We migrated from newrelic to datadog (for cost reasons LMAO) a while back and I miss NRQL every single day I'm building a dashboard.

I enjoy having everything instrumented and in one spot, it's super powerful, but I am currently advocating for self hosting loki so that we can have debug+ level logs across all environments for a much much lower cost. Datadog is really good at identifying anomalies, but the cost for logs is so high there's a non-trivial amount of savings in sampling and minimizing logging. I HATE that we have told devs "don't log so much" -- that misses the entire point of building out a haystack. And sampling logs at 1%, and only logging warnings+ in prod makes it even harder to identify anomalies in lower environments before a prod release.

last hot take: The UX in kibana in 2016 was better than anything else we have now for rapidly searching through a big haystack, and identifying and correlating issues in logs.
