Python编写从ZabbixAPI获取信息

此脚本用Python3.6执行是OK的。

下面看下使用python实现 Zabbix-API 监控的方法

做运维的朋友应该知道，公司IDC机房经常有上架、下架、报修和报废的服务器。如果服务器数量很多的时候很容易造成监控遗漏。
大的互联网公司把监控系统和CMDB(资产管理系统|配置管理数据库系统)集成在一起，当上架一台新机器的时候CMDB里面会记录相关的信息，Zabbix根据CMDB里面信息自动Link相关的模块，添加|删除监控。很多小的公司没有资产管理系统，但作为监控的负责人应该每天知道上架了哪些新的机器，确保能添加到Zabbix监控里面。
首先给大家说一下脚本思路：
1)通过Nmap工具扫描网段，扫描出已经使用的IP地址。
2)通过Nmap检测已经扫描IP的3389或者22端口是否开放，可以判断那些事windows机器，那些是Linux机器。
3)Linux下面通过ssh + hostname命令找出Linux主机名。
4)Windows下面通过nmblookup -A 命令找出Windows主机名。
5)用Python脚本读扫描结果文件，把主机名写到列表里面。
6)用Zabbix python API 调用已经监控的主机名，写到列表里面。
7)两个列表取交集，用for循环判断哪些主机名没有监控。
8)发邮件通知监控负责人。
下面我分享一下我写的Python写的脚本，其中scan_machine.sh是我调用的用Shell写的关于Nmap扫描的脚本，scan_hostname.log是Nmap扫描的结果，里面内容是IP 主机名。

zbxhosts=host['name']
zabbixhostlst.append(zbxhosts)
zabbixhostlst.sort()
return zabbixhostlst def main():
nmaphostlst = nmap_host()
zbxhostlst = zabbix_host()
diff = list(set(nmaphostlst) ^ set(zbxhostlst))

nomonitorlst = []
if len(diff) != 0:
for host in diff:
if host in nmaphostlst:
nomonitorlst.append(host)
else:
sys.exit()
#print zbxhostlst
string = 'n'.join(nomonitorlst)
f = file('/shell/machine/result/result.txt','w')
f.write(string)
f.flush()
f.close()
runCmd(mail_cmd)if __name__ == "__main__":
main()

把脚本添加到crontab,每台会收到关于那些主机没有添加监控的信息。

总结：

2)通过该脚本可以知道那些主机没有添加监控，希望对大家有帮助，如果有更好的解决方法欢迎多多交流。
