zabbix 获取不到自定义脚本的值解决

agent端：

zabbix 自定义脚本

[root@localhost script]# cat check_ping.sh 
#!/bin/bash
result=$(/usr/local/nagios/libexec/check_icmp -s $1 $2)
a=$(echo $result | awk '{print $1}')
if [ $a == "OK" ];then
    echo "0000"
else
    echo "2222"
fi
[root@localhost script]# 

执行脚本：

[root@localhost script]# sh check_ping.sh 172.16.8.11 www.baidu.com
0000
[root@localhost script]# 
[root@localhost script]# sh check_ping.sh 172.16.8.11 www.nimeiakao.com
2222
[root@localhost script]

修改zabbix_agentd.conf配置并重启服务：

+++++++++++++
### Option: UnsafeUserParameters
#       Allow all characters to be passed in arguments to user-defined parameters.
#       0 - do not allow
#       1 - allow
#
# Mandatory: no
# Range: 0-1
# Default:
UnsafeUserParameters=1

### Option: UserParameter
#       User-defined parameter to monitor. There can be several user-defined parameters.
#       Format: UserParameter=<key>,<shell command>
#       See 'zabbix_agentd' directory for examples.
#
# Mandatory: no
# Default:
UserParameter=check.icmpping[*],/usr/local/zabbix/script/check_ping.sh $1 $2
++++++++++++++++++++++++++
[root@localhost etc]# /etc/init.d/zabbix_agentd restart
Shutting down zabbix_agentd:                               [  OK  ]
Starting zabbix_agentd:                                    [  OK  ]
[root@localhost etc]# 

在服务端使用命令检测自定义key是否可行：

[root@localhost ~]# zabbix_get -s 172.16.8.11 -p 10050 -k "check.icmpping[172.16.8.11,172.16.8.12]"
0000
[root@localhost ~]# zabbix_get -s 172.16.8.11 -p 10050 -k "check.icmpping[172.16.8.11,192.168.1.2]"
ZBX_NOTSUPPORTED
[root@localhost ~]# 
从上面可以看出，对于不通的值zabbix服务端始终取不到值，出现ZBX_NOTSUPPORTED

zabbix取不到值得解决办法：

修改agent端的超时时间并重启agent服务：

### Option: Timeout
#       Spend no more than Timeout seconds on processing
#
# Mandatory: no
# Range: 1-30
# Default:
#Timeout=3
Timeout=8
[root@localhost etc]# /etc/init.d/zabbix_agentd restart
Shutting down zabbix_agentd:                               [  OK  ]
Starting zabbix_agentd:                                    [  OK  ]
[root@localhost etc]# 

在server端再次测试：

[root@localhost ~]# zabbix_get -s 172.16.8.11 -p 10050 -k "check.icmpping[172.16.8.11,172.16.8.12]"
0000
[root@localhost ~]# zabbix_get -s 172.16.8.11 -p 10050 -k "check.icmpping[172.16.8.11,192.168.1.2]"
2222
[root@localhost ~]#
