prometheus 对接飞书告警

prometheus对接飞书告警

• 环境

名称	ip地址	cpu	内存
yz-feishu	10.65.6.91	4c	8G

• 飞书创建群组机器人，参考飞书官网

• https://www.feishu.cn/hc/zh-CN/articles/360024984973

#备注：自定义机器人要增加ip 白名单限制
#还要复制 webhook 地址，后续要和 PrometheusAlert 中的路径进行拼接
https://open.feishu.cn/open-apis/bot/v2/hook/23b75d6axxxxxxxxxxxxxxxxxxxxx

• prometheus、alertmanager 部署

• https://www.cnblogs.com/lixinliang/p/14611521.html

• docker 启动安装 PrometheusAlert

docker  ps

• 配置模板

#访问
http://10.65.6.91:8080/

#添加并创建模板，模板内容

{{ $var := .externalURL}}{{ range $k,$v:=.alerts }}
{{if eq $v.status "resolved"}}

#复制创建模板的路径，并和飞书中创建机器人的url 进行拼接

• alertmanager 对接PrometheusAlert

#修改 alertmanager 中的 webhook_configs地址，将钉钉信息修改为 飞书, fsurl=https://open.feishu.cn/open-apis/bot/v2/hook/23b75d6axxxxxxxxxxxxxxxxxxxxx，这个地址为上面自定义机器人生成的 webhook 地址。
