> i am the only person working on ML at Netdata and i can confirm we don't gather any data for ML purposes, which is actually my biggest challenge right now :)

Yeah I would have to imagine that it would be an issue. This is just my personal opinion, but I think there should be a way to provide anonymized data for building models for anomaly detection. Maybe an opt-in feature, as it would benefit everybody using netdata, but this is just my own personal opinion.
