As one of the maintainers of go-graphite stack, I'd really like to know more about what didn't work for Gramnarly. Based on values they've provided I can deduce that it was carbonapi + go-carbon, though I wonder if they've considered migrating to graphite-clickhouse. I understand that now it is too late, but maybe more details would help to fix same problem for other people.<p>P.S. It is also nice to see that feature that I've added long time ago just to have simpler dev setup for myself (vm-backend support) is actually used by people, even though it required few fixes :) (or to be precise - used at least at some point, it is not very clear if they've migrated to built-in one)
