zabbix监控网站黑链接及数据推送

1.检测脚本

1》编写python脚本

创建脚本check_black_links.py，使用python脚本实现网站黑链接检测；

首先，确保你的环境中已经安装了 Python 和 requests 以及 beautifulsoup4 库。没有安装请使用pip安装；

#!/usr/bin/env python3

import requests
from bs4 import BeautifulSoup
import sys

def check_links(url):
    try:
        response = requests.get(url)
        response.raise_for_status()
    except requests.exceptions.RequestException as e:
        return f"Error accessing {url}: {e}"

    soup = BeautifulSoup(response.content, 'html.parser')
    bad_links = []

    for link in soup.find_all('a', href=True):
        link_url = link['href']
        if link_url.startswith('#'):  # Skip internal page references
            continue

        if not link_url.startswith(('http://', 'https://')):
            link_url = requests.compat.urljoin(url, link_url)  # Join relative URLs to base URL

        try:
            link_response = requests.head(link_url, allow_redirects=True)
            if link_response.status_code != 200:
                bad_links.append(f'URL: {link_url}, Status Code: {link_response.status_code}')
        except requests.exceptions.RequestException as e:
            bad_links.append(f'URL: {link_url}, Error: {e}')

    if bad_links:
        return f"Found bad links: {', '.join(bad_links)}"
    else:
        return "All links are working properly."

if __name__ == "__main__":
    if len(sys.argv) != 2:
        print("Usage: check_black_links.py <URL>")
        sys.exit(1)

    url = sys.argv[1]
    result = check_links(url)
    print(result)

2》脚本执行

#将脚本上传到服务器
格式：执行脚本语言	脚本	检测网站 
python check_black_links.py https://www.cnblogs.com

案例：

# 这里将脚本上传到zabbix的存放脚本目录，检测网站为博客园
python /usr/lib/zabbix/externalscripts/check_black_links.py https://www.cnblogs.com

# 输出如下，这里挑选出部分日志粘贴
Found bad links: URL: https://www.cnblogs.com/cmt/p/18341478, Status Code: 400, URL: https://wz.cnblogs.com/, Status Code: 405, URL: javascript:void(0), Error: No connection adapters were found for 'javascript:void(0)', URL: javascript:void(0), Error: No connection adapters were found for 'javascript:void(0)', URL: javascript:void(0), Error: No connection adapters were found for 'javascript:void(0)', URL: javascript:void(0), Error: No connection adapters were found for 'javascript:void(0)', URL: https://www.cnblogs.com/cmt/articles/18197617, Status Code: 400, URL: https://wz.cnblogs.com/, Status Code: 405, URL: javascript:void(0), Error: No connection adapters were found for 'javascript:void(0)', URL: javascript:void(0), Error: No connection adapters were found for 'javascript:void(0)', URL: javascript:void(0), Error: No connection adapters were found for 'javascript:void(0)', URL: https://www.cnblogs.com/wzh2010/p/18031157, Status Code: 400, URL: https://www.cnblogs.com/Can-daydayup/p/18457705, Status Code: 400, URL: https://www.cnblogs.com/shanyou/p/18457208, Status Code: 400, URL: https://www.cnblogs.com/cmt/p/18453394, Status Code: 400, URL: https://www.cnblogs.com/cmt/p/18453394, Status Code: 400, URL: https://www.cnblogs.com/Ke-Xin-Jsy/p/18458915, Status Code: 400, URL: https://www.cnblogs.com/Ke-Xin-Jsy/p/18458915#commentform, Status Code: 400, URL: javascript:void(0), Error: No connection adapters were found for 'javascript:void(0)', URL: https://www.cnblogs.com/Ke-Xin-Jsy/p/18458915, Status Code: 400, URL: https://www.cnblogs.com/michaelho/p/18458914, Status Code: 400, URL: https://www.cnblogs.com/michaelho/p/18458914#commentform, Status Code: 400

2.数据推送

1》方案一

通过agent推送，适用于执行时间短的脚本推送

# 编辑agent配置文件“zabbix_agentd.conf”，配置UserParameter推送；（注：适合数据小，执行时间短的脚本，执行时间不得大于15s）

vim /etc/zabbix/zabbix_agentd.conf
UserParameter=check.blacklinks[*],/usr/bin/python /usr/lib/zabbix/externalscripts/check_black_links.py $1


# 登录zabbix web页面-->选择监控主机-->创建监控项-->选择监控类型为agent-->选择自定义key（check.blacklinks["https://www.cnblogs.com"]）-->选择信息类型为文本-->保存监控项-->最新数据检查数据

2》方案二

通过zabbix sender推送，适用于执行时间长的脚本推送

# 编写执行推送脚本，可通过crontab来定期推送数据（注：数据大小不定，执行时间长的脚本，执行时间大于15s可选择此方式）

# 登录zabbix web页面-->选择监控主机-->创建监控项-->选择监控类型为trapper-->选择自定义key（zbx.sender）-->选择信息类型为文本-->保存监控项-->最新数据检查数据

创建推送数据脚本zabbix_sender_check_black_links.sh

#!/bin/bash

# Zabbix server details
ZABBIX_SERVER="10.11.12.13"
ZABBIX_PORT="10051"
ZABBIX_HOST="Zabbix server test"
ZABBIX_KEY="zbx.sender"

# Call the Python script and get the output
BLACK_LINKS_COUNT=$(python /usr/lib/zabbix/externalscripts/check_black_links.py https://www.cnblogs.com)

# Use zabbix-sender to send the data to Zabbix server
/usr/bin/zabbix_sender -z "$ZABBIX_SERVER" -p "$ZABBIX_PORT" -s "$ZABBIX_HOST" -k "$ZABBIX_KEY" -o "$BLACK_LINKS_COUNT" >/dev/null

crontab编写，定期执行脚本推送数据

# 登录服务器定期执行脚本
crontab -l
1 * * * * /usr/bin/bash /usr/lib/zabbix/externalscripts/zabbix_sender_check_black_links.sh
