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.
- Instrumentation Libraries - Injects hooks into application logic to automatically or manually capture performance data and operational events during runtime execution.
- Application Observability - Injects hooks into application logic to automatically or manually capture performance data and operational events during runtime execution.
- Application Performance Monitoring - Captures and exports metrics and logs to external observability backends to gain visibility into system health and operational behavior.
- Distributed Tracing Systems - Records the path of requests across multiple services to visualize performance bottlenecks and identify failures within complex system architectures.
- Telemetry Exporters - Pushes internal performance metrics and logs to third-party observability platforms using standard protocols.
- Request Tracing - Provides utilities for monitoring and visualizing the lifecycle of network requests through application layers.
- Telemetry Data Collection - Gathers traces, metrics, and logs from application execution to centralize observability data.
- Request Context Propagation - Maintains trace and span information across service boundaries to ensure that requests remain linked throughout their entire lifecycle.
- Observability Framework Implementations - Provides a standard-compliant implementation for instrumenting application code to monitor operational behavior and system performance in real time.
- Standardized Observability Protocols - Transmits observability data using universal formats like OTLP over HTTP or gRPC to ensure compatibility with diverse backend monitoring systems.
- Native Serialization Extensions - Offloads data encoding and transmission tasks to a native binary module to minimize performance overhead during high-volume telemetry export.
- Telemetry Plugin Interfaces - Uses standardized interfaces to allow developers to swap exporters, processors, and samplers without modifying the core telemetry collection logic.
- Observability Metrics Exporters - Exports application performance and usage metrics to external monitoring tools for detailed analysis.
