Prometheus使用blackbox_exporter监控端口及网站状态（七）
标签：复制 release div com port nec inux hub 场景
一、blackbox_exporter应用场景
HTTP 测试： 定义 Request Header 信息、判断 Http status / Http Respones Header / Http Body 内容
TCP 测试： 业务组件端口状态监听、应用层协议定义与监听
ICMP 测试： 主机探活机制
POST 测试： 接口联通性
SSL证书过期时间
二、blackbox_exporter安装
# 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进行管理blackbox_exporter服务 # vim /usr/lib/systemd/system/blackbox_exporter.service [Unit] Description=blackbox_exporter After=network.target [Service] User=root Type=simple ExecStart=/usr/local/blackbox_exporter/blackbox_exporter --config.file=/usr/local/blackbox_exporter/blackbox.yml Restart=on-failure [Install] WantedBy=multi-user.target # systemctl daemon-reload # systemctl start blackbox_exporter.service # systemctl enable blackbox_exporter.service
三、配置prometheus采集数据
# cd /usr/local/prometheus # vim prometheus.yml # my global config global: scrape_interval: 15s evaluation_interval: 15s alerting: alertmanagers: - static_configs: - targets: rule_files: # - "first_rules.yml" # - "second_rules.yml" scrape_configs: - job_name: ‘prometheus‘ static_configs: - targets: [‘192.168.5.237:9090‘] - job_name: ‘node‘ file_sd_configs: - refresh_interval: 30s files: - "/usr/local/prometheus/sd_config/node*.yml" - job_name: ‘docker‘ static_configs: - targets: [‘192.168.5.85:8080‘] - job_name: ‘mysql‘ static_configs: - targets: [‘192.168.5.237:9104‘] labels: app: zabbix-server-mysql # 网站监控 - job_name: ‘http_status‘ metrics_path: /probe params: module: [http_2xx] static_configs: - targets: [‘http://www.lzfn.com‘, ‘wiki.lzfn.com‘] labels: instance: http_status group: web relabel_configs: - source_labels: [__address__] target_label: __param_target - target_label: __address__ replacement: 192.168.5.85:9115 # ping 检测 - job_name: ‘ping_status‘ metrics_path: /probe params: module: [icmp] static_configs: - targets: [‘192.168.5.85‘] labels: instance: ‘ping_status‘ group: ‘icmp‘ relabel_configs: - source_labels: [__address__] target_label: __param_target - target_label: __address__ replacement: 192.168.5.85:9115 # 端口监控 - job_name: ‘port_status‘ metrics_path: /probe params: module: [tcp_connect] static_configs: - targets: [‘192.168.5.85:80‘, ‘192.168.5.85:9000‘, ‘192.168.5.85:8080‘] labels: instance: ‘port_status‘ group: ‘port‘ relabel_configs: - source_labels: [__address__] target_label: __param_target - target_label: __address__ replacement: 192.168.5.85:9115 # 检查配置文件并重启服务 # ./promtool check config prometheus.yml Checking prometheus.yml SUCCESS: 0 rule files found # systemctl restart prometheus.service
四、配置Grafana展示数据
使用9965模板，需要安装饼状态图插件，安装后重启grafana
grafana-cli plugins install grafana-piechart-panel systemctl restart grafana-server.service
