OpenTelemetry
OpenTelemetry is an open-source observability framework for generating, collecting, and exporting telemetry data such as metrics, logs, and traces.
Profile
Provides open-source tools to monitor software performance by collecting and analyzing system metrics, logs, and transaction traces.
OpenTelemetry is an open-source observability framework for generating, collecting, and exporting telemetry data such as metrics, logs, and traces. It emerged from the merger of OpenTracing and OpenCensus projects under the Cloud Native Computing Foundation (CNCF) umbrella, graduating to a top-level project in 2021. The framework provides vendor-neutral APIs, SDKs, and tools to instrument software performance and behavior, with adoption accelerating in financial services, e-commerce, and cloud-native infrastructure.
A 2025 survey revealed that 65% of users deploy more than 10 Collector instances, with Kubernetes remaining the dominant deployment environment (81%) while VM usage grew significantly to 51%. The payments observability market leveraging OpenTelemetry was valued at $2.8 billion in 2025, projected to reach $9.6 billion by 2034. Recent developments include expanded use of connectors like datadogconnector and processors like transformprocessor, though configuration complexity remains a top user concern. The project maintains strong community involvement through SIGs and contributor programs, with commercial vendors building managed services atop its open core.

Frequently Asked Questions
What is OpenTelemetry?
OpenTelemetry is an open-source observability framework for collecting metrics, logs, and traces from software systems. It provides vendor-neutral tools to monitor application performance, born from the merger of OpenTracing and OpenCensus. The CNCF-graduated project is widely adopted in cloud-native environments.
How does OpenTelemetry compare to proprietary observability tools?
OpenTelemetry offers vendor-neutral instrumentation, avoiding lock-in to specific monitoring platforms. Unlike proprietary suites, it provides standardized APIs for metrics, logs, and traces. However, some commercial tools offer tighter integration out-of-the-box, while OpenTelemetry requires more configuration.
Why use OpenTelemetry with Kubernetes?
81% of OpenTelemetry users deploy it in Kubernetes environments, as the framework excels at monitoring distributed microservices. Its Collector handles auto-instrumentation of containerized workloads, making it ideal for cloud-native applications. VM usage is growing too, reaching 51% adoption.
How do financial services use OpenTelemetry?
Banks use OpenTelemetry for transaction monitoring, while payment providers apply it to fraud detection. The payments observability market using OpenTelemetry was valued at $2.8 billion in 2025. It helps track money flows across distributed systems with standardized tracing.
What are OpenTelemetry's main components?
OpenTelemetry provides APIs for instrumentation, SDKs for language-specific implementations, and Collectors for processing telemetry data. Key elements include connectors like datadogconnector and processors like transformprocessor. The framework supports metrics, logs, and traces through a unified approach.
What challenges do users face with OpenTelemetry?
Configuration complexity is the top user concern, per 2025 surveys. Performance overhead can impact high-throughput systems like payment processing. While community support is strong, some teams struggle with the learning curve compared to turnkey commercial observability solutions.
