您好！
我制作了一个小型物联网设备，使用ESP32和几个传感器监测特定外壳内的情况。我想通过将数据发布到ThingSpeak云来监控这些数据，然后用Telegraf将其写入InfluxDB，最后使用Grafana中的InfluxDB数据源将其可视化。
到目前为止，除了一个小的例外，我已经让一切完美无瑕。这就是：我的telegrap配置中的一个插件失败，错误为：
分析度量失败：无法将字段"temperature"转换为类型int:strconv。ParseInt:解析"；15.4〃：无效语法
插件是[inputs.http]]和[[inputs.http.json_v2]]，我对它们所做的是根据我的ThingSpeak API进行身份验证并解析字段的json输出。然后，在[[inputs.http.json_v2.field]]下的/etc/telegraf/telegraf.conf中，我添加了type = int，否则Telegraph会将我的度量写入InfluxDB中的Strings，而可视化它们的唯一方法是使用一个表或一个stat，因为其余的流量查询都会失败，并出现错误unsupported input type for mean aggregate: string。然而，当我在配置文件中更改为type = float时，我会得到一个不同的错误：
不可处理的实体：向数据库写入点失败：部分写入：字段类型冲突：输入字段"温度"；"关于测量"；sensorData"；是类型float，已作为类型字符串存在，丢弃=1
我怀疑我错误地配置了解析器插件，但经过数小时的调试，我无法找到解决方案。
一些可能有用的信息：Telegraf版本：Telegraf 1.24.2Influxdb版本：InfluxDB v2.4.0请参阅下面的telegraf.conf以及错误消息。
如有任何帮助，我们将不胜感激！(：

通过将type = float留在telegraf.conf中的[[inputs.http.json_v2.field]]下，并在Influx中使用新的API键创建NEW存储桶来修复此问题。
问题是，我之前在telegraf.conf中定义的bucketsensor已经在我的流入数据库中创建了字段温度，该字段温度的类型设置为last(又名：String(，不能用新类型mean(别名：float(覆盖。
一旦我删除了所有预先存在的bucket，一切都开始按预期工作。
