* **port**: This is the `http` service port which enables other application to manage rules by `restful API`.
* **database**: rules are stored in a `sqlite` database, this is the path of the database file (if the file does not exist, the alert application creates it automatically).
* **tdengine**: connection string of `TDEngine` server, note the database name should be put in the `sql` field of a rule in most cases, thus it should NOT be included in the string.
* **tdengine**: connection string of `TDEngine` server (please refer the documentation of GO connector for the detailed format of this string), note the database name should be put in the `sql` field of a rule in most cases, thus it should NOT be included in the string.
* **log > level**: log level, could be `production` or `debug`.
* **log > path**: log output file path.
* **receivers > alertManager**: the alert application pushes alerts to `AlertManager` at this URL.

* **database**：报警监测程序将规则保存到了一个 `sqlite` 数据库中，这个参数用于指定数据库文件的路径（不需要提前创建这个文件，如果它不存在，程序会自动创建它）。
* **tdengine**：`TDEngine` 的连接字符串，一般来说，数据库名应该在报警规则的 `sql` 语句中指定，所以这个字符串中 **不** 应包含数据库名。
