假设在使用Zabbix 4.2时出现以下情况。我们有一个核心交换机，两个分布式交换机和20个访问交换机，其中分布式交换机连接到核心，每个分布式交换机连接10个访问交换机。我正在使用SNMP v2c和模板cisco开关（官方的一个）监视所有它们。现在出现了问题，因为我无法轻松地在zabbix中定义设备依赖性。轻松地说，我的意思是，如果分布式交换机出现故障，我想针对该设备而不是与其连接的所有访问交换机发出警报。我可以定义如下。更改每个设备的触发器，并使它们依赖于分布式交换机的相应触发器。但是，这太浪费时间了。我该怎么办？任何帮助表示赞赏。

您是对的，没有一种简单的方法来设置这种依赖关系。
前段时间我不得不处理相同的情况，我编写了一个python依赖设置器，它使用“依赖主机组<->主主机”逻辑。
您可以对其进行修改以适合您的需要（有关依赖性目标，请参见masterTargetTriggerDescription和slaveTargetTriggerDescription），它可以工作，但几乎没有错误检查：使用后果自负！

我更新了Simone Zabberoni提供的代码，并将其重写以与Python 3，PyZabbix和YAML一起使用。
