##Dependencies

<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
  <div data-id="server-density-alerts" data-view="ServerDensityAlerts" data-title="Server Density" ></div>
</li>

##Settings

You'll need to add the your username, password and server density account url to your environment. Use the following names: SERVER_DENSITY_USERNAME, SERVER_DENSITY_PASSWORD, SERVER_DENSITY_ACCOUNT

Hello, I can't see my alerts into the dashing widget ... I've added

puts username
puts password
puts account

and i see that they are ok. But nothing when i try to see what is written into data[].

Would you have an idea ?

Thank you
Guillaume
