Note - there is an experimental update in the FinalLiteDB4.x branch. Current plan is to migrate this to master as the last version supporting LiteDB 4.x versions. Test the latest version and open up any 'issues' you have with it. Migration, and the introduction of a new project targeting LiteDB 5.x support is scheduled for early 2021.
NLog target for the LiteDB database
Examples below for the 4 connection string types:
<targets>
<!-- Legacy Target still supported-->
<target name="legacy" xsi:type="liteDBTarget"
connectionString="filename=NLog.db"
collectionName="DefaultLog">
<property name="ThreadID" layout="${threadid}" bsonType="Int32" />
<property name="ThreadName" layout="${threadname}" />
<property name="ProcessID" layout="${processid}" bsonType="Int32" />
<property name="ProcessName" layout="${processname:fullName=true}" />
<property name="UserName" layout="${windows-identity}" />
</target>
<target name="special" xsi:type="liteDBTarget"
connectionString="special={MyDocuments}\testApp\NLog.db"

</target>
</targets>
<rules>
<logger name="*" minlevel="Trace" maxlevel="Debug" writeTo="special" />
<logger name="*" minlevel="Info" maxlevel="Warn" writeTo="path" />
<logger name="*" minlevel="Error" maxlevel="Fatal" writeTo="file" />
</rules>name - Name of the target.
connectionName - The name of the connection string to get from the config file.
connectionString - 4 connection string types are permitted.
- Special - this allows for the connection string to utilize special folders - Refer to Microsoft documentation on Environment.SpecialFolder Enum for a full list. They are case sensitive.
- Path - as this suggests - a file path.
- File - just a base filename.
- Legacy - for backwards compatiblity.
collectionName - The name of the LiteDB collection to write logs to.
IsJournaling - Journaling is enabled by default. Specify IsJournaling="false" to disable LiteDB journaling.
includeDefaults - Specifies if the default document is created when writing to the collection. Defaults to true.
field - Specifies a root level document field. There can be multiple fields specified.
property - Specifies a dictionary property on the Properties field. There can be multiple properties specified.
