prometheusblackbox_exporter _prometheus

恢弘志士之气，不宜妄自菲薄。这篇文章主要讲述prometheusblackbox_exporter相关的知识，希望能为你提供帮助。
一、概述1、 HTTP 测试

定义 Request Header 信息
判断 Http status / Http Respones Header / Http Body 内容

2、 TCP 测试

业务组件端口状态监听
应用层协议定义与监听

3、 ICMP 测试

主机探活机制

4、 POST 测试

接口联通性

5、 SSL 证书过期时间二、安装blackbox_exporter安装包
以linux系统为例，下载编译好的二进制包，解压使用：
1、下载并解压

# wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.19.0/blackbox_exporter-0.19.0.linux-amd64.tar.gz # tar -zxvf blackbox_exporter-0.19.0.linux-amd64.tar.gz # cd blackbox_exporter-0.19.0.linux-amd64/

2、验证是否安装成功

# ./blackbox_exporter --version blackbox_exporter, version 0.19.0 (branch: HEAD, revision: 5d575b88eb12c65720862e8ad2c5890ba33d1ed0) build user:root@2b0258d5a55a build date:20210510-12:56:44 go version:go1.16.4 platform:linux/amd64

3、启动blackbox_exporter

nohup ./blackbox_exporter &

4、验证是否启动成功

# netstat -utpln|grep blackbox (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp600 :::9115:::*LISTEN25185/./blackbox_ex

5、创建systemcd服务(centos7系统可以用)

$ vim /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

三、prometheus.yml中加入blackbox_exporter 1、监控主机存活状态

# vim prometheus.yml - job_name: crawler_status metrics_path: /probe params: module: [icmp] static_configs: - targets: [\'10.45.3.8\',\'10.45.3.9\',\'10.45.3.10\',\'10.45.3.11\'] labels: instance: node_status group: \'node\' relabel_configs: - source_labels: [__address__] target_label: __param_target - source_labels: [__param_target] target_label: instance - target_label: __address__ replacement: 127.0.0.1:9115

2、监控主机端口存活状态

- job_name: \'crawler_port_status\' metrics_path: /probe params: module: [tcp_connect] static_configs: - targets: [\'10.45.3.8:3128\'] labels: instance: \'port_status\' group: \'tcp\' relabel_configs: - source_labels: [__address__] target_label: __param_target - source_labels: [__param_target] target_label: instance - target_label: __address__ replacement: 127.0.0.1:9115

3、监控网站状态

- job_name: qianxin_web_status metrics_path: /probe params: module: [http_2xx] static_configs: - targets: [\'https://www.qianxin.com\'] labels: instance: qianxin_web_status group: \'web\' relabel_configs: - source_labels: [__address__] target_label: __param_target - target_label: __address__ replacement: 127.0.0.1:9115- job_name: baidu_web_status metrics_path: /probe params: module: [http_2xx] static_configs: - targets: [\'https://www.baidu.com\'] labels: instance: baidu_web_status group: \'web\' relabel_configs: - source_labels: [__address__] target_label: __param_target - target_label: __address__ replacement: 127.0.0.1:9115- job_name: jd_web_status metrics_path: /probe params: module: [http_2xx] static_configs: - targets: [\'https://www.jd.com\'] labels: instance: jd_web_status group: \'web\' relabel_configs: - source_labels: [__address__] target_label: __param_target - target_label: __address__ replacement: 127.0.0.1:9115

4、检查配置文件是否书写正确
