Log4net buffer size not working

问题

im trying to enter every 100 records into the database.If i specify the buffer size as 100.It stills enters each record into the database.Is there a way where i can specify the flush interval and buffer size.So which comes first it takes that. This is my config.

回答1:

Buffersize only specifies how many items shall be kept in RAM before committing them. It does not define the Lossyness of the logger.

To define a lossy logger, you need to state that explicitly and define what can be lost:

<lossy value="true"/>
<evaluator type="log4net.Core.LevelEvaluator">
  <threshold value="ERROR" />
</evaluator>
