Hi, > <1h: no sampling 1h~1d : intervals = 1m 1d~30d:intervals = 1h >30d：intervals = 1d
Looks ok to me. > Maybe adding a parameter in config to let users decide whether to enable down sampling is better. Of course. If there is no such a switch, some users may think the data is error. Besides, we can also add a parameter to let users define which aggregation function to use to downsampling the data, e.g., agv, max, min, random, first, last, etc.. Any suggestion? @Julian Feinauer <[email protected]> Best, ----------------------------------- Xiangdong Huang School of Software, Tsinghua University 黄向东 清华大学 软件学院 Jialin Qiao <[email protected]> 于2020年4月17日周五 下午8:55写道： > Hi, > > This is a good improvement to our grafana connector :) > > Maybe adding a parameter in config to let users decide whether to enable > down sampling is better.
