The idea behind this project is to intercept some objects coming from Datadog and display custom recommendations to improve the quality of monitors, dashboards, etc. based on Company's policies and rules.

Use case examples:

• Display a warning when a set of tags is not set on a monitor
• Inject templated monitor message for people to follow
• Suggest options and features to use based on initial configuration
• Add links to internal documentation

The inject.js script is used to automatically inject the injected.js script in all pages.

The injected.js script is simply listening to xhr calls and can answer to them. In this example, if the url called matches some defined pattern, the response of the xhr call is then analyzed. The result of the analysis then insert a DOM object inside the html page.
