what is OpenTracing
 OpenTracing is a set of APIs and instrumentation conventions that have been designed to provide a standardized method for developers to monitor and manage distributed tracing in their distributed systems and microservices-based architectures. Distributed tracing is a method used to profile and monitor the performance of distributed systems, which can be composed of many different services that communicate with each other over a network.

OpenTracing allows developers to add instrumentation to their code in a way that is compatible with any distributed tracing system that implements the OpenTracing standard. This means that developers can easily switch between different tracing systems, or use multiple systems in parallel, without having to modify their application code.

OpenTracing provides a number of benefits, including:

* Improved visibility into the performance and behavior of distributed systems
* Simplified instrumentation and monitoring of microservices
* Reduced vendor lock-in by providing a standardized interface for distributed tracing
* Increased portability of tracing code between different tracing systems

Overall, OpenTracing is an important tool for developers who are building and managing complex distributed systems, as it helps to simplify the process of monitoring and optimizing these systems.
OpenTracing is an open source project that provides a standard for distributed tracing in software systems. It enables developers to instrument their applications to record and analyze traces of the execution of their applications. OpenTracing is used to troubleshoot and debug applications, identify performance issues, and monitor system health. It also enables the collection of application-specific data points for distributed systems, such as network latency and request/response latency.
