自建redis监控方案

开始

• 下载并安装构建

$ git clone https://github.com/oliver006/redis_exporter.git
$ cd redis_exporter/
$ go build .

• 验证

$ ./redis_exporter --version
INFO[0000] Redis Metrics Exporter <<< filled in by build >>>    build date: <<< filled in by build >>>    sha1: <<< filled in by build >>>    Go: go1.13.8    GOOS: linux    GOARCH: amd64

• 增加启动脚本(内容自己调整)

# cat /etc/systemd/system/redis_exporter.service
[Unit]
Description=redis_exporter
After=network.target
[Service]
Type=simple
ExecStart=/www/monitor/redis_exporter/redis_exporter  -redis.addr 127.0.0.1:6379  -redis.password ****** -web.listen-address 0.0.0.0:9121
Restart=on-failure
[Install]
WantedBy=multi-user.target

• 启动

$ systemctl enable redis_exporter.service
$ systemctl start redis_exporter.service
$ systemctl status redis_exporter.service

• 测试

  $ curl localhost:9121/metrics
