having a Netdata agent taking your machine's CPU to 99% shouldn't happen, not sure when was the list time you tried it but a lot of recent improvements have been done on the Netdata Agent

also, with Netdata you can achieve the same architecture design using a Netdata Parent that could be your "control node" and to where you stream the metrics of the nodes you want to keep running with as less load as possible - you can even offload the health engine and the machine learning

take a look at https://learn.netdata.cloud/docs/streaming/ and https://learn.netdata.cloud/docs/configuring/how-to-optimize...

Netdata doesn't have any paid service at the moment, event the Cloud service is free.

There are plans in the future for some paid plan but it won't remove features, it is more on having longer retention on metadata, role based access, support, etc.
