文章目录

    • 一、创建企业微信机器人
    • 二、配置AlterManager告警发送至企业微信
    • 三、Prometheus接入AlterManager配置
    • 四、部署Prometheus+AlterManager(放到一个Pod中)
    • 五、测试告警

注意：请基于 Prometheus+Grafana监控K8S集群(基于K8S环境部署)文章之上做本次实验。

一、创建企业微信机器人

1、创建企业微信机器人

点击登入企业微信网页版:

应用管理 > 机器人 > 创建应用

外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传

创建好之后如上图，我们获取 点击查看获取 Secret 值。

2、获取企业ID

在这里插入图片描述

二、配置AlterManager告警发送至企业微信

1、创建AlterManager ConfigMap资源清单

vim alertmanager-cm.yaml
---
kind: ConfigMap
apiVersion: v1
metadata:name: alertmanagernamespace: prometheus
data:alertmanager.yml: |-templates:- '/alertmanager/template/WeChat.tmpl'global:resolve_timeout: 1msmtp_smarthost: 'smtp.163.com:25'smtp_from: '18145536045@163.com'smtp_auth_username: '18145536045@163.com'smtp_auth_password: 'KCGZFUDCCKMNZMKB'smtp_require_tls: falseroute:group_by: [alertname]group_wait: 10sgroup_interval: 10srepeat_interval: 10mreceiver: wechat-001receivers:- name: 'wechat-001'wechat_configs:- corp_id: wwfb8d55841e190c10 # 企业IDto_user: '@all'             # 发送所有人agent_id: 1000002           # agentIDapi_secret: wa6kWECFthSpvdhcF-RPgjrIBzUvm-SpqXXXXXXXXXX # secret

执行YAML资源清单：

kubectl apply -f alertmanager-cm.yaml

三、Prometheus接入AlterManager配置

1、创建新的Prometheus ConfigMap资源清单，添加监控K8S集群告警规则

vim prometheus-alertmanager-cfg.yaml
---
kind: ConfigMap
apiVersion: v1
metadata:labels:app: prometheusname: prometheus-confignamespace: prometheus

执行资源清单：

kubectl apply -f prometheus-alertmanager-cfg.yaml

2、由于在prometheus中新增了etcd，所以生成一个etcd-certs，这个在部署prometheus需要

kubectl -n prometheus create secret generic etcd-certs --from-file=/etc/kubernetes/pki/etcd/server.key  --from-file=/etc/kubernetes/pki/etcd/server.crt --from-file=/etc/kubernetes/pki/etcd/ca.crt

四、部署Prometheus+AlterManager(放到一个Pod中)

1、在node-1节点创建/data/alertmanager目录，存放alertmanager数据

mkdir /data/alertmanager/template -p
chmod -R 777 /data/alertmanager

2、在node-1节点创建WeChat报警模板

vim /data/alertmanager/template/WeChat.tmpl{{ define "wechat.default.message" }}
{{- if gt (len .Alerts.Firing) 0 -}}
{{- range $index, $alert := .Alerts -}}
{{- if eq $index 0 }}
=========xxx环境监控报警 =========
告警状态：{{   .Status }}
告警级别：{{ .Labels.severity }}
告警类型：{{ $alert.Labels.alertname }}
故障主机: {{ $alert.Labels.instance }} {{ $alert.Labels.pod }}
告警主题: {{ $alert.Annotations.summary }}
告警详情: {{ $alert.Annotations.message }}{{ $alert.Annotations.description}};
触发阀值：{{ .Annotations.value }}
故障时间: {{ ($alert.StartsAt.Add 28800e9).Format "2006-01-02 15:04:05" }}
========= = end =  =========
{{- end }}
{{- end }}
{{- end }}
{{- if gt (len .Alerts.Resolved) 0 -}}
{{- range $index, $alert := .Alerts -}}
{{- if eq $index 0 }}
=========xxx环境异常恢复 =========
告警类型：{{ .Labels.alertname }}
告警状态：{{   .Status }}
告警主题: {{ $alert.Annotations.summary }}
告警详情: {{ $alert.Annotations.message }}{{ $alert.Annotations.description}};
故障时间: {{ ($alert.StartsAt.Add 28800e9).Format "2006-01-02 15:04:05" }}
恢复时间: {{ ($alert.EndsAt.Add 28800e9).Format "2006-01-02 15:04:05" }}
{{- if gt (len $alert.Labels.instance) 0 }}
实例信息: {{ $alert.Labels.instance }}
{{- end }}
========= = end =  =========
{{- end }}
{{- end }}
{{- end }}
{{- end }}

