golang实现的

POST http://192.168.1.107:9093/api/v1/alerts:  prometheus post 给 alertmanager的url地址

content-type:application/json

[{

  "labels":{

    "alertname":"InstanceDown",

    "instance":"192.168.1.108:9100",

    "job":"remote",

    "severity":"page"

  }

  "annotations":{

    "description":"192.168.1.108:9100 of job remote has been down for more than  5 minutes.",

    "summary":"Instance 192.168.1.108:9100 down"

  }

  "startsAt":"2019-06-07T18:22:24.456891295+08:00",

  "endsAt":"2019-06-07T18:24:09.456891295+08:00",

  "generatorURL":"http://192.168.1.109:9090/graph?g0.expr=up+%3D%3D+0&g0.tab=1"

}]

对应prometheus 实例配置如下：

  - job_name: 'remoge'

    static_configs:

    - targets: ['192.168.1.108:9100']

alert rules规则配置如下：

name:example

rules:

- alert:InstanceDown

  expr: up==1

  for:2m

  labels:

    severity: page

  annotations:

    summary: "Instance {{ $labels.instance }} down"

    description: "{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 5 minues."

ubuntu1604安装，使用

wget https://dl.grafana.com/oss/release/grafana_6.1.3_amd64.deb
sudo dpkg -i grafana_6.1.3_amd64.deb

#below from  https://www.cnblogs.com/xkus/p/7462953.html

systemctl daemon-reload

systemctl start grafana-server

systemctl status grafana-server

systemctl enable grafana-server.service

左侧configuration，data source，add data source，

设置一个name

http url输入http://localhost:9090，如果promethues是本机，其他默认

点选save&test

dashboards，import prometheus2.0和grafana metrics
