-------------------------------------------------------------------------------- 1 | # alertmanager-webhook 2 | 3 | ## 项目说明 4 | ``` 5 | 一个用于alertmanager转发告警信息到指定平台的webhook，适用于使用alertmanager作为告警工具的运维或者开发人员，也适用于自行开发告警平台的开发人员，告警信息转换成alertmanager的json告警格式即可。 6 | ``` 7 | 8 | ## 功能特性 9 | ``` 10 | 1. 支持自定义告警模板 11 | 2. 支持对接企业微信机器人 12 | 3. 支持对接飞书机器人 13 | 4. 支持对接钉钉机器人 14 | ``` 15 | 16 | 17 | ## 使用用法 18 | **项目依赖redis，需要先启动redis** 19 | 20 | **1. 二进制启动** 21 | 22 | 下载二进制文件，修改 alertmanager-webhook.yaml 23 | ```bash 24 | ./alertmanager-webhook -c alertmanager-webhook.yaml 25 | ``` 26 | **2. docker启动** 27 | ```bash 28 | docker run -d --name redis -v /root/redis.conf:/etc/redis/redis.conf -p 0.0.0.0:6379:6379 redis:5.0.0 redis-server /etc/redis/redis.conf 29 | docker run -d --name alertmanager-webhook -p 0.0.0.0:9095:9095 -v /root/alertmanager-webhook.yaml:/etc/alertmanager-webhook/alertmanager-webhook.yaml rainbowhhy/alertmanager-webhook:v1.0 30 | ``` 31 | **3. 模板修改** 32 | ```text 33 | 如果要修改告警模板，则需要编辑template/alert.tmpl，可以参照example中的模板来修改，docker启动则使用-v挂载，比如-v /root/dingding.tmpl:/data/alertmanager-webhook/template/alert.tmpl 34 | ``` 35 | 36 | ## 告警配置 37 | 38 | alertmanager中配置webhook 39 | 40 | ```yaml 41 | # alertmanager.yml 42 | ...... 43 | 44 | receivers: 45 | name: webhook 46 | webhook_configs: 47 | # 配置企业微信接口 48 | - url: 'http://127.0.0.1:9095/qywechat' 49 | # 配置飞书接口 50 | - url: 'http://127.0.0.1:9095/feishu' 51 | # 配置钉钉接口 52 | - url: 'http://127.0.0.1:9095/dingding' 53 | 54 | ...... 55 | ``` 56 | 57 | ## 使用示例 58 | **使用curl模仿alertmanager往webhook发送消息** 59 | 60 | ```bash 61 | curl -X POST -H "Content-Type: application/json" -d ' 62 | {"alerts": [ 63 | { 64 | "status": "firing|resolved", 65 | "labels": { 66 | "alertname": "机器宕机监测", 67 | "instance": "10.180.48.2", 68 | "job": "node_exporter", 69 | "serverity": "warning" 70 | }, 71 |

"2024-01-10T13:00:00Z", 77 | "fingerprint": "02f13394997e5211" 78 | } 79 | ] 80 | }' 127.0.0.1:9095/ 81 | 82 | # 注意firing|resolved选择一个，触发告警选择firing，告警恢复选择resolved； 从中选择一个，比如企业微信就是：127.0.0.1:9095/qywechat 83 | ``` 84 | 85 | ## 实现效果 86 | **企业微信告警效果** 87 | 88 | ![img](./example/image/qywechat.jpg) 89 | 90 | **飞书告警效果** 91 | 92 | ![img](./example/image/feishu.jpg) 93
