+# Binary Logging
+
+## Format
+
+The log format is described in [this proto file](src/proto/grpc/binary_log/v1alpha/log.proto). It is intended that multiple parts of the call will be logged in separate files, and then correlated by analysis tools using the rpc\_id.
+
+## API
+
+The binary logger will be a separate library from gRPC, in each language that we support. The user will need to explicitly call into the library to generate logs. The library will provide the ability to log sending or receiving, as relevant, the following on both the client and the server:
+
+ - Initial metadata
+ - Messages
+ - Status with trailing metadata from the server
+ - Additional key/value pairs that are associated with a call but not sent over the wire
+
+The following is an example of what such an API could look like in C++:
+
+```c++
+// The context provides the method_name, deadline, peer, and metadata contents.
+// direction = CLIENT_SEND
+LogRequestHeaders(ClientContext context);
+// direction = SERVER_RECV
+LogRequestHeaders(ServerContext context);
+
+// The context provides the metadata contents
+// direction = CLIENT_RECV
+LogResponseHeaders(ClientContext context);
+// direction = SERVER_SEND
+LogResponseHeaders(ServerContext context);
+
+// The context provides the metadata contents
+// direction = CLIENT_RECV
+LogStatus(ClientContext context, grpc_status_code code, string details);
+// direction = SERVER_SEND
+LogStatus(ServerContext context, grpc_status_code code, string details);
+
+// The context provides the user data contents
+// direction = CLIENT_SEND
+LogUserData(ClientContext context);
+// direction = SERVER_SEND
+LogUserData(ServerContext context);
+
+// direction = CLIENT_SEND
+LogRequestMessage(ClientContext context, uint32_t length, T message);
+// direction = SERVER_RECV
+LogRequestMessage(ServerContext context, uint32_t length, T message);
+// direction = CLIENT_RECV
+LogResponseMessage(ClientContext context, uint32_t length, T message);
+// direction = SERVER_SEND
+LogResponseMessage(ServerContext context, uint32_t length, T message);
+```
+
+In all of those cases, the `rpc_id` is provided by the context, and each combination of method and context argument type implies a single direction, as noted in the comments.
+
+For the message log functions, the `length` argument indicates the length of the complete message, and the `message` argument may be only part of the complete message, stripped of sensitive material and/or shortened for efficiency.
+
+## Language differences
+
+In other languages, more or less data will need to be passed explicitly as separate arguments. In some languages, for example, the metadata will be separate from the context-like object and will need to be passed as a separate argument.

-gRPC Native Nuget package
-=========================
-
-Prerequisites
--------------
-
-NuGet binary
-
-Building the package
---------------------
-
-To build the native package, you need precompiled versions
-of grpc_csharp_ext library artifacts for Windows, Linux and Mac.
-In the normal gRPC release process, these are built by a Jenkins
-job and they are copied to the expected location before building
-the native nuget package is attempted.
-
-See tools/run_tests/build_artifacts.py for more details how
-precompiled artifacts are built.
-
-When building the native NuGet package, ignore the "Assembly outside lib folder"
-warnings (the DLLs are not assemblies, they are native libraries).
