Correlation Vector (a.k.a. cV) is a format and protocol standard for tracing and correlation of events through a distributed system based on a light weight vector clock. The standard is widely used internally at Microsoft for first party applications and services and supported across multiple logging libraries and platforms (Services, Clients - Native, Managed, JS, iOS, Android etc). The standard powers a variety of different data processing needs ranging from distributed tracing & debugging to system and business intelligence, in various business organizations.
- Make the standard specification externally available for implementation by non-Microsoft components or Open Source Microsoft components
- Support wire interop scenarios between Microsoft-internal and external tracing systems
- Describe the benefits of vector based tracing formats and to provide an exemplar vector based format for future standardization efforts with similar protocols
- Design Constraints and Scenarios for the Correlation Vector: Link
- Protocol Specification:
- Cpp (C++)
- CSharp (C#)
- Go
- Java
- JavaScript
