我将我的cygnusagent配置为使用mySQL接收器，我使用了教程[1]中的notifcation脚本来测试它，但我的数据库中没有任何更改，也没有创建新的数据库。
我可能错过的任何想法？谢谢！

接收数据后，这是我的天鹅日志：

答案 0 :(得分：1)
您已评论配置文件的这一部分：
# GroupinInterceptor, do not change
#cygnusagent.sources.http-source.interceptors.gi.type = com.telefonica.iot.cygnus.interceptors.GroupingInterceptor$Builder
# Grouping rules for the GroupingInterceptor, put the right absolute path to the file if necessary
# See the doc/design/interceptors document for more details
#cygnusagent.sources.http-source.interceptors.gi.grouping_rules_conf_file = /usr/cygnus/conf/grouping_rules.conf
您必须取消注释这些参数，即使您不打算使用“分组规则”功能（只需留空/usr/cygnus/conf/grouping_rules.conf）。
