## **alert_relabel_configs** 警报重新标记在发送到Alertmanager之前应用于警报。它具有与目标重新标记相同的配置格式和操作。外部标签后应用警报重新标记。 这样做的一个用途是确保具有不同外部标签的HA对Prometheus服务器发送相同的警报。 ## **alertmanager_config** 一`alertmanager_config`节指定Prometheus服务器向其发送警报的Alertmanager实例。它还提供参数以配置如何与这些Alertmanagers进行通信。 Alertmanagers可以通过`static_configs`参数静态配置，也可以使用其中一种支持的服务发现机制动态发现。 此外，`relabel_configs`允许从发现的实体中选择Alertmanagers，并对使用的API路径提供高级修改，这些修改通过`__alerts_path__`标签公开。 ``` # Per-target Alertmanager timeout when pushing alerts.
