I write and maintain an open source monitoring tool and I looked into adding a mode to output metrics in Netdata format and ran away screaming. It's just an unstructured text format where you output commands to stdout, one per line. Each command consists of whitespace-separated fields. Which field is the units? Oh, the 4th. And some fields are optional, I'm not even sure how that works but I think you can't skip an optional field if you then want to use any field after that. It's like structured data formats like JSON or god forbid XML never happened.
