zabbix 自定义 key （转）

1、在zabbix_agent端zabbix_agentd.conf配置文件中增加自定义Key(/usr/local/zabbix_agent/etc/zabbix_agentd.conf)

### 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接
# Default:
# UserParameter=

UserParameter=Physical_cpu_0_temperature,sensors|grep "id 0"|awk ‘{print $4}‘|awk -F "°" ‘{print $1}‘|awk -F "+" ‘{print $2}‘

     变量    Key                                命令

就样一个自定义的Key就完成了，那么我们要怎么来测试这个Key是否生效了呢？配置文件修改完成后需要重启zabbix_agentd端的服务，然后在zabbix_server端通过zabbix_get查看，是否可以获取到值，如果获取到值，表明这个Key就设置成功了。

设置完Key一定记得要通过命令进行验证啊！！！

# zabbix_get -s 10.16.1.201 -p 10050 -k Physical_cpu_0_temperature
59.0

我们看下，CPU的温度已经可以正常获取了，我们的key就设置成功了！

说了第一种定义Key的方法，是在zabbix_agend.conf的主配置文件中修改，大家可以想想，如果需要定义100个Key的话，都写在主配置文件里，是不是主配置文件会很乱啊，那我们来看看有什么更好的方法呢，接下来看看第二种方法吧！

2、将Key定义在独立的文件中，然后在主配置文件中进行新引用就好了，下面我们来配置下。

2.1 修改zabbix_agentd.conf 配置（/usr/local/zabbix_agent/etc/zabbix_agentd.conf）

cat /usr/local/zabbix_agent/etc/zabbix_agentd.conf      # 在zabbix_agentd.conf配置文件中通过Include引用自定义Key文件目录

### Option: Include
#       You may include individual files or all files in a directory in the configuration file.
#       Installing Zabbix will create include directory in /usr/local/etc, unless modified during the compile time.
#
# Mandatory: no
# Default:
# Include=
# Include=/usr/local/etc/zabbix_agentd.userparams.conf
Include=/usr/local/zabbix_agent/etc/zabbix_agentd.conf.d/

2.2 在/usr/local/zabbix_agent/etc/zabbix_agentd.conf.d目录写编写自定义Key文件

# cat custom_parameters.conf
# Monitor CPU temperature
# cpu_core_0
UserParameter=Physical_cpu_0_temperature,sensors|grep "id 0"|awk ‘{print $4}‘|awk -F "°" ‘{print $1}‘|awk -F "+" ‘{print $2}‘
UserParameter=cpu_0_core0,sensors|grep -A 6 "id 0" | grep "Core 0" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_0_core1,sensors|grep -A 6 "id 0" | grep "Core 1" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_0_core2,sensors|grep -A 6 "id 0" | grep "Core 2" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_0_core3,sensors|grep -A 6 "id 0" | grep "Core 3" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_0_core4,sensors|grep -A 6 "id 0" | grep "Core 4" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_0_core5,sensors|grep -A 6 "id 0" | grep "Core 5" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘

# cpu_core_1
UserParameter=Physical_cpu_1_temperature,sensors|grep "id 1"|awk ‘{print $4}‘|awk -F "°" ‘{print $1}‘|awk -F "+" ‘{print $2}‘
UserParameter=cpu_1_core0,sensors|grep -A 6 "id 1" | grep "Core 0" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_1_core1,sensors|grep -A 6 "id 1" | grep "Core 1" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_1_core2,sensors|grep -A 6 "id 1" | grep "Core 2" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_1_core3,sensors|grep -A 6 "id 1" | grep "Core 3" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_1_core4,sensors|grep -A 6 "id 1" | grep "Core 4" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘
UserParameter=cpu_1_core5,sensors|grep -A 6 "id 1" | grep "Core 5" | awk ‘{print $3}‘|awk -F "°" ‘{print $1}‘|awk  -F "+" ‘{print $2}‘

这让定义就可以了，如果需要定义的Key较多的话，我们就可以通过这种方式来定义key了，这样做的好处大家也可以很清楚的看到了，配置清晰、明了，而且不和主配置文件在一起，避免修改key影响主配置文件哈。记得修改完配置文件，记得重启zabbix_agent服务啊。最好还要通过上面介绍的方法进行验证下啊。

Key定义好了，我们来看看，如何在zabbix web页面通过这些来创建监控项吧！
