一/Alertmanager说明

prometheus组件负责产生告警，不处理告警。 AlertManager组件是用来处理告警

Alertmanager定义告警机制，通过，Email，wechat等发送警报

Alertmanager可以定义分组，抑制，沉默。

二/定义通知模板

[root@10-0-0-93 alertmanager]#vi alertmanager.yml
global:
  resolve_timeout: 5m
  smtp_from: "jiankong123@zw.cn"
  smtp_smarthost: 'smtp.mxhichina.com:465'
  smtp_auth_username: "jiankong123@zw.cn"
  smtp_auth_password: "Dasdfghjkl"
  smtp_require_tls: false

# 邮箱模板
templates:
  - '/etc/alertmanager/alertmanager-tmpl/*.tmpl'

# 路由分组
route:
  group_by: ['alertname']
  group_wait: 10s
  group_interval: 5m
  repeat_interval: 15m
  receiver: 'ops'

# 接收配置
receivers:
- name: 'ops'
# 邮箱配置
  email_configs:
  - to: '{{ template "email.to" . }}'
    html: '{{ template "email.to.html" . }}'
    send_resolved: true
  webhook_configs:
  - url: http://172.22.2.8:8060/dingtalk/ops/send
    send_resolved: true

## 抑制器配置
#例如当集群不可用时，多条一样告警同时告警，接收人只希望接收到一条告警
inhibit_rules:
# 源标签警报触发时抑制含有目标标签的警报，在当前警报匹配 severity: 'critical'
  - source_match: 
      severity: 'critical'
    target_match:
      severity: 'warning'

三/设置邮件告警模板

[root@10-0-0-193 alertmanager-tmpl]# cat email.tmpl 
{{ define "email.from" }}jiankong123@wf.cn{{ end }}
{{ define "email.to" }}wf123@wf.cn{{ end }}
{{ define "email.to.html" }}
{{- if gt (len .Alerts.Firing) 0 -}}{{ range .Alerts }}
========================<br>
<h2>监控告警通知</h2>
告警地址: 测试环境监控 <br>
告警级别: {{ .Labels.severity }} <br>
告警类型: {{ .Labels.alertname }} <br>
故障主机: {{ .Labels.instance }} <br>
告警主题: {{ .Annotations.summary }} <br>
告警详情: {{ .Annotations.description }} <br>
触发时间: {{ .StartsAt.Format "2008-01-02 15:04:05" }} <br>
========================<br>
{{ end }}{{ end -}}
{{- if gt (len .Alerts.Resolved) 0 -}}{{ range .Alerts }}
========================<br>
<h2>监控告警恢复</h2>
告警地址: 测试环境监控 <br>
告警类型: {{ .Labels.alertname }} <br>
故障主机: {{ .Labels.instance }} <br>
告警主题: {{ .Annotations.summary }} <br>
告警详情: {{ .Annotations.description }} <br>
告警时间: {{ .StartsAt.Format "2008-01-02 15:04:05" }} <br>
恢复时间: {{ .EndsAt.Local.Format "2008-01-02 15:04:05" }} <br>
========================<br>
{{ end }}{{ end -}}
{{- end }}

四/设置钉钉告警

prometheus-webhook-dingtalk来进行钉钉告警

[root@10-0-0-193 webhook]# cat dingding.tmpl 
{{ define "__subject" }}
[{{ .Status | toUpper }}{{ if eq .Status "firing" }}:{{ .Alerts.Firing | len }}{{ end }}]
{{ end }}
 
{{ define "__alert_list" }}{{ range . }}
---
{{ if .Labels.owner }}@{{ .Labels.owner }}{{ end }}
**告警类型**: {{ .Labels.alertname }} 
**告警级别**: {{ .Labels.severity }} 
**告警主机**: {{ .Labels.instance }} 
**告警主题**: {{ index .Annotations "summary" }} 
**告警信息**: {{ index .Annotations "description" }}
**告警时间**: {{ dateInZone "2008.01.02 15:04:05" (.StartsAt) "Asia/Shanghai" }}
{{ end }}{{ end }}
 
{{ define "__resolved_list" }}{{ range . }}
---
{{ if .Labels.owner }}@{{ .Labels.owner }}{{ end }}
**告警类型**: {{ .Labels.alertname }} 
**告警级别**: {{ .Labels.severity }}
**告警主机**: {{ .Labels.instance }}
**告警主题**: {{ index .Annotations "summary" }} 
**告警信息**: {{ index .Annotations "description" }}
**告警时间**: {{ dateInZone "2008.01.02 15:04:05" (.StartsAt) "Asia/Shanghai" }}
**恢复时间**: {{ dateInZone "2008.01.02 15:04:05" (.EndsAt) "Asia/Shanghai" }}
{{ end }}{{ end }}
 
 
{{ define "default.title" }}
{{ template "__subject" . }}
{{ end }}
 
{{ define "default.content" }}
{{ if gt (len .Alerts.Firing) 0 }}
**====监控告警侦测到{{ .Alerts.Firing | len  }}个故障====**
{{ template "__alert_list" .Alerts.Firing }}
---
{{ end }}
 
{{ if gt (len .Alerts.Resolved) 0 }}
**====监控告警恢复{{ .Alerts.Resolved | len  }}个故障====**
{{ template "__resolved_list" .Alerts.Resolved }}
{{ end }}
{{ end }}
 
{{ define "ding.link.title" }}{{ template "default.title" . }}{{ end }}
{{ define "ding.link.content" }}{{ template "default.content" . }}{{ end }}
{{ template "default.title" . }}
{{ template "default.content" . }}
