# Deployments tracking

automatic and manual configuration


Since version 1.6.0, RorVsWild compares deployments.
Deployments tracking can help to find when a performance deterioration or a new error was introduced.

## Automatic configuration

It is working without any actions from your part if your app is:

- Deployed via **Capistrano**
- Inside a **Git repository**
- Hosted on Heroku with **Dyno metadata** enabled
- Hosted on **Scalingo**

## Manual configuration

Because we are not aware of all cloud hosting providers, there is a generic method to provide these data via the configuration:

```yaml
# config/rorvswild.yml
production:
  api_key: YOUR_API_KEY
  deployment:
    revision: <%= "Deployment version" %> # Mandatory
    description: <%= "Optional description such as a Git message" %>
    author: <%= "Deployment author's name" %>
    email: <%= "emailOf@theAuthor.com" %>
```

If you prefer initialising RorVsWild manually:

```yaml
# config/initializers/rorvswild.rb
RorVsWild.start(api_key: "YOUR_API_KEY", deployment: {
  revision: "Unique version number such as Git commit ID",
  description: "Message such as in Git",
  author: "Deployer's name",
  email: "Deployer's email"
})
```

Only the revision is mandatory, but it's better if you are able to provide more information.
