Census - a resource measurement and tracing system

This directory contains code for Census, which will ultimately provide the following features for any gRPC-using system:

A dapper-like tracing system, enabling tracing across a distributed infrastructure.
RPC statistics and measurements for key metrics, such as latency, bytes transferred, number of errors etc.
Resource measurement framework which can be used for measuring custom metrics. Through the use of tags, these can be broken down across the entire distributed stack.
Easy integration of the above with Google Cloud Trace and Google Cloud Monitoring.

Files in this directory

Note that files and functions in this directory can be split into two categories:

Files that define core census library functions. Functions etc. in these files are named census_*, and constitute the core census library functionality. At some time in the future, these will become a standalone library.
Files that define functions etc. that provide a convenient interface between grpc and the core census functionality. These files are all named grpc_*.{c,h}, and define function names beginning with grpc_census_*.
