# Contributing Guidelines

Thank you for your interest in contributing to our project. Whether it's a bug report, new feature, correction, or additional
documentation, we greatly value feedback and contributions from our community.

Please read through this document before submitting any issues or pull requests to ensure we have all the necessary
information to effectively respond to your bug report or contribution.


## Reporting Bugs/Feature Requests

We welcome you to use the GitHub issue tracker to report bugs or suggest features.

When filing an issue, please check [existing open](https://github.com/aws/aws-xray-daemon/issues), or [recently closed](https://github.com/aws/aws-xray-daemon/issues?utf8=%E2%9C%93&q=is%3Aissue%20is%3Aclosed%20), issues to make sure somebody else hasn't already
reported the issue. Please try to include as much information as you can. Details like these are incredibly useful:

* A reproducible test case or series of steps
* The version of our code being used
* Any modifications you've made relevant to the bug
* Anything unusual about your environment or deployment


## Contributing via Pull Requests
Contributions via pull requests are much appreciated. Before sending us a pull request, please ensure that:

1. You are working against the latest source on the *master* branch.
2. You check existing open, and recently merged, pull requests to make sure someone else hasn't addressed the problem already.
3. You open an issue to discuss any significant work - we would hate for your time to be wasted.

To send us a pull request, please:

1. Fork the repository.
2. Modify the source; please focus on the specific change you are contributing. If you also reformat all the code, it will be hard for us to focus on your change.
3. Ensure local tests pass.
4. Commit to your fork using clear commit messages.
5. Send us a pull request, answering any default questions in the pull request interface.
6. Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.

GitHub provides additional document on [forking a repository](https://help.github.com/articles/fork-a-repo/) and
[creating a pull request](https://help.github.com/articles/creating-a-pull-request/).


## Finding contributions to work on
Looking at the existing issues is a great way to find something to contribute on. As our projects, by default, use the default GitHub issue labels ((enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any ['help wanted'](https://github.com/aws/aws-xray-daemon/labels/help%20wanted) issues is a great place to start.


## Code of Conduct
This project has adopted the [Amazon Open Source Code of Conduct](https://aws.github.io/code-of-conduct).
For more information see the [Code of Conduct FAQ](https://aws.github.io/code-of-conduct-faq) or contact
opensource-codeofconduct@amazon.com with any additional questions or comments.


## Security issue notifications
If you discover a potential security issue in this project we ask that you notify AWS/Amazon Security via our [vulnerability reporting page](http://aws.amazon.com/security/vulnerability-reporting/). Please do **not** create a public github issue.


## Licensing

See the [LICENSE](https://github.com/aws/aws-xray-daemon/blob/master/LICENSE) file for our project's licensing. We will ask you to confirm the licensing of your contribution.

We may ask you to sign a [Contributor License Agreement (CLA)](http://en.wikipedia.org/wiki/Contributor_License_Agreement) for larger changes.

# AWS X-Ray Daemon

The AWS X-Ray daemon is a software application that listens for traffic on UDP port 2000, gathers raw segment data, and relays it to the AWS X-Ray API.
The daemon works in conjunction with the AWS X-Ray SDKs and must be running so that data sent by the SDKs can reach the X-Ray service. For more information,
see [AWS X-Ray Daemon](https://docs.aws.amazon.com/xray/latest/devguide/xray-daemon.html).

## Getting Help

Use the following community resources for getting help with the AWS X-Ray Daemon. We use the GitHub issues for tracking bugs and feature requests.

* Ask a question in the [AWS X-Ray Forum](https://forums.aws.amazon.com/forum.jspa?forumID=241&start=0).
* Open a support ticket with [AWS Support](http://docs.aws.amazon.com/awssupport/latest/user/getting-started.html).
* If you think you may have found a bug, open an [issue](https://github.com/aws/aws-xray-daemon/issues/new).
* For contributing guidelines refer [CONTRIBUTING.md](https://github.com/aws/aws-xray-daemon/blob/master/CONTRIBUTING.md).

## Sending Segment Documents

The X-Ray SDK sends segment documents to the daemon to avoid making calls to AWS directly. You can send the segment/subsegment in JSON over UDP port 2000
to the X-Ray daemon, prepended by the daemon header : `{"format": "json", "version": 1}\n`

```
{"format": "json", "version": 1}\n{<serialized segment data>}
```
For more details refer : [Link](https://docs.aws.amazon.com/xray/latest/devguide/xray-api-sendingdata.html)

## Installing

The AWS X-Ray Daemon is compatible with Go 1.7 and later.

Install the daemon using the following command:

```
go get -u github.com/aws/aws-xray-daemon/...
```

You can also use [Glide](https://github.com/Masterminds/glide) to manage dependencies by using:

```
glide install
```
