Zabbix yum安装参考:https://www.tracymc.cn/archives/614,编译安装可参考https://www.tracymc.cn/archives/218.
mongodb安装:https://www.tracymc.cn/archives/492,https://www.tracymc.cn/archives/168

具体步骤:
1.编写脚本并设置键值
监控脚本:
[root@test ~]# cat /etc/zabbix/scripts/mongodb.sh
#!/bin/bash

index=$(echo $@ | tr " " ".")
status=$(echo "db.serverStatus().${index}" |/usr/bin/mongo --quiet admin)

#check if the output contains "NumberLong"

if [[ "$status" =~ "NumberLong" ]];then
echo $status|sed -n 's/NumberLong(//p'|sed -n 's/)//p'
else
echo $status
fi
[root@test zabbix_agentd.d]# chmod u+x /etc/zabbix/scripts/mongodb.sh //设置权限
设置键值:
[root@test ~]# cat /etc/zabbix/zabbix_agentd.conf |grep conf|grep -v ‘#’ //yum安装zabbix的话agent默认配置文件为/etc/zabbix/zabbix_agentd.conf
Include=/etc/zabbix/zabbix_agentd.d/*.conf //你懂的,包含/etc/zabbix/zabbix_agentd.d下面的配置
[root@test zabbix_agentd.d]# cat /etc/zabbix/zabbix_agentd.d/userparameter_mongodb.conf
UserParameter=mongodb.status[*],sudo sh /etc/zabbix/scripts/mongodb.sh $1 $2 $3 $4 $5
[root@test zabbix_agentd.d]# systemctl restart zabbix-agent //重启agent

[root@test zabbix_agentd.d]# visudo //增加如下行
zabbix ALL=(ALL) NOPASSWD:/bin/sh

2.下载模板
模板地址:zbx_mongodb_templates

3.导入模板
先将模板存到本地,再导入到zabbix-server中.
导入下载模板,如下:

导入成功后可以在配置-模板查看已导入的模板,如下:

4.关联模板
添加模板:
配置-主机点击相关主机进去配置模板,如下:

5.zabbix web验证是否有数据
关联模板后,稍等一会,查看web页面是否有数据.
部分截图如下:

注意:
一开添加模板后出不来数据,有如下报错:
Value "995 2018-06-14T16:45:51.388+0800 E - [main] Error saving history file: FileOpenFailed: Unable to open() file .dbshell: Permission denied" of type "string" is not suitable for value type "Numeric (unsigned)"
意思是zabbix用户没有权限打开.dbshell(全路径为/root/.dbshell)这个文件,解决办法:
[root@test zabbix_agentd.d]# visudo //增加如下行
zabbix ALL=(ALL) NOPASSWD:/bin/sh
