Alertmanager+邮箱警报安装配置

Posted 2020-12-21 wgx519

废话不多说，直接上步骤

 

1.下载 alertmanager-0.14.0.linux-amd64.tar.gz 到 、opt/minitor/alertmanager，不下载最新版是因为最新版（0.15.0）微信发送有推迟。

    

 

2.运行 tar -zxvf alertmanager-0.14.0.linux-amd64.tar.gz ,解压到当前目录。

  

3.执行 vim /opt/minitor/prometheus/prometheus.yml,添加一下配置文件（红色部分）：

# my global config
global:
  scrape_interval:     5s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 5s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).
 
# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
      - targets: [‘192.168.6.54:9093‘]
 
# Load rules once and periodically evaluate them according to the global ‘evaluation_interval‘.
rule_files:
  - "/opt/prometheus/prome/prometheus-2.0.0.linux-amd64/rules/first_rules.yml"

 

4.执行 vim /opt/minitor/prometheus/rules/first_rules.yml,添加一下内容：

groups:
- name: test-rules
   rules:
   - alert: InstanceDown # 告警名称
     expr: go_goroutines>10 # 告警的判定条件，参考Prometheus高级查询来设定
     for: 2m # 满足告警条件持续时间多久后，才会发送告警
     labels: #标签项
      team: node
     annotations: # 解析项，详细解释告警信息
      summary: "{{$labels.instance}}: has been down"
      description: "{{$labels.instance}}: job {{$labels.job}} has been down "
#      value: {{$value}}

 

5.执行 vim /opt/minitor/alertmanager/alert.yml，添加一下内容（具体参数含义参照上面的网址）：

# 全局配置项
global:
  resolve_timeout: 1m #处理超时时间，默认为5min
  smtp_smarthost: ‘smtp.163.com:25‘ # 邮箱smtp服务器代理
  smtp_from: ‘[e-mail]‘ # 发送邮箱名称
  smtp_auth_username: ‘[e-mail]‘ # 邮箱名称
  smtp_auth_password: ‘admin123‘ # 邮箱密码或授权码
#  wechat_api_url: ‘https://qyapi.weixin.qq.com/cgi-bin/‘ # 企业微信地址
 
 
# 定义模板信心
#templates:
#  - ‘/opt/prometheus/alertmanager/alertmanager-0.15.3.linux-amd64/test.tmpl‘
 
# 定义路由树信息
route:
  group_by: [‘alertname‘,‘cluster‘,‘service‘] # 报警分组依据
  group_wait: 10s # 最初即第一次等待多久时间发送一组警报的通知
  group_interval: 10s # 在发送新警报前的等待时间
  repeat_interval: 10m # 发送重复警报的周期 对于email配置中，此项不可以设置过低，否则将会由于邮件发送太多频繁，被smtp服务器拒绝
  receiver: ‘email‘ # 发送警报的接收者的名称，以下receivers name的名称
 
# 定义警报接收者信息
receivers:
  - name: ‘email‘ # 警报
    email_configs: # 邮箱配置
    - to: ‘[e-mail]‘  # 接收警报的email配置
      html: ‘{{ template "test.html" . }}‘ # 设定邮箱的内容模板
      headers: { Subject: "[WARN] 报警邮件"} # 接收邮件的标题
#    webhook_configs: # webhook配置
#    - url: ‘http://127.0.0.1:5001‘
#    - send_resolved: true
#      http_config: {}
#      url: http://flask-alert-service.monitoring:5000/send
#    wechat_configs: # 企业微信报警配置
#    - send_resolved: true
#      to_party: ‘1‘ # 接收组的id
#      agent_id: ‘1000002‘ # (企业微信-->自定应用-->AgentId)
#      corp_id: ‘******‘ # 企业信息(我的企业-->CorpId[在底部])
#      api_secret: ‘******‘ # 企业微信(企业微信-->自定应用-->Secret)
#      message: ‘{{ template "test_wechat.html" . }}‘ # 发送消息模板的设定
# 一个inhibition规则是在与另一组匹配器匹配的警报存在的条件下，使匹配一组匹配器的警报失效的规则。两个警报必须具有一组相同的标签。
#inhibit_rules:
#  - source_match:
#     severity: ‘critical‘
#    target_match:
#     severity: ‘warning‘
#    equal: [‘alertname‘, ‘dev‘, ‘instance‘]

 

6.执行 vim /opt/minitor/alertmanager/test.tmpl

{{ define "test.html" }}
<table border="1">
        <tr>
                <td>报警项</td>
                <td>实例</td>
                <td>报警阀值</td>
                <td>开始时间</td>
        </tr>
        {{ range $i, $alert := .Alerts }}
                <tr>
                        <td>{{ index $alert.Labels "alertname" }}</td>
                        <td>{{ index $alert.Labels "instance" }}</td>
                        <td>{{ index $alert.Annotations "value" }}</td>
                        <td>{{ $alert.StartsAt }}</td>
                </tr>
        {{ end }}
</table>
{{ end }} 

 

7.运行prometheus。

 

8.运行一下命令运行alertmanager.

nohup ./alertmanager --config.file=alert.yml --web.listen-address=:9093 &

 

9.可能出现的问题。

1.邮箱配置，请自行百度
2.服务器DNS配置。

可通过下面程序进行邮箱测试（由于篇幅问题，代码不进行展开）

public class WeChatData {
    //发送微信消息的URLString sendMsgUrl="https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=";
    /**
     * 成员账号
     */
    private String touser;
    /**
     * 消息类型
     */
    private String msgtype;
    /**
     * 企业应用的agentID
     */
    private int agentid;
    /**
     * 实际接收Map类型数据
     */
    private Object text;
    public Object getText() {
        return text;
    }
    public void setText(Object text) {
        this.text = text;
    }
    public String getMsgtype() {
        return msgtype;
    }
    public void setMsgtype(String msgtype) {
        this.msgtype = msgtype;
    }
    public int getAgentid() {
        return agentid;
    }
    public void setAgentid(int agentid) {
        this.agentid = agentid;
    }
    public String getTouser() {
        return touser;
    }
    public void setTouser(String touser) {
        this.touser = touser;
    }
}

public class WeChatUrlData {
    /**

    private String corpid;
    /**

    private String corpsecret;
    /**

    private String Get_Token_Url;
    /**

    private String SendMessage_Url;
    public String getCorpid() {
        return corpid;
    }
    public void setCorpid(String corpid) {
        this.corpid = corpid;
    }
    public String getCorpsecret() {
        return corpsecret;
    }
    public void setCorpsecret(String corpsecret) {
        this.corpsecret = corpsecret;
    }
    public void setGet_Token_Url(String corpid,String corpsecret) {
        this.Get_Token_Url ="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid="+corpid+"&corpsecret="+corpsecret;
    }
    public String getGet_Token_Url() {
        return Get_Token_Url;
    }
    public String getSendMessage_Url(){
        SendMessage_Url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=";
        return SendMessage_Url;
    }
}
