The OpenTelemetry Collector is a vendor-agnostic implementation for receiving, processing, and exporting telemetry data across traces, metrics, and logs. Written in Go, it eliminates the need to run and maintain multiple separate agents or collectors by providing unified support for popular open-source telemetry formats such as Jaeger and Prometheus, while enabling export to both open-source and commercial backends. The project is built against OTLP protocol v1.10.0, which is considered stable.
The collector's core objectives emphasize usability with reasonable default configurations and out-of-the-box functionality, performance under varying loads, observability as an exemplar service, extensibility without modifying core code, and unified deployment as either an agent or collector. The codebase is deployable in multiple configurations and supports a comprehensive range of telemetry data types through its receiver, processor, and exporter architecture.
The project maintains active community involvement through the OpenTelemetry Collector SIG, which operates a dedicated Slack channel at #otel-collector on the CNCF workspace and conducts weekly video meetings rotated across three time slots to accommodate global participation. The community emphasizes that GitHub serves as the source of truth for all decisions, with Slack and video calls used for synchronous discussion that must be documented in relevant GitHub issues.
The repository's maintainer structure includes five active maintainers from organizations including Honeycomb, Snowflake, Splunk, Dynatrace, and DataDog, with seven approvers and three active triagers. The project actively seeks additional contributors for the triager role. The Go version support policy aligns with the Go team's supported minor versions, with the first release after a new Go minor version adding build and test steps for that version while removing support for versions two minor versions behind.
The project implements security best practices and includes internal telemetry capabilities for monitoring the collector itself. Container images are signed using sigstore cosign starting from release v0.95.0, allowing users to verify image authenticity. The codebase maintains build status monitoring, Go report card tracking, and codecov coverage reporting as part of its quality assurance practices.
