Datadog has shit the bed for us multiple times in the last six months. Unannounced breaking API changes, unaddressed bugs, and now their embedded cert expired.

Our org is currently divided over further commitment to the service, or leaving them entirely. They've made it very hard to argue in their favor.

Their pricing doesn't scale well either, IMO. We have several hundred hosts running and for some of the smaller instance types it costs just as much to monitor than it does to run the entire machine.
