I am inserting data in kairosdb using the command: reference

bin/kairosdb.sh import -f export.txt

but in the kairosdb.log file I am getting following error:

My export.txt file is:

Please suggest how to fix this error.

通常、あなたが説明する問題は、関連する値が指定されていないタグに起因します。TIt は、最初の 10 行の後に、Building_type の値が空の値を持っているようです ("building_type":""または類似のものを探します)。

あなたのJSONを見ると、関連のない問題がいくつか見られます:

  • タイムスタンプは Unix 秒単位のようです - ミリ秒単位である必要があります (OpenTSDB との互換性のために Telnet API で動作する可能性がありますが、KairosDB はミリ秒を想定しています)
  • タイムスタンプは常に同じです (したがって、同じサンプルを何度も更新します)。
  • あなたの値は文字列です（おそらくロングまたはフロートを使用したいでしょうが）、それはうまくいくかもしれませんが、この方法で進めることはお勧めしません
