# Servers metrics

Requirements and manual setup.


Since version 1.6.0 RoRvsWild monitors server metrics:

- Load average
- CPU
- Memory
- Swap
- Disk space

##Requirements

For now, only Linux servers are supported.

##Configuration

Metrics are grouped by hostnames. Cloud providers give random hostnames which change on every deployment. You can manually define them:

```yaml
# config/rorvswild.yml
production:
  api_key: API_KEY
  server:
    name: <%= "Some code that return a relevant hostname" %>
```

Here is the equivalent if you prefer initialising RoRvsWild manually:

```ruby
# config/initializers/rorvswild.rb
RorVsWild.start(api_key: "API_KEY", server: {name: "host.name"})
```
