如何使用jenkins cli检查jenkins节点连接状态

我正在尝试检查特定的Jenkins节点是否使用 . 要获取节点详细信息，我可以使用

get node

命令，它将详细信息作为xml返回

<?xml version="1.0" encoding="UTF-8"?>
<slave>

但它不包括节点状态。任何人都知道如何通过Jenkins cli检查节点状态

因为我不知道使用的方法，我的建议是使用REST API：

http://jenkins.example.com/computer/:name/api/json

返回JSON数据，包括一个

脱机

字段

您可以通过以下URL获得所有代理（此处称为计算机）的概览：

我们可以使用管道来实现这一点。我确实为windows VDI机器使用了groovy脚本，下面是脚本

我从来不知道Jenkins有Json API。我也可以得到节点列表。非常感谢&这正是我想要的
