KAIROSDB Client Library

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's used by the client.

Integrate the source code into your Java project

The red part is the source code section.

We set up a class to test the operation

The result of the execution is:

The above is the result of kairosdb execution, is not easy to operate AH! Let me introduce you to this!
