Promethues如何针对站点、SSL监控 _Promethues

需求：使用监控插件名称：bloackbox exporterbloackbox exporter 是prometheus社区提供的黑盒监控解决方案，运行用户通过HTTP、HTTPS、DNS、TCP以及ICMP的方式对网络进行探测(主动监测主机与服务状态) 。
一、下载安装包部署wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.16.0/blackbox_exporter-0.16.0.linux-amd64.tar.gztar zxvf blackbox_exporter-0.16.0.linux-amd64.tar.gzmkdir /usr/local/exportermv blackbox_exporter-0.16.0.linux-amd64 /usr/local/exporter/blackbox_exporter/usr/local/exporter/blackbox_exporter/blackbox_exporter--config.file=/usr/local/exporter/blackbox_exporter/blackbox.yml配置文件

制作system启动文件（可忽略）

[root@Prometheus exporter]#cd /usr/lib/systemd/system# 配置blackbox的开机自启文件[root@Prometheus system]# cat blackbox_exporter.service [Unit]Description=blackbox_exporterAfter=network.target [Service]User=prometheusGroup=prometheusWorkingDirectory=/usr/local/exporter/blackbox_exporterExecStart=/usr/local/exporter/blackbox_exporter/blackbox_exporter[Install]WantedBy=multi-user.target# 启动[root@node00 system]# systemctl restart blackbox_exporter# 查看状态[root@node00 system]# systemctl status blackbox_exporter# 开机自启[root@node00 system]# systemctl enable blackbox_exporter```

二、配置promethus采集数据，修改promethus-server配置文件，监控URL地址

方法一、修改promethus-server的配置文件,添加blackbox_http_2xx (url直接写在文件中)
/usr/local/prometheus/prometheus.yml

 - job_name: 'blackbox_http_2xx'scrape_interval: 45smetrics_path: /probeparams:module: [http_2xx]# Look for a HTTP 200 response.static_configs:- targets:- https://www.baidu.com/- 172.0.0.1:9090- https://www.qq.comrelabel_configs:- source_labels: [__address__]target_label: __param_target- source_labels: [__param_target]target_label: instance- target_label: __address__replacement: 114.67.116.119:9115

方法二、修改promethus-server的配置文件,添加blackbox_http_2xx (url单独写一个规则文件)
/usr/local/prometheus/prometheus.yml

- job_name: "blackbox_http_file_test"metrics_path: /probeparams:module: [http_2xx]# Look for a HTTP 200 response.file_sd_configs:- refresh_interval: 1mfiles:- "/usr/local/prometheus/conf/blackbox*.yml"relabel_configs:- source_labels: [__address__]target_label: __param_target- source_labels: [__param_target]target_label: instance- target_label: __address__replacement: 114.67.116.119:9115

URL规则文件

[root@node00 prometheus]# cat conf/blackbox-dis.yml - targets:- https://www.alibaba.com- https://www.tencent.com- https://www.baidu.com

重启动promethus服务
三、grafana展示blackbox采集数据

1、选择--》import-->通过导入9965 ，获取监控展示模板。
