"""
|
|
This is a RESTful interface implemented using Flask micro framework.
|
|
The API is driven by configuration that is organized in terms of the monitoring classes
|
|
|
|
We designed the classes to be reusable (and powered by labels):
|
|
'monitoring-type':
|
|
'class':'<class-name>'
|
|
'config':<labeled-class-specific-configuration>'
