如何编写一个VPS Ping脚本来监控网络连接质量？

VPS Ping脚本如何编写？从零开始制作网络监控工具

#!/bin/bash
VPS Ping监控脚本
TARGET="8.8.8.8"  # 监控目标
COUNT=4           # Ping次数
INTERVAL=60       # 检测间隔(秒)
while true; do
    echo "$(date): 开始Ping测试..."
    ping -c $COUNT $TARGET
    echo "----------------------------------------"
    sleep $INTERVAL
done

#!/usr/bin/env python3
import subprocess
import datetime
import time
import sys
def pinghost(host, count=4):
    """执行Ping测试"""
    try:
        result = subprocess.run(
            ['ping', '-c', str(count), host],
            captureoutput=True,
            text=True,
            timeout=30
        )
        return result.returncode == 0, result.stdout
    except subprocess.TimeoutExpired:
        return False, "Ping超时"
def main():
    target = "8.8.8.8"
    logfile = "pingmonitor.log"
    
    print(f"开始监控 {target}...")
    
    while True:
        timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
        success, output = pinghost(target)
        
        status = "成功" if success else "失败"
        logentry = f"{timestamp} - Ping {target}: {status}\n"
        
        # 写入日志文件
        with open(logfile, "a") as f:
            f.write(logentry)
            if not success:
                f.write(f"详细信息: {output}\n")
        
        print(logentry.strip())
        time.sleep(60)
if name == "main":
    main()

步骤三：PowerShell脚本实现

• 执行环境：PowerShell 5.0+
• 依赖：Test-Connection命令

# VPS Ping监控脚本 - PowerShell版本
param(
    [string]$Target = "8.8.8.8",
    [int]$Count = 4,
    [int]$Interval = 60
)
$LogPath = "C:\logs\pingmonitor.log"
创建日志目录
$LogDir = Split-Path $LogPath -Parent
if (!(Test-Path $LogDir)) {
    New-Item -ItemType Directory -Path $LogDir -Force
}
Write-Host "开始监控目标: $Target"
while ($true) {
    $Timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
    
    try {
        $PingResult = Test-Connection -ComputerName $Target -Count $Count -Quiet
        $Status = if ($PingResult) { "成功" } else { "失败" }
        
        $LogEntry = "$Timestamp - Ping $Target`: $Status"
        Add-Content -Path $LogPath -Value $LogEntry
        
        Write-Host $LogEntry
    }
    catch {
        $ErrorEntry = "$Timestamp - 错误: $($.Exception.Message)"
        Add-Content -Path $LogPath -Value $ErrorEntry
        Write-Host $ErrorEntry -ForegroundColor Red
    }
    
    Start-Sleep -Seconds $Interval
}

步骤四：高级功能扩展

• 邮件库：smtplib (Python)
• 图表库：matplotlib (可选)

#!/usr/bin/env python3
import subprocess
import datetime
import time
import smtplib
from email.mime.text import MIMEText
class AdvancedPingMonitor:
    def init(self, target, emailconfig=None):
        self.target = target
        self.emailconfig = emailconfig
        self.failcount = 0
        
    def sendalert(self, message):
        """发送邮件告警"""
        if not self.emailconfig:
            return
            
        try:
            msg = MIMEText(message)
            msg['Subject'] = f'VPS Ping告警 - {self.target}'
            msg['From'] = self.emailconfig['from']
            msg['To'] = self.emailconfig['to']
            
            with smtplib.SMTP(self.emailconfig['smtpserver'], 
                           self.emailconfig['smtpport']) as server:
                server.starttls()
                server.login(self.emailconfig['username'], 
                           self.emailconfig['password'])
                server.sendmessage(msg)
        except Exception as e:
            print(f"发送邮件失败: {e}")
    
    def monitorloop(self):
        """监控主循环"""
        while True:
            success,  = self.pinghost(self.target)
            timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
            
            if not success:
                self.failcount += 1
                if self.failcount >= 3:  # 连续失败3次触发告警
                    alertmsg = f"目标 {self.target} 连续Ping失败 {self.failcount} 次"
                    self.sendalert(alertmsg)
                    print(f"{timestamp} - 发送告警: {alertmsg}")
            else:
                self.failcount = 0
                
            time.sleep(60)
