一、部署 prometheus 环境

1.1 下载安装包

prometheus、alertmanager、pushgateway、node_exporterhttps://prometheus.io/download/
prometheus-webhook-dingtalkhttps://github.com/timonwong/prometheus-webhook-dingtalk/tree/main
grafanahttps://grafana.com/grafana/download
jmx_exporterhttps://github.com/prometheus/jmx_exporter

1.2 解压安装

新建一个 /monitor 目录把上面下载的 tar.gz 包都解压安装在 /monitor 目录下并重命名如下名字

1.3 修改配置文件

1.3.1 hadoop-env.sh

修改完后要把这个文件 scp 给各个 Hadoop 节点

[root@hadoop01 ~]# cd /bigdata/hadoop/server/hadoop-3.2.4/etc/hadoop/

1.5 启动服务

把上述服务启动即可

注意prometheus-webhook-dingtalk 服务需要用下面方式启动

cd /monitor/prometheus-webhook-dingtalk/
nohup ./prometheus-webhook-dingtalk --web.listen-address="0.0.0.0:8060" --config.file="/monitor/prometheus-webhook-dingtalk/config.yml" &

二、补充

2.1 告警规则和 grafana 仪表盘文件下载

[root@hadoop01 ~]# cd /monitor/prometheus/
[root@hadoop01 /monitor/prometheus]# ls
console_libraries  consoles  data  LICENSE  NOTICE  prometheus  prometheus.yml  promtool  rule
[root@hadoop01 /monitor/prometheus]# ls rule/

2.5 内网环境

2.5.1 nginx公网

需要一台可以访问公网的 nginx 服务器来代理钉钉 api

[root@idc-master-02 ~]# cat /etc/nginx/conf.d/uat-prometheus-webhook-dingtalk.conf
server {
    listen 30080;

    location /robot/send {
        proxy_pass https://oapi.dingtalk.com;
        proxy_set_header Host oapi.dingtalk.com;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

2.5.2 config

[root@localhost-13 ~]# cat /opt/prometheus-webhook-dingtalk/config.yml 

targets:
  webhook1:
    url: http://10.0.4.11:30080/robot/send?access_token=0d6c5dc25fa3f79cf2f83c92705fe4594dcc5b3xxx

      text: '{{ template "ops.content" . }}'

2.5.3 /etc/hosts

[root@localhost-13 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
