配置Alertmanager发送报警到钉钉

配置Alertmanager发送报警到钉钉

一、配置步骤

1.1、创建钉钉机器人

打开电脑版钉钉，创建一个群，创建自定义机器人，按如下步骤创建：https://developers.dingtalk.com/document/app/custom-robot-access

群设置-->智能群助手-->添加机器人-->自定义-->添加

webhook：https://oapi.dingtalk.com/robot/send?access_token=7e7368e227cf8ac68f37c8690d7f8a13db5bbd1fcb109470ace31501b9051ee6

1.2、安装钉钉的webhook插件

# 在k8s的控制节点k8s-master1操作
tar zxvf prometheus-webhook-dingtalk-0.3.0.linux-amd64.tar.gz

# 启动钉钉报警插件
cd prometheus-webhook-dingtalk-0.3.0.linux-amd64
nohup ./prometheus-webhook-dingtalk --web.listen-address="0.0.0.0:8060" --ding.profile="cluster1=https://oapi.dingtalk.com/robot/send?access_token=7e7368e227cf8ac68f37c8690d7f8a13db5bbd1fcb109470ace31501b9051ee6" &

[root@k8s-master1 ~]# ss -lntp|grep 8060
LISTEN     0      128         :::8060                    :::*                   users:(("prometheus-webh",pid=78242,fd=3))

1.3、创建alertmanager-cm.yaml文件

# 对原来的文件备份
[root@k8s-master1 prometheus]# cp alertmanager-cm.yaml alertmanager-cm.yaml.bak
[root@k8s-master1 prometheus]# cat alertmanager-cm.yaml
kind: ConfigMap
apiVersion: v1
metadata:
  name: alertmanager
  namespace: monitor-sa
data:
  alertmanager.yml: |-
    global:
      resolve_timeout: 1m
      smtp_smarthost: 'smtp.163.com:25'
      smtp_from: '18665870472@163.com'
      smtp_auth_username: '18665870472'
      smtp_auth_password: 'GGCTEDQDVLKPCIID'
      smtp_require_tls: false
    route:
      group_by: [alertname]
      group_wait: 10s
      group_interval: 10s
      repeat_interval: 10m
      receiver: cluster1
    receivers:
    - name: cluster1
      webhook_configs:
      - url: 'http://192.168.40.180:8060/dingtalk/cluster1/send'
        send_resolved: true
