In today’s rapidly evolving technological landscape, the need for comprehensive monitoring and observability solutions has never been more critical. As applications become more complex, distributed, and dynamic, traditional monitoring tools fall short of providing the necessary insights. Think about the scale at which powerful applications like Google, WhatsApp, Facebook, TikTok, etc. are used across the world, see how complex it is to monitor or observe all that’s going on within the applications.
Enter OpenTelemetry, a powerful and open-source solution that’s transforming the world of observability. In this article, I’ll explore what OpenTelemetry is, delve into its data and capabilities, and understand how querying observability data with New Relic Query Language (NRQL) on the New Relic dashboard can revolutionize the way you monitor and optimize your systems.
What is OpenTelemetry?
OpenTelemetry is a collection of tools, APIs, and SDKs designed for the instrumentation of software to create and collect telemetry data. Telemetry data includes traces, metrics, and logs that provide visibility into the performance and behavior of your applications. As an open-source initiative under the Cloud Native Computing Foundation (CNCF), OpenTelemetry aims to provide a single set of standards and practices for collecting distributed traces and metrics.
Understanding OpenTelemetry Data
OpenTelemetry data can be broadly categorized into three types:
Traces: Represent the journey of a request as it flows through a distributed system. Each trace is composed of spans, which are individual units of work within the trace. Traces help in understanding the lifecycle of a request and identifying performance bottlenecks.
Metrics: Quantitative data that measures the performance and health of your application. Common metrics include CPU usage, memory consumption, request count, error rates, and latency.
Logs: Immutable records of events that provide context to traces and metrics. Logs are crucial for diagnosing issues and understanding system behavior during specific time periods.
Monitoring and Observability with OpenTelemetry
Observability is the practice of instrumenting systems to provide insights into their internal states, allowing engineers to monitor, diagnose, and optimize their applications. OpenTelemetry simplifies this by providing a standardized way to collect telemetry data from various sources, regardless of the programming language or framework used.
With OpenTelemetry, you can instrument your code to automatically collect traces, metrics, and logs. This data is then exported to observability platforms like New Relic, where it can be visualized, analyzed, and queried.
Querying OpenTelemetry Data with NRQL on New Relic Dashboard
New Relic provides a powerful query language called NRQL (New Relic Query Language) that allows you to query and visualize telemetry data collected by OpenTelemetry. NRQL is similar to SQL but designed specifically for querying telemetry data.
Here’s an example of how you can query OpenTelemetry data using NRQL:
SELECT average(duration) FROM Span WHERE name = 'transactionName' TIMESERIES

In this query, we’re selecting the average duration of spans with the name ‘transactionName’ and visualizing the results as a time series. This helps in understanding the performance trends of specific transactions over time.
Why is OpenTelemetry Important?
Standardization: OpenTelemetry provides a standardized way to collect telemetry data, reducing the need for multiple, vendor-specific instrumentation libraries.
Interoperability: As an open-source project, OpenTelemetry integrates with various observability platforms, ensuring that you’re not locked into a single vendor.
Comprehensive Insights: By collecting traces, metrics, and logs in a unified manner, OpenTelemetry offers a holistic view of your system’s performance and health.
Flexibility: OpenTelemetry supports a wide range of programming languages and frameworks, making it suitable for diverse tech stacks.
The Future is Open
The future of observability is undeniably open. OpenTelemetry’s open-source nature encourages collaboration and innovation, leading to faster adoption and continuous improvement. As more organizations embrace OpenTelemetry, the ecosystem will expand, resulting in richer integrations, better tooling, and more robust community support.
Advantages for Data Experts
Unified Data Collection: Data experts can leverage OpenTelemetry to collect and correlate traces, metrics, and logs from a single source, simplifying data management and analysis.
Enhanced Visibility: With comprehensive telemetry data, data experts can gain deeper insights into system performance, identify anomalies, and optimize applications more effectively.
Cost Efficiency: By using an open-source solution like OpenTelemetry, organizations can reduce costs associated with proprietary monitoring tools while still achieving top-tier observability.
Innovation and Collaboration: OpenTelemetry’s community-driven development fosters innovation and collaboration, allowing data experts to stay ahead of the curve with the latest advancements in observability.
I look forward to helping your organization improve it’s systems efficiency.
