# 1DS C/C++ SDK

1DS C/C++ SDK enables cross-platform telemetry collection from various
Microsoft products. It enables data / telemetry upload to 1DS Collector++.

# Overview

One Data Strategy (1DS) is a cross-org initiative with five teams across the
company coming together to unify multiple telemetry efforts at Microsoft. This
includes the teams that built Asimov, Aria, Shared Data Platform, Geneva, OMS,
Application Insights, and Visual Studio App Center. We aim to create a unified
data production, collection, and set of tools for key scenarios for the entire
company. Collector++ is the externally-facing destination end-point where
data/telemetry is uploaded to that subsequently routes the data to Microsoft
internal data pipeline.

```
We need a data culture where every engineer, every day, is looking at the
usage data, learning from that usage data, questioning what new things to
test out with our products, and being on that improvement cycle which is the
lifeblood of Microsoft...

# Getting Started

The SDK is released as a [source package](https://github.com/microsoft/cpp_client_telemetry/releases)
every month, following the [milestones](https://github.com/microsoft/cpp_client_telemetry/milestones).

  * **Supported** - these platforms are known to work well with the SDK in
    production.
  * **Covered by CI** - these platforms are tested as part of CI.
</details>

## Test

There are two sets of tests available:
* [tests/unittests](tests/unittests) - unit tests that verify operation of
  each individual component.
* [tests/functests](tests/functests) - functional tests that verify
  customer-facing APIs and features, they also cover the flow of data to
  Collector++.

These tests use Google Test / Google Mock framework and get built alongside
the SDK. Launch `functests` and `unittests` binary executables to capture
the test results.

# Getting Support

We recommend [GitHub issues](https://github.com/microsoft/cpp_client_telemetry/issues)
as the communication channel for both feature requests and issues.

We are also available on email and community meeting, please refer to [CONTRIBUTING.md](CONTRIBUTING.md)
for more details.

_**Note**: Please refer to the supported [platforms](#build),
anything not in the list should be treated as a feature request. The SDK is
released as source package, there is no plan to release prebuilt binaries.
Build issues are in general out of the support scope due to the unlimited
number of build flags combinations._
