kairosdb client库

The KairosDB client is a Java library that makes sending metrics and querying the KairosDB server simple. The HttpClient class is used to push metrics or query the KairosDB server. The library uses the builder pattern to simplify the task of creating the JSON that is used by the client.

将源码集成到你的java项目中

红色部分就是源码部分。

我们建立一个class来测试操作

public static void main(String[] args) throws URISyntaxException, IOException {

}

执行结果为：

以上就是kairosdb执行的结果，是不是操作起来比较简单啊！先介绍到这吧！
