Microsoft Correlation Vector PHP
================================

[](#microsoft-correlation-vector-php)

Background
----------

[](#background)

**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.
