Prometheus 監(jiān)控服務(wù)端口、網(wǎng)站狀態(tài)等（黑盒監(jiān)測）
1、blackbox_exporter介紹
blackbox_exporter是Prometheus 官方提供的 exporter 之一，可以提供 http、dns、tcp、icmp 的監(jiān)控?cái)?shù)據(jù)采集。
blackbox_exporter 應(yīng)用場景：
HTTP 測試：?定義 Request Header 信息，判斷 Http status / Http Respones Header / Http Body 內(nèi)容
TCP 測試：業(yè)務(wù)組件端口狀態(tài)監(jiān)聽，?應(yīng)用層協(xié)議定義與監(jiān)聽
ICMP 測試：主機(jī)探活機(jī)制
POST 測試：接口聯(lián)通性
SSL 證書過期時(shí)間
2、安裝blackbox_exporter
# wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.16.0/blackbox_exporter-0.16.0.linux-amd64.tar.gz
#?tar xf blackbox_exporter-0.16.0.linux-amd64.tar.gz -C /usr/local/
#?ln -s /usr/local/blackbox_exporter-0.16.0.linux-amd64/ /usr/local/blackbox_exporter
#?使用systemd管理blackbox_exporter服務(wù)
#?vim /usr/lib/systemd/system/blackbox_exporter.service

# systemctl restart prometheus4、Grafana可視化展示
需要安裝餅狀態(tài)圖插件，安裝后重啟grafana。
grafana-cli plugins install?grafana-piechart-panel
systemctl restart grafana-server.service此模板ID為9965，數(shù)據(jù)源選擇Prometheus：
