Support for 'events' and 'service checks' (DataDog statsd extension)

[visciang]

Do you think we can extend the library to include events and service-checks reporting?

If you think we can go in that direction I will open a PR.

This added the functionality for a different lib, so it can probably be referenced. I support this feature's existence =)

Just wanted to add my +1 to this feature request, I see it's difficult to just have an event overlay on DD using this library.
