    ### Node Exporter 設定

    1. 在 node 產生一個使用者, 用來執行服務:
    ```shell
    sudo useradd -s /bin/false node-exporter
    ```
    2. 下載 [node exporter](https://prometheus.io/download/#node_exporter)
    ```shell
    export NODE_EXPORTER_VERSION=1.9.0 && wget https://github.com/prometheus/node_exporter/releases/download/v$NODE_EXPORTER_VERSION/node_exporter-$NODE_EXPORTER_VERSION.linux-$(dpkg --print-architecture).tar.gz
    ```
    3. 解壓縮
    ```shell
    tar xvf node_exporter-$NODE_EXPORTER_VERSION.linux-$(dpkg --print-architecture).tar.gz -C /opt/node_exporter
    ```
    4. 新增一個 service 執行 node-exporter - `/etc/systemd/system/node_exporter.service`:
    ```txt
    [Unit]
    Description=Node Exporter
    Wants=network-online.target
    After=network-online.target
    [Service]
    User=node-exporter
    Type=simple
    ExecStart=/opt/node_exporter/node_exporter --collector.systemd
    [Install]
    WantedBy=multi-user.target
    ```
    5. 啟動服務:
    ```shell
    sudo systemctl daemon-reload
    sudo systemctl enable --now node_exporter
    sudo systemctl status node_exporter
    ```
    6. 測試:
    ```shell
    curl http://<PVE_HOST>:9100/metrics
    ```

    ### Prometheus 設定
    新增 config 抓 node exporter:
    ```
    scrape_configs:
    - job_name: node
    static_configs:
    - targets: ['localhost:9100']
    ```
    ### Grafana 設定
    匯入 dashboard - [Node Exporter Full](https://grafana.com/grafana/dashboards/1860-node-exporter-full/) ID: `1860`
