I think what is missing is a tool that suggest you how to set hardward parameters (RAM, CPU) and configurations settings (n. workers etc...) based on usage metrics and it tells you when you need to scale servers.

Great point. To start off we shall provide different hardware configs like micro, small, medium, large, xlarge with the scale that they can handle.

We soon plan to emit metrics from different components of SigNoz and setup autoscaling of different components. Druid has already put some thought in autoscaling. Checkout https://druid.apache.org/docs/latest/configuration/index.htm... and https://www.adaltas.com/en/2019/07/16/auto-scaling-druid-wit...

That's what monitors are for, at least in datadog that's how it would work. "Tell me when available workers drops below x"

Yeah, but it doesn’t tell how how to set up Postgres parameters or Rails server workers or optimal thread size based on usage metrics. There are tons of parameters to config

agree, as Ankit mentioned, there are lots more that can be done here
