Prometheus 监控Redis

1.被监控端安装redis_exporter

tar xf redis_exporter-v1.20.0.linux-amd64.tar.gz
ln -s redis_exporter-v1.20.0.linux-amd64.tar.gz redis_exporter
[root@hz-prod redis_exporter]# cat /usr/lib/systemd/system/redis_exporter.service
[Unit]
Description=redis_exporter
Documentation=https://github.com/oliver006/redis_exporter
After=network.target
[Service]
Type=simple
ExecStart=/opt/redis_exporter/redis_exporter -redis.addr  127.0.0.1:6379 -redis.password zk123 
Restart=on-failure
[Install]
WantedBy=multi-user.target
systemctl start redis_exporter && systemctl enable redis_exporter
systemctl status redis_exporter
阿里云开放9121端口 由于普罗米修斯在天翼云 异地采集
[root@hz-prod redis_exporter]# netstat -lntup|grep 9121
tcp6       0      0 :::9121                 :::*                    LISTEN      15241/redis_exporte

2.普罗米修斯采集池中配置Redis采集地址

[root@Server-d0449e6d-d612-49ba-80cc-070b579955d6 prometheus-2.25.2.linux-amd64]# cat prometheus.yml 
  - job_name: Redis_exporter
    static_configs:
    - targets: [192.168.0.107:9121]
    - targets: ['114.55.165.145:9121']
[root@Server-d0449e6d-d612-49ba-80cc-070b579955d6 prometheus-2.25.2.linux-amd64]# systemctl restart prometheus

3.普罗米修斯targets查看redis exporter状态
