Zabbix 监控mongodb数据库状态 - Martin.xu

公告

为了能实时了解运行的状态，需要增加zabbix对mongodb的运行状态监控。

mongodb默认安装情况下可以运行

echo "db.serverStatus()" | mongo 来获取mongodb的运行状态

[root@localhost ~]# echo "db.serverStatus()" | mongo 127.0.0.1:30000

因此可以考虑使用zabbix的UserParameter自定义监控，对MongoDB进行监控

添加MongoDB监控

1、zabbix客户端配置文件zabbix_agentd.conf文件，添加如下内容：

UserParameter=MongoDB.Status[*],/bin/echo "db.serverStatus().$1" | /usr/bin/mongo  127.0.0.1:30000 | grep "$2"|awk -F: '{print $$2}'|awk -F, '{print $$1}'

上面是通过db.serverStatus()来获取服务器状态

其中$1表示第一个参数

grep $2的时候要加上锚地符 "\<" 和 "\>"，因为有的对象名可能部分相同

使用自定义的命令测试获取的结果

[root@mongodb bin]# echo "db.serverStatus().opcounters" | mongo admin

MongoDB shell version: 2.6.3
connecting to: admin
{
       "insert" : 6,
       "query" : 138,
       "update" : 1,
       "delete" : 1,
       "getmore" : 0,
       "command" : 9884
}
