Might be interesting to check out SigNoz (https://signoz.io)

Has all the three key signals like Metrics, Traces & logs in a single pane and it is much more cost effective compared to Datadog/NewRelic. And if you want, you can just host it your self as it is open source (https://github.com/signoz/signoz)
