Zabbix监控Linux服务的自动发现

GOnetstat.Tcp()
GOnetstat.Udp()

package main

import (
	"encoding/json"
	"fmt"
	"github.com/drael/GOnetstat"
	"log"
)

type Process struct {
	Name string `json:"{#PROCNAME}"`
	Port int64  `json:"{#PORT}"`
}

type ZabbixData struct {
	Data []Process `json:"data"`
}

func main() {
	data := GOnetstat.Tcp()
	var zd = new(ZabbixData)

	for _, p := range data {
		if p.State == "LISTEN" {
			zd.Data = append(zd.Data, Process{p.Name, p.Port})
		}
	}

	output, err := json.MarshalIndent(zd, "", "    ")
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(string(output))
}

编译为tcp_services,放到/usr/bin/目录下，并赋予执行权限

cp tcp_services /usr/bin/
chmod +x /usr/bin/tcp_services

测试

[root@proxy bin]# /usr/bin/tcp_services
{
    "data": [
        {
            "{#PROCNAME}": "Master",
            "{#PORT}": 25
        },
        {
            "{#PROCNAME}": "Ruby",
            "{#PORT}": 24224
        },
        {
            "{#PROCNAME}": "Zabbix_agentd",
            "{#PORT}": 10050
        },
        {
            "{#PROCNAME}": "Zabbix_proxy",
            "{#PORT}": 10051
        },
        {
            "{#PROCNAME}": "Ruby",
            "{#PORT}": 24230
        },
        {
            "{#PROCNAME}": "Snmpd",
            "{#PORT}": 199
        },
        {
            "{#PROCNAME}": "Svnserve (Deleted)",
            "{#PORT}": 3690
        },
        {
            "{#PROCNAME}": "Nginx",
            "{#PORT}": 80
        },
        {
            "{#PROCNAME}": "Sshd",
            "{#PORT}": 22
        },
        {
            "{#PROCNAME}": "Ruby",
            "{#PORT}": 8888
        }
    ]
}

有以上返回，说明程序工作正常
我已编译好，大家可下载

2.设置zabbix_agentd

编辑zabbix_agentd.conf
添加如下

UserParameter=udp_services, sudo /usr/bin/tcp_services

同时编辑，/etc/sudoers.d/zabbix

vi /etc/sudoers.d/zabbix
Defaults:zabbix !requiretty
zabbix ALL=NOPASSWD: /usr/bin/tcp_services

我就添加一个tcp的，udp的可照着添加一个就可以了，添加好之后重启zabbix_agentd

3.zabbix设置

zabbix里导入模版，导入之后，添加模版到主机

触发器

4.Debug

A.检查是否关闭SElinux
B.在zabbix_server上执行操作（IP_DO_SERVIDOR_MONITORADO为被监控端ip

zabbix_get -s IP_DO_SERVIDOR_MONITORADO -k "tcp_services"

例如

[root@canghai bin]# ./zabbix_get -s 192.168.1.10  -k "tcp_services"
{
    "data": [
        {
            "{#PROCNAME}": "Master",
            "{#PORT}": 25
        },
        {
            "{#PROCNAME}": "Ruby",
            "{#PORT}": 24224
        },
        {
            "{#PROCNAME}": "Zabbix_agentd",
            "{#PORT}": 10050
        },
        {
            "{#PROCNAME}": "Zabbix_proxy",
            "{#PORT}": 10051
        },
        {
            "{#PROCNAME}": "Ruby",
            "{#PORT}": 24230
        },
        {
            "{#PROCNAME}": "Snmpd",
            "{#PORT}": 199
        },
        {
            "{#PROCNAME}": "Svnserve (Deleted)",
            "{#PORT}": 3690
        },
        {
            "{#PROCNAME}": "Nginx",
            "{#PORT}": 80
        },
        {
            "{#PROCNAME}": "Sshd",
            "{#PORT}": 22
        },
        {
            "{#PROCNAME}": "Ruby",
            "{#PORT}": 8888
        }
    ]
}

如返回数据说明没有问题，不返回则说明zabbix_agentd或者tcp_service有问题。
