**全局配置** [Alertmanager](https://github.com/prometheus/alertmanager)通过命令行标志和配置文件进行配置。虽然命令行标志配置了不可变的系统参数，但配置文件定义了禁止规则，通知路由和通知接收器。 [可视化编辑器](https://prometheus.io/webtools/alerting/routing-tree-editor)可以帮助构建路由树。 如果想要查看所有命令，请使用命令`alertmanager -h`。 `Alertmanager`能够在运行时动态加载配置文件。如果新的配置有错误，则配置中的变化不会生效，同时错误日志被输出到终端。通过发送`SIGHUP`信号量给这个进程，或者通过HTTP POST请求`/-/reload`，Alertmanager配置动态加载到内存。 提供的[有效示例文件](https://github.com/prometheus/alertmanager/blob/master/doc/examples/simple.yml)显示上下文中的用法。 全局配置指定在所有其他配置上下文中有效的参数。它们还可用作其他配置节的默认值。 ``` global: # ResolveTimeout is the time after which an alert is declared resolved # if it has not been updated.