3、删除旧的prometheus deployment资源

kubectl delete deploy prometheus-server -n prometheus

4、创建deployment资源

vim prometheus-alertmanager-deploy.yaml
---
apiVersion: apps/v1
kind: Deployment
metadata:name: prometheus-servernamespace: prometheuslabels:app: prometheus
spec:replicas: 1selector:matchLabels:app: prometheuscomponent: server#matchExpressions:#- {key: app, operator: In, values: [prometheus]}#- {key: component, operator: In, values: [server]}template:metadata:labels:app: prometheuscomponent: serverannotations:prometheus.io/scrape: 'false'spec:nodeName: node-1 # 调度到node-1节点serviceAccountName: prometheus # 指定sa服务账号containers:- name: prometheusimage: prom/prometheus:v2.33.5imagePullPolicy: IfNotPresentcommand:- "/bin/prometheus"args:- "--config.file=/etc/prometheus/prometheus.yml"- "--storage.tsdb.path=/prometheus"- "--storage.tsdb.retention=24h"- "--web.enable-lifecycle"ports:- containerPort: 9090protocol: TCPvolumeMounts:- mountPath: /etc/prometheusname: prometheus-config- mountPath: /prometheus/name: prometheus-storage-volume- name: k8s-certsmountPath: /var/run/secrets/kubernetes.io/k8s-certs/etcd/- name: alertmanager#image: prom/alertmanager:v0.14.0image: prom/alertmanager:v0.23.0imagePullPolicy: IfNotPresentargs:- "--config.file=/etc/alertmanager/alertmanager.yml"- "--log.level=debug"ports:- containerPort: 9093protocol: TCPname: alertmanagervolumeMounts:- name: alertmanager-configmountPath: /etc/alertmanager- name: alertmanager-storagemountPath: /alertmanager- name: localtimemountPath: /etc/localtimevolumes:- name: prometheus-configconfigMap:name: prometheus-config- name: prometheus-storage-volumehostPath:path: /datatype: Directory- name: k8s-certssecret:secretName: etcd-certs- name: alertmanager-configconfigMap:name: alertmanager- name: alertmanager-storagehostPath:path: /data/alertmanagertype: DirectoryOrCreate- name: localtimehostPath:path: /usr/share/zoneinfo/Asia/Shanghai

执行YAML资源清单：

kubectl apply -f prometheus-alertmanager-deploy.yaml

查看状态：

kubectl get pods -n prometheus

在这里插入图片描述

5、创建AlterManager SVC资源

vim alertmanager-svc.yaml 
---
apiVersion: v1
kind: Service
metadata:labels:name: prometheuskubernetes.io/cluster-service: 'true'name: alertmanagernamespace: prometheus
spec:ports:- name: alertmanagernodePort: 30066port: 9093protocol: TCPtargetPort: 9093selector:app: prometheussessionAffinity: Nonetype: NodePort

执行YAML资源清单：

kubectl apply -f alertmanager-svc.yaml

查看状态：

kubectl get svc -n prometheus

在这里插入图片描述

五、测试告警

浏览器访问：http://IP:30066
在这里插入图片描述
如上图可以看到，Prometheus的告警信息已经发到AlterManager了，AlertManager收到报警数据后，会将警报信息进行分组，然后根据AlertManager配置的 group_wait 时间先进行等待。等wait时间过后再发送报警信息至企业微信！

在这里插入图片描述

如上图，告警信息已经成功发往企业微信了！！！
