Python 开发简易巡检工具

分类：Python作者：lyshark

利用SSH或者Zabbix监控，配合Django开发框架，改造出属于自己的监控平台，实现包括主机图形，自动发现，计划任务，批量cmd执行，服务监控，日志监控等功能，由于公司机器混乱，基本上市面上的所有设备都能找到，监控这些不同型号不同系统的主机需要分别对待，我们就借助各种开源项目来做一个简单的巡检工具，方便工作需要。

由于公司及其都是老式的性能不高，所以全程我都没敢加多线程，生怕把服务器拒绝服务了。

安装Zabbix客户端

首先客户端还是需要安装zabbix-agent这个监控工具，该工具可以监控所有的平台，windows linux mac unix 等，利用该工具完成一整套自动化平台一点问题都没有，连ansible都不需要了。

[root@localhost ~]# wget http://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-agent-4.4.3-1.el7.x86_64.rpm
[root@localhost ~]# rpm -ivh zabbix-agent-4.2.0-0.1alpha1.el7.x86_64.rpm

该配置文件，并启动服务完事。

[root@localhost ~]# vim /etc/zabbix/zabbix_agentd.conf

PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=192.168.1.2
ServerActive=192.168.1.2
Hostname=centos1
Timeout=1
Include=/etc/zabbix/zabbix_agentd.d/*.conf
EnableRemoteCommands=1

[root@localhost ~]# systemctl restart zabbix-agent
[root@localhost ~]# systemctl enable zabbix-agent

服务端下载

https://www.zabbix.com/cn/download_agents

下载好之后将里面的 zabbix-get.exe 拖入项目中，直接调用就好。

基本的数据采集命令：

zabbix_get.exe -s 192.168.1.20 -p 10050 -k system.hostname
localhost.localdomain  // 此处才是主机名称

zabbix_get.exe -s 192.168.1.20 -p 10050 -k agent.hostname

比较好的改进写法

上方代码中每个表都有一份账号密码，很麻烦，第二次重写我通过一个UUID序号，来定位用户名密码等登录信息，然后在一个配置文件中包含了所有配置项，程序中对不同的项目进行解析，来实现一个配置文件配置所有的配置项，只有基础base结构存储账号密码，每个base结构对应一个UUID号，当添加进程等表时，自动根据UUID号码，来解析账号密码，这样通过序号关联，只需写一份密码即可，通过UUID相关联。


使用Django开发图形化界面

收集目标主机数据的类:

import os,math

class GetSysInfo(object):
    def __init__(self,addr,port):
        self.addr = addr
        self.port = port
    def GetHostName(self):
        try:
            Command = "get.exe -s {} -p {} -k system.hostname".format(self.addr,self.port)
            proc = subprocess.Popen(Command,stderr=subprocess.PIPE)

            InModule = int(InModule.stdout.readlines()[0].split()[0])
            OutModule = subprocess.Popen("get.exe -s {} -p {} -k net.if.out[ens32,stderr=subprocess.PIPE)
            OutModule = int(OutModule.stdout.readlines()[0].split()[0])
            return InModule,OutModule
        except Exception:
            return 0


a = GetSysInfo("192.168.1.20","10050")
b = a.GetNetInfo()
print(b)

admin.py

from django.contrib import admin
from MyWeb.models import *

@admin.register(HostInfo)
class MyAdmin(admin.ModelAdmin):
    list_display = ("HostAddr","HostName","HostCPU","HostMem","HostDisk","HostNet")

models.py

from django.db import models

class HostInfo(models.Model):
    id = models.AutoField(primary_key = True)
    HostAddr = models.CharField(max_length=64,verbose_name="主机地址")
    HostName = models.CharField(max_length=64,verbose_name="主机名称")
    HostCPU = models.CharField(max_length=64,verbose_name="CPU利用率")
    HostMem = models.CharField(max_length=64,verbose_name="内存数据")
    HostDisk = models.CharField(max_length=64,verbose_name="磁盘空闲")
    HostNet = models.CharField(max_length=64,verbose_name="网卡流量")

先来判断是否有指定的IP地址，有的话后端直接爬取数据并填充到数据库中，要求是只需要输入IP地址即可取出所有的数据，并自动填充，有几台自动填充几台。

if __name__ == "__main__":
    conn = sqlite3.connect("C:/Users/LyShark/PycharmProjects/MyProject/db.sqlite3")
    cursor = conn.cursor()
    cursor.execute('select * from MyWeb_hostinfo;')
    data = cursor.fetchall()

    for item in range(0,len(data)):
        addr = data[item][1]
        info = GetSysInfo(addr,"10050")
        print(info.GetNetInfo())

fabric的使用技巧 fabric工具也是自动化运维利器,其默认依赖于paramiko的二次封装.

# 简单实现命令执行
from fabric import Connection
conn = Connection(host="192.168.1.10",user="root",port="22",connect_kwargs={"password":"123"})
try:
    with conn.cd("/var/www/html/"):
        ret = conn.run("ls -lh",hide=True)
        print("主机:" + conn.host + "端口:" + conn.port + "完成")
except Exception:
    print("主机:" + conn.host + "端口:" + conn.port + "失败")

# 读取数据到本地
from fabric import Connection
conn = Connection(host="192.168.1.20",connect_kwargs={"password":"123"})

uname = conn.run('uname -s',hide=True)
if 'Linux' in uname.stdout:
    command = "df -h / | tail -n1 | awk '{print $5}'"
    print(conn.run(command,hide=True).stdout.strip())

# 文件上传与下载
from fabric import Connection
conn = Connection(host="192.168.1.20",connect_kwargs={"password":"123"})
conn.put("D://zabbix_get.exe","/tmp/zabbix.exe")  # 文件上传
conn.get("/tmp/zabbix.exe","./zab.exe")           # 下载文件
