一 blackbox exporter介紹
GitHub地址：https://github.com/prometheus/blackbox_exporter
blackbox_exporter是Prometheuse官方提供的一個exporter，可以通過HTTP、HTTPS、DNS、TCP和ICMP對被監控節點進行監控和資料採集
- HTTP/HTTPS：URL/API可用性檢測；
- TCP：埠監聽檢測；
- ICMP：主機存活檢測；
- DNS：域名解析；
二 部署blackbox_exporter
2.1 下載blackbox_exporter
下載地址：https://prometheus.io/download/#blackbox_exporter
root@node-02:~# wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.19.0/blackbox_exporter-0.19.0.linux-amd64.tar.gz
2.2 部署blackbox_exporter
root@node-02:~# tar xf blackbox_exporter-0.19.0.linux-amd64.tar.gz -C /usr/local/ root@node-02:~# ln -sv /usr/local/blackbox_exporter-0.19.0.linux-amd64/ /usr/local/blackbox_exporter '/usr/local/blackbox_exporter' -> '/usr/local/blackbox_exporter-0.19.0.linux-amd64/'
2.3 建立blckbox_expoter.service檔案
root@node-02:~# cat /lib/systemd/system/blackbox_exporter.service [Unit] Description=Prometheus blackbox_exporter After=network.target [Service] ExecStart=/usr/local/blackbox_exporter/blackbox_exporter --config.file=/usr/local/blackbox_exporter/blackbox.yml --web.listen-address=:9115 Restart=on-failure [Install] WantedBy=multi-user.target
2.4 設定開機啟動
點選檢視程式碼
root@node-02:~# systemctl enable blackbox_exporter
Created symlink /etc/systemd/system/multi-user.target.wants/blackbox_exporter.service → /lib/systemd/system/blackbox_exporter.service.
root@node-02:~# systemctl start blackbox_exporter
root@node-02:~# systemctl status blackbox_exporter
