我正在使用以下命令在 kairosdb 中插入数据：reference

bin/kairosdb.sh 导入 -f 导出.txt

但在 kairosdb.log 文件中，我收到以下错误：

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，您描述的问题来自没有关联值的标签。T看起来你在前 10 行之后的值是 building_type 的空值（查找"building_type":""或类似）。

通过查看您的 JSON，我看到了几个不相关的可能问题：

  • 您的时间戳似乎以 Unix 秒为单位 - 它应该以毫秒为单位（由于 OpenTSDB 兼容性，它可以与 Telnet API 一起使用，但 KairosDB 需要毫秒）
  • 您的时间戳始终相同（因此您会一次又一次地更新相同的样本）
  • 您的值是一个字符串（虽然您可能希望使用长整数或浮点数），它可能有效，但我不建议以这种方式进行
