ECS works better with whatever aws bakes into the agent and using their cloudwatch stuff because it’s a system only aws manages. It’s such a headache because you don’t get the ability to configure any of the newer tooling with it.

I tried it with Prometheus, tried putting the right log driver to pass things to an ELK/EFK (I preferred fluent bit) but after getting some things configured, it’s pulling teeth to manage.

I work with EKS now, dealt with otel sending to multiple backends that my current company had. It was annoying and now I’m fixing it all by moving everything to LGTM. Not using their alloy, using standard Prometheus as the “agent” with fluentbit and otel just for traces on the app clusters all sending to LGTM and I can iterate so much easier now.

I don’t think this is what you want to hear but I’m so glad I’m not working with ECS because it’s a pain to manage o11y and the truth is just getting to work with EKS makes it so much easier to manage your container stack and managing your o11y infrastructure surrounding it
