Alertmanager与Prometheus的集成具体示例

Alertmanager 是 Prometheus 的一个重要组件，用于管理和处理来自 Prometheus 监控系统的警报。它提供了警报的抑制、分组、路由、静默等功能，帮助系统管理员有效地管理和响应警报。Alertmanager 通过与 Prometheus 集成来接收警报，基于配置规则处理警报并发送通知。

以下是 Alertmanager 与 Prometheus 集成的基本过程和步骤：

1. 配置 Prometheus 向 Alertmanager 发送警报

Prometheus 将监控数据与预设的告警规则进行对比，生成警报。为了将警报发送到 Alertmanager，需要在 Prometheus 配置文件 prometheus.yml 中设置 Alertmanager 的地址。

示例：配置 Prometheus 发送警报到 Alertmanager

# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
            - 192.168.188.101:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  - "/root/first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["localhost:9090"]
