zabbix3.2监控mongodb

模板地址：https://share.zabbix.com/databases/mongodb/mongodb-for-zabbix-3-2

1.安装jq依赖
# yum install jq -y

2.添加监控用户
# 使用admin登录mongo
[root@eus_pe_web02:/usr/local/zabbix_agents_3.2.0/scripts]# mongo
MongoDB shell version v3.4.6
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.6
> use admin
> db.auth('admin','admin')

# 在admin高权限用户下授权monitor用户，改用户专门用来给zabbix提供监控数据
>db.createUser(
{
user: "zabbix",
pwd: "zabbix",
roles: [
{ role: "clusterMonitor", db: "admin" }
]
}
)

3.修改脚本
[root@eus_pe_web02:/usr/local/zabbix_agents_3.2.0/scripts]# cat /usr/local/zabbix_agents_3.2.0/scripts/mongodb.sh 
#!/bin/bash

4.添加配置文件
# vim /usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd/userparameter_mongodb.conf
# Return MongoDB statistics
UserParameter=mongodb.status[*],/usr/local/zabbix_agents_3.2.0/scripts/mongodb.sh  $1 $2 $3 $4 $5

5.导入模板
