Librato has been promoted as Appoptics now but no documentation to migrate from librato to appoptics

[jaswinder-saini]

I have a codebase that uses librato-sidekiq, librato-rescue i.e https://github.com/impactdialing/impactdialing
but new signup to librato dashboard has been removed with appoptics and appoptics just provide a agent key while I was using librato with username, key, source path. I haven't came across any documentation to move from librato to appoptics.
Let me know how we can use librato settings with appoptics
