每日shell脚本之自动配置Prometheus.yml并支持选择监控的节点数量、输入自定义IP和端口设置

bash 复制代码

#!/bin/bash

# 获取用户输入的节点数量
read -p "请输入要监控的节点数量： " node_count

# 生成Prometheus.yml配置文件
cat << EOF > Prometheus.yml
global:
  scrape_interval: 15s

scrape_configs:
EOF

for ((i=1; i<=$node_count; i++))
do
  read -p "请输入第 $i 个节点的IP地址： " node_ip
  read -p "请输入第 $i 个节点的端口号： " node_port
  cat << EOF >> Prometheus.yml
  - job_name: 'node$i'
    static_configs:
      - targets: ['$node_ip:$node_port']
EOF
done

cat << EOF >> Prometheus.yml
storage:
  local:
    path: /var/lib/prometheus

rule_files:
  - /etc/prometheus/alert.rules

remote_write:
  - url: http://remote-write-url:8080/api/v1/write
    write_relabel_configs:
      - source_labels: [__name__]
        regex: '(.*)'
        target_label: __name__
        replacement: 'new_metric_name'

# 启动Prometheus进程
./prometheus --config.file=Prometheus.yml &
