We use Keen a lot on our engineering team. In our case we send them a lot of a events, but only query a few dozen times a month. However those queries are done in times when we need to quickly query data. Saved our ass a few times since started using it. They have libs on all of the languages we use. There is no excuse for a frontend dev or backend dev on any team to just log as much data as they can. That's the key...the barrier is low enough where there really is no excuse AND you don't have dev ops screaming at you sending too much data.

Most of our non technical people can't use the dashboard (I think this is from lack of effort rather than something wrong on Keen's side), but it is powerful and easy to use. Someone doesn't have to know SQL or Hadoop to get what they want.

Anyways YMMV but we have really liked using it.

EDIT: like others have posted want to also say that they have great customer service. Have had no issues but feel like they have made sure I could get in touch if I needed to
