Zabbix應用八:Zabbix監控MongoDB

利用Zabbix監控MongoDB

 

一、首先介紹mongodb采集到的數據含義:

1、狀態采集命令:

>db.serverStatus();

2、輸出內容:

    "ok" : 1
}

 zabbix監控頁面的主要數據開源就是這里。 

 3、利用zabbix用戶自定義監控功能 userparameter 來監控MongoDB:

 　　3.1、修改zabbix_agentd.conf，允許接受自定義參數:

UnsafeUserParameters=1

　　3.2、定義數據采集命令:

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:不同環境，請注意主機ip和端口號等。

4、zabbix監控頁面新建監控模版、添加監控項、生成圖形:

創建模版:Template App MongoDB（已經手動創建完畢，並創建監控項，需要者可自行下載）

由於監控項眾多，本例只貼出其中一個監控項的配置，如下圖:

需要注意的是 鍵值 項，需和 UserParameter 中定義的格式一致。

5、模版創建完成后，套用到被監控的主機即可。

最終效果如下圖:
