如何使用 Python 从 csv 列表中对设备进行 Ping 测试

Question

我正在尝试导入一个包含主机名的 csv 文件，并对大约 100 台设备进行 ping 测试。

CSV1:

Hostname  
abc  
bcd  
efg  
.  
.  
and so on

我想做 ping 测试，并在输出的 csv 文件中写入 ping 状态（UP 或 Down）以及相应的主机名。

像这样：

输出：

Hostname  Ping Status  
abc  UP  
bcd  DOWN  
efg  DOWN  
.  .  
.  .  
and so on

我已尽力在互联网上查找，但没有找到任何运气。我是 python 的新手，还处于学习阶段。请帮忙！！

import os
import csv

with open('CSV1.csv', 'r') as f:
    reader = csv.DictReader(f)
    rows = list(reader)

hosts = [row['CI_Name'] for row in rows]
statuses = [row['Status'] for row in rows]

for row in rows:
    #ping hosts
    hostname = row['CI_Name']
    response = os.system("ping -n 1 " + hostname)
    print ("[DEBUG]", response)
    if response == 0:
        print (hostname, 'is up')
        row['Status'] = 'Up'
    else:
        print (hostname, 'is down')
        row['Status'] = 'Down'

#write results
with open("Output Final.csv", "w") as w:
    writer = csv.writer(w)

我正在 Python 控制台中获取输出，它显示的 ping 详细信息与我们从 'CMD' 中获取的信息相同。但是我的输出 csv 文件没有受到影响。

这是代码的完整版本；尽管我仍在努力打印这些设备的 IP 地址，并在将其写入 csv 文件时获得正确的 headers。

import socket
import os
import csv
name = {}
CI = {}
hostname = {}
status = {}
with open('Output1.csv', 'r', newline='') as csvinput:
    reader = csv.DictReader(csvinput)

    for rows in reader:
        CI = rows['CI_Name']
        name = socket.getfqdn(CI)
        data = name
        hostname = rows['CI_Name']
        response = os.system('ping -n 2 ' + hostname)
        if response == 0:
            status = 'Up'
        else:
            status = 'Down'
        with open('Output Final.csv', 'a', newline='') as csvoutput:
            output = csv.writer(csvoutput)
            output.writerow([hostname] + [data] + [status])

Answer 1

#write results
with open("Output Final.csv", "w", newline='') as w:
    writer = csv.writer(w)
    writer.writerow(["CI_NAME","Status"])
    for r in rows:
        writer.writerow((r['CI_Name'], r['Status']))

Answer 2

最终修复了整个代码：

注意：我在这个脚本中集成了 nslookup、ping 测试和 ip 地址，通过传入我在 csv 文件中的设备列表来编写 FQDN、PING 测试和 IP 地址

import socket
import os
import csv
import subprocess
name = {}
CI = {}
hostname = {}
status = {}
with open('Output1.csv', 'r', newline='') as csvinput:
    reader = csv.DictReader(csvinput)

    for rows in reader:
        CI = rows['CI_Name']
        try:
            ip = socket.gethostbyname(CI)
        except socket.error:
            pass
        name = socket.getfqdn(CI)
        data = name

        hostname = rows['CI_Name']
        response = subprocess.Popen(['ping.exe',hostname], stdout = subprocess.PIPE).communicate()[0]
        response = response.decode()
        print(response)
        if 'bytes=32' in response:
            status = 'Up'
        elif 'destination host unreachable' in response:
            status = 'Unreachable'
        else:
            status = 'Down'
        if status == 'Down':
            ip = 'Not Found'
        with open('Output Final.csv', 'a', newline='') as csvoutput:
            output = csv.writer(csvoutput)
            output.writerow([hostname] + [data] + [status] + [ip])
