Question

我使用以下命令在kairosdb中插入数据：reference

bin / kairosdb.sh import -f export.txt

但是在kairosdb.log文件中我收到以下错误：

08-10|13:54:33.443 [main] INFO  [Main.java:267] -      KairosDB service started

我的export.txt文件是：

administrator@administrator-IdeaCentre-Q190:~/Abharthan/kairosdb$ head -10 export.txt

请建议如何解决此错误。

通常您描述的问题来自提供没有关联值的标签。 TIt看起来像你的第一行10之后的值为building_type的空值（查找"building_type":""或类似）。

通过查看您的JSON，我发现了几个不相关的可能问题：

您的时间戳似乎是在Unix秒内 - 它应该以毫秒为单位（由于OpenTSDB兼容性，可以使用Telnet API，但KairosDB需要毫秒）
您的时间戳始终相同（因此您再次更新相同的样本）
你的值是一个字符串（虽然你可能喜欢使用long或float），它可能有用，但我不建议以这种方式进行

Kairosdb错误度量[0]（名称= abcd）.tag [xyz] .value可能不为空
