Zabbix应用八:Zabbix监控MongoDB
利用Zabbix监控MongoDB一、首先介绍mongodb采集到的数据含义:
1、状态采集命令:
>db.serverStatus();
2、输出内容:
{"host" : "localhost","version" : "2.2.6","process" : "mongod","pid" : 55123,"uptime" : 18654536,"uptimeMillis" : NumberLong("18654536224"),"uptimeEstimate" : 18407100,"localTime" : ISODate("2017-07-10T08:06:17.628Z"),"locks" : {"." : {"timeLockedMicros" : {"R" : NumberLong(1203), #所有库全局读锁总微秒数"W" : NumberLong(1607)#所有全库局写锁总微妙数 },

zabbix监控页面的主要数据开源就是这里。
3、利用zabbix用户自定义监控功能userparameter 来监控MongoDB:
3.1、修改zabbix_agentd.conf，允许接受自定义参数:
UnsafeUserParameters=1
3.2、定义数据采集命令:
UserParameter=MongoDB.status
[*],/bin/echo "db.serverStatus().$1" |/data/mongodb/bin/mongo admin | grep "$2" | awk -F ':' '{print $$2}' | awk -F ',' '{print $$1}'
注意:不同环境，请注意主机ip和端口号等。
4、zabbix监控页面新建监控模版、添加监控项、生成图形:
创建模版:Template App MongoDB（已经手动创建完毕，并创建监控项，需要者可自行下载）
由于监控项众多，本例只贴出其中一个监控项的配置，如下图:
需要注意的是 键值 项，需和 UserParameter 中定义的格式一致。
5、模版创建完成后，套用到被监控的主机即可。
最终效果如下图:
