### 30 为什么开源版 TDengine 的主进程会建立一个与公网的连接？
|
||||
这个连接只会上报不涉及任何用户数据的最基本信息，用于官方了解产品在世界范围内的分布情况，进而优化产品，提升用户体验，具体采集项目为：集群名、操作系统版本、cpu信息等。
|
||||
|
||||
该特性为可选配置项，在开源版中默认开启，具体参数为 telemetryReporting , 在官方文档中有做说明，链接如下：[参数简介](https://docs.taosdata.com/reference/components/taosd/#%E7%9B%91%E6%8E%A7%E7%9B%B8%E5%85%B3)
|
||||
|
||||
您可以随时关闭该参数，只需要在taos.cfg 中修改telemetryReporting为 0，然后重启数据库服务即可。
|
||||
|
||||
代码位于:[点击此处](https://github.com/taosdata/TDengine/blob/62e609c558deb764a37d1a01ba84bc35115a85a4/source/dnode/mnode/impl/src/mndTelem.c)
|
||||
|
||||
此外，对于安全性要求极高的企业版 TDengine Enterprise 来说，此参数不会工作。
