Nlog -Mongodb创建集合

问题描述

我正在使用Nlog（4.7.5），Nlog.mongo（4.6.0.118）和mongoDB.Driver（2.11.3）。 使用mongodb登录时，我需要创建如下 "log-2020-10-18" 这样的集合。 因此，第18个日期日志存储在此集合中。第二天等的日志将存储在 "log-${shortdate}" 集合中。日志每天都以集合名称的格式存储。 简而言之，我想每天将日志存储在mongodb.so中，因此很容易查看日常日志。 我可以在运行时创建集合（我的意思是在nlog.config文件中） 这样做有可能吗？怎么样？

这是mongodb目标

    <target xsi:type="Database"
                    name="mongo"
                    includeDefaults="false"
                    connectionString="mongodb://localhost/financeLogs"
                    collectionName="log-${shortdate}"
                    databaseName="financeLogs">
                <property name="LongDate" layout="${longdate}" bsonType="DateTime" />
                <property name="Level" layout="${level}"/>
                <property name="Message" layout="${message}"/>
    
            </target>

解决方法

您是否尝试过此操作（请注意使用xsi:type="Mongo"）

    <target xsi:type="Mongo"
            name="mongo"
            includeDefaults="false"
            connectionString="mongodb://localhost/financeLogs"
            collectionName="log-${shortdate}"
            databaseName="financeLogs">
        <property name="LongDate" layout="${longdate}" bsonType="DateTime" />
        <property name="Level" layout="${level}"/>
        <property name="Message" layout="${message}"/>
    </target>

请确保使用https://www.nuget.org/packages/NLog.Mongo/4.6.0.123（或更高版本）以更好地支持在${shortdate}中使用collectionName=
