通过python脚本查看端口

[root@zabbix-server alertscripts]# cat check_port1.py
#!/usr/bin/env python
#coding:utf-8  

import os, json  

port_list=[]
port_dict={"data":None}
cmd='''''ss -tnlp|egrep -i "$1"|awk {'print $4'}|awk -F':' '{if ($NF~/^[0-9]*$/) print $NF}'|sort |uniq   2>/dev/null'''
local_ports=os.popen(cmd).readlines()  

for port in local_ports:
    pdict={}
    pdict["{#TCP_PORT}"]=port.replace("\n", "")
    port_list.append(pdict)  

port_dict["data"]=port_list
jsonStr = json.dumps(port_dict, sort_keys=True, indent=4)  

print jsonStr

　执行结果：

[root@zabbix-server alertscripts]# python check_port1.py
{
    "data": [
        {
            "{#TCP_PORT}": ""
        },
        {
            "{#TCP_PORT}": ""
        },
        {
            "{#TCP_PORT}": ""
        },
        {
            "{#TCP_PORT}": ""
        },
        {
            "{#TCP_PORT}": ""
        },
        {
            "{#TCP_PORT}": ""
        }
    ]
}
