I used Kapacitor 1.x and Chronograf 1.x for a couple years. I found TICKscript to be confusing, underdocumented, and a pain to manage. I thought Chronograf was OK. I switched to Grafana for both alerts and data visualization and everything is just better than what I had with Kapacitor and Grafana. Kapacitor seemed to use a lot more CPU power, but that may be because data is streamed to it instead of periodically queried. What is it about those two products that you like enough to keep using them or wanting them to be developed?
