Same. At several companies I've been at we've used or investigated Datadog. One place accidentally spun up a bunch of EMR nodes on AWS for a single run (less than 1 hour), to which we got charged their going rate ($15/mo?) for every instance - even though they were only up for an hour. DD refused to reverse this, though eventually did help up make sure those nodes got excluded going forward ... gee thanks. $15/hr/node for monitoring is too rich for my blood.
Most recently it was looked at to help monitor a small Kubernetes test cluster. 3 nodes. Now the base rate of $18/mo is just fine... except now they charge $1/mo/container past 10 containers per host. Because K8s (depending on how you install it) runs a bunch of little containers handling various back end things, you might not deploy anything to the cluster and still be WAY over that 10 container limit. In our case it came out to like $200/mo to monitor 3 nodes - that were no where near fully loaded.
They've got a great product but their billing just has not ever really made sense. While I haven't used them, Wavefront makes a lot more sense - pay per metric. Got a bunch of containers that don't need monitoring, then don't send metrics (or send them infrequently). Easy.
