Opentelemetry Php
OpenTelemetry PHP is a standard-compliant observability framework designed to instrument applications for the collection and export of telemetry data. It provides a comprehensive suite of tools for capturing traces, metrics, and logs, enabling developers to monitor operational behavior and system performance in real time.
The project distinguishes itself through an interface-driven plugin architecture that allows for the modular configuration of exporters, processors, and samplers. To maintain performance in production environments, it supports the use of native binary extensions for data serialization and employs asynchronous batch processing to minimize the overhead associated with transmitting telemetry signals.
The framework covers a broad range of observability capabilities, including distributed request tracing and context propagation to link operations across service boundaries. It utilizes runtime instrumentation hooks to capture performance data automatically, while supporting standardized export protocols such as HTTP and gRPC to ensure compatibility with diverse monitoring backends.
Features
- PHP Instrumentation Toolkits - Provides a collection of tools for capturing and exporting traces, metrics, and logs from PHP applications to observability backends.
- Distributed Tracing - Provides a framework for recording request paths across service boundaries to visualize performance and identify failures in complex system architectures.
- Tracing Context Propagation - Implements mechanisms for injecting and extracting distributed tracing headers across network boundaries to maintain request correlation.
- Runtime Instrumentation - Injects observation logic into application code at execution time to capture performance metrics and events without requiring manual code changes.
