使用Prometheus监控bind9的DNS服务

*  首先编译bind\_exporter，编译方式参见[bind\_exporter][bind_exporter]
 *  创建一个systemd配置文件来运行bind\_exporter

vi /etc/systemd/system/bind_exporter.service

内容如下，注意此处的用户和组使用与named程序相同的用户和组“named”。--web.listen-address为对外暴露的metric地址和端口，Prometheus从此处抓取bind\_exporter的metrics；--bind.stats-url为本地bind服务绑定的地址和IP

[Unit]
    Description=bind_exporter
    Documentation=https://github.com/digitalocean/bind_exporter
    Wants=network-online.target
    After=network-online.target
    
    [Service]
    Type=simple
    User=named
    Group=named
    ExecReload=/bin/kill -HUP $MAINPID
    ExecStart=/opt/bind_exporter/bind_exporter \
      --bind.pid-file=/var/run/named/named.pid \
      --bind.timeout=20s \
      --web.listen-address=0.0.0.0:9119 \
      --web.telemetry-path=/metrics \
      --bind.stats-url=http://localhost:53/ \
      --bind.stats-groups=server,view,tasks
    
    SyslogIdentifier=bind_exporter
    Restart=always
    
    [Install]
    WantedBy=multi-user.target

*  加载并启动bind\_export

systemctl daemon-reload
    systemctl restart bind_exporter.service

*  在/etc/named.conf中添加如下内容，注意“statistics-channels”是与“options”并列的，而不是位于“options”内部

statistics-channels {
      inet 127.0.0.1 port 53 allow { 127.0.0.1; };
    };

重新启动named

service named restart

*  在Prometheus的yml文件中添加如下job，重新启动Prometheus即可

- job_name: dns-master
        static_configs:
          - targets: ['10.85.6.66:9119']
            labels:
              alias: dns-master

在Prometheus的targets中可以看到新加的内容

可以通过“curl http://10.85.6.66:9119/metrics”来获取bind\_exporter支持的metrics以及方法，最常用的方法为“bind\_up”，用于查看一个bind服务是否启动，值1表示启动成功![1334952-20190612231202076-2008401186.png][]
