请建议如何解决此错误。

推荐答案

通常，您描述的问题来自提供的没有关联值的标签。 TIt看起来像在您的building_type的空值为10的第一行后面有值（查找building_type：或类似的）。

usually the problem you describe comes from tags being provided with no associated value. TIt looks like you have values after the 10 first lines with empty value for building_type (look for "building_type":"" or similar).

通过查看你的JSON我看到几个不相关的可能的问题：

By looking at your JSON I see several unrelated possible problems :

• 你的时间戳似乎是在Unix秒 - 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）


• 您的时间戳总是相同的（因此您更新相同的样本， / li>
  
• 您的值是一个字符串（您可能想使用长或浮动），它可能会工作，但我不建议这样做
