Prometheus Blackbox_exporter笔记

一、安装Promtheus

在 Prometheus 官网 Download | Prometheus 获取适用于 Linux 的 Prometheus 安
装包，这里我选择最新的 2.46.0 版本，我是 Linux 系统，选择下载 prometheus-2.46.0.linux-amd64.tar.gz
下载安装包：
wget https://github.com/prometheus/prometheus/releases/download/v2.46.0/prometheus-
2.46.0.linux-amd64.tar.gz解压安装包
tar zxvf prometheus-2.46.0.linux-amd64.tar.gz进到解压目录
cd prometheus-2.46.0.linux-amd64/查看版本信息
./prometheus --version
生成prometheus启动脚本，自行修改目录，我的解压目录是/opt/prometheus-2.46.0.linux-amd64/prometheus
vim /etc/systemd/system/prometheus.service
[Unit]
Description=Prometheus
Documentation=https://prometheus.io/docs/introduction/overview/
Wants=network-online.target
After=network-online.target[Service]
ExecStart=/opt/prometheus-2.46.0.linux-amd64/prometheus \--config.file=/opt/prometheus-2.46.0.linux-amd64/prometheus.yml \--storage.tsdb.path=/opt/prometheus-2.46.0.linux-amd64/data
ExecReload=/bin/kill -HUP $MAINPID
TimeoutStopSec=20s
Restart=always[Install]
WantedBy=default.target
systemctl daemon-reload
systemctl enable prometheus
systemctl start prometheus

systemctl status prometheus

访问http://IP:9090/targets进行确认

二、安装Blackbox_expoter

下载地址：Releases · prometheus/blackbox_exporter · GitHub

tar zxvf blackbox_exporter-0.24.0.linux-amd64.tar.gz -C /usr/local/

vim /etc/systemd/system/blackbox_exporter.service
[Unit]
Description=Blackbox Exporter
Wants=network-online.target
After=network-online.target[Service]
ExecStart=/usr/local/blackbox_exporter-0.24.0.linux-amd64/blackbox_exporter \--config.file=/usr/local/blackbox_exporter-0.24.0.linux-amd64/blackbox.yml
ExecReload=/bin/kill -HUP $MAINPID
TimeoutStopSec=20s
Restart=always[Install]
WantedBy=default.target
systemctl daemon-reload
systemctl enable blackbox_exporter
systemctl start blackbox_exporter

systemctl status blackbox_exporter

访问IP：9115进行确认

三、安装Grafana

下载地址：

Download Grafana | Grafana Labs

wget https://dl.grafana.com/oss/release/grafana-10.1.0-1.x86_64.rpm

yum install -y urw-fonts
rpm -ivh grafana-10.1.0-1.x86_64.rpm

数据配置路径，比如数据目录、日志目录、插件目录：/etc/sysconfig/grafana-server
默认的用户名和密码为 admin ，也可以在配置文件 /etc/grafana/grafana.ini中配置 admin_user 和 admin_password 两个参数来进行覆盖。
配置中文界面：
vim /etc/grafana/grafana.ini
default_language = zh-Hans
systemctl daemon-reload
systemctl enable grafana-server.service
systemctl start grafana-server

访问 http:IP:3000 进行确认

四、配置Prometheus

配置prmetheus.yml使用blackbox_exporter

vim /opt/prometheus-2.46.0.linux-amd64/prometheus.yml

检查网站状态，网络状态，与端口存活。

# my global config
global:scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.# scrape_timeout is set to the global default (10s).# Alertmanager configuration
alerting:alertmanagers:- static_configs:- targets:# - alertmanager:9093# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:# - "first_rules.yml"# - "second_rules.yml"# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.- job_name: "prometheus"# metrics_path defaults to '/metrics'# scheme defaults to 'http'.static_configs:- targets: ["localhost:9090"]- job_name: 网站状态metrics_path: /probeparams:module: [http_2xx]static_configs:- targets:- http://www.baidu.com- http://www.jd.comlabels:group: webrelabel_configs:- source_labels: [__address__]target_label: __param_target- source_labels: [__param_target]target_label: instance- target_label: __address__replacement: 192.168.31.80:9115- job_name: 网络联通性metrics_path: /probeparams:module: [icmp]static_configs:- targets:- 10.4.117.66- 10.4.117.69labels:group: icmprelabel_configs:- source_labels: [__address__]target_label: __param_target- source_labels: [__param_target]target_label: instance- target_label: __address__replacement: 192.168.31.80:9115- job_name: TCP端口状态metrics_path: /probeparams:module: [tcp_connect]static_configs:- targets:- 10.4.117.205:443- 10.4.117.205:38080labels:group: tcp-port-statusrelabel_configs:- source_labels: [__address__]target_label: __param_target- source_labels: [__param_target]target_label: instance- target_label: __address__replacement: 192.168.31.80:9115

五、Grafana插件安装

默认仪表盘部分插件没有，示例安装：grafana-piechart-panel
grafana-cli plugins install grafana-piechart-panel
指定插件路径

vim /etc/grafana/grafana.ini
[plugin.piechart]
path = /var/lib/grafana/plugins/grafana-piechart-panel
