JSNLog.Log4Net Customization LOG

Question

in a project C# Web API + html/JS/JQuery, I'm currently using log4net logging library for information (server side).

Now, I need also to log information about client-side events.

I found the library JSNLog.Log4Net version: 2.20.1, and it seems to work.

My problem is that I need to custom log, as I'm doing with log4net.

Following the log4net.config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>

  <log4net>

    <appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
      <bufferSize value="0" />
      <reconnectOnError value="true"/>
      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

      <connectionString .... />

      <commandText value="INSERT INTO [INT].[Log] ([Appl],[Level],[IP],[HttpMethod],[API],[Request],[DataInput],[Response],[DataOutput],[UserName],[Message],[Exception],[ExecutedTime])

</configuration>

following, an example of what I'm log:

As you can see, the yellow line (the one generated by JSNLog.log4net) lack much information.

How do I add them?

PS .: If necessary, I can also change library for client-side logging.

Answer 1

The missing entries are the %property{X} ones, which the client side library cannot access, as they are held in memory on the server. If you want to log them from the client side, you will need to pass the property values through to it.
