操作一個數據庫，日誌非常重要，定位問題幾乎時時刻刻用到。所以如何配置，如何獲取日誌應該成爲必備技能。以下蒐集了一些參考資料，可以通過以下資料明白自己搭建MongoDB服務器如何配置日誌及級別等，利於學習及備份。
舉例一個稍微奇葩的應用場景，有一天某表數據莫名被刪了，恢復後又莫名被刪了，如果沒人出來迴應，有涉及到多個產品線，上百號人，那通過日誌即使沒人承認，也是非常快地可以知道是誰幹的，是人乾的還是程序乾的。
其他的使用場景還有非常多，就不一一舉例了。
mongod.cfg配置文件樣例
#注意，縮進不對可能解析時會報錯
systemLog:
#0到5，默認0
verbosity: 1
destination: file
path: D:\app\tools-install\MongoDB\log\mongoserver.log
logAppend: true
component:
accessControl:
verbosity: 2
command:
verbosity: 2
# COMMENT some component verbosity settings omitted for brevity
write:

query:

index:

network:

executor:

verbosity: 2
storage:
journal:
enabled: true
dbPath: D:\app\tools-install\MongoDB\data\db
net:
port: 27017
#security:
#authorization: enabled
除了在MongoDB配置文件配置外，還可以使用命令臨時設置日誌級別
db.getLogComponents();//查看
db.setLogLevel(2);//設置
db.setLogLevel(2, "command" );//command具體設置
db.setLogLevel(2, "query" );
db.setLogLevel(2, "write" );
db.setLogLevel(2, "index" );
db.setLogLevel(2, "network" );
db.setLogLevel(2, "executor" );
db.setLogLevel(2, "control" );
db.setLogLevel(2, "accessControl" );
