide a single standard across all types of observability signals such as OpenTemetry tracing, and OpenTelemetry metrics.
OpenTelemetry specifies how to collect and send telemetry data to backend platforms. With OpenTelemetry, you can instrument your application once and then add or change vendors without changing the instrumentation.
OpenTelemetry is available for most programming languages and provides interoperability across different languages and environments.
Sinatra instrumentation
To instrument Sinatra app, you need a corresponding Sinatra OpenTelemetry instrumentation:
gem install opentelemetry-instrumentation-sinatra
If you use bundler, add opentelemetry-instrumentation-sinatra to your Gemfile.
Getting started
To get started, call use with the name of the instrumentation:
require 'uptrace'
require 'opentelemetry-instrumentation-sinatra'
Uptrace.configure_opentelemetry(dsn: '') do |c|
c.use 'OpenTelemetry::Instrumentation::Sinatra
end
Alternatively, you can call use_all to install all available instrumentations:
require 'uptrace'
require 'opentelemetry-instrumentation-sinatra'
Uptrace.configure_opentelemetry(dsn: '') do |c|
c.use_all
end
What is Uptrace?
Uptrace is an open source APM for OpenTelemetry that helps developers pinpoint failures and find performance bottlenecks. Uptrace can process billions of spans on a single server and allows to monitor your software at 10x lower cost.
You can get started with Uptrace by downloading a DEB/RPM package or a pre-compiled Go binary.
What's next?
Next, instrument more operations, for example, database queries and network calls. You can also learn about OpenTelemetry Ruby API to create your own instrumentations.
