What is Observability?

Observability is a broad term that refers to the ability to see into an opaque system by inferring the internal state of that system based on its outputs.

Observability can help you understand your multi-layer applications in depth. What's slow, broken, or in need of maintenance? Observability allows your whole team to optimize bandwidth by easily seeing not only when a problem is occurring but why.

How does Monitoring differ from Observability?

Monitoring is used to monitor your systems performance and discover the particular areas that you need to pay attention to. Observability on the other hand comes from control theory - giving you the insight to see how each piece of your system fits together so you can determine what to look at when it matters most.

Distributed Tracing

Observability leverages telemetry data to provide development teams insights into the current state of their engineering stack. Distributed tracing involves collecting traces, logs, events, and metrics across all applications within your stack, including the browser, and provides the ability to observe a transaction and its performance details from start to finish in order understand what happened within that transaction as it was handled by each application.

What is OpenTelemetry?

OpenTelemetry is an open source project that has been gaining traction in the past few years. It provides a unified standard for telemetry data, including metrics, traces, and logs.

OpenTelemetry is the future of the full-stack observability market because it allows companies to be vendor neutral. With the collection of data switching to open source and being widely available, the question now becomes where do you send your data and who do you trust to provide actionable insights on that data?

What does full-stack observability with OpenTelemetry do for you and your teams?

OpenTelemetry provides a standard method of collecting and transferring datato a target system, no longer constraining your team to a specific language . Your team will no longer have to choose tools based on your programming language or the way your application was built. With OpenTelemetry collecting and translating your data into a universal language, you can choose tools that will provide you real, actionable insights.

OpenTelemetry in Javascript

You can use OpenTelemetry to unify all of your telemetry data of your front and back-end applications across both mobile and desktop devices. Configuring OpenTelemetry and distributed tracing for JavaScript is extremely straight forward. Once set-up OpenTelemetry will provide a spectrum of data points that you can send to an Observability tool. Leveraging an observability tool, such as Scout, will interpret complex telemetry data and provide actionable insights needed to make decisions regarding your tech stack.

OpenTelemetry in Ruby

You can use OpenTelemetry in your Ruby app to collect all metrics, traces, and logs and ingest that data into a single source of truth! You can configure OpenTelemetry in Ruby with just a few simple steps, and either analyze yourself or send your telemetry data to a vendor such as Scout, allowing you to gain better insights into your stack.
