How to enable internal log4net debug logging in Spotfire Web Player.

How to enable internal log4net debug logging in Spotfire Web Player:

1). Follow the instructions in section the Spotfire Server documentation to export the default service configuration:

config export-service-config --capability=WEB_PLAYER--deployment-area=Production

Documentation reference: https://docs.tibco.com/pub/spotfire_server/14.6.1/doc/html/TIB_sfire_server_tsas_admin_help/server/topics/manually_editing_the_service_configuration_files.html

2). Edit the Spotfire.Dxp.Worker.Host.exe.config file. Below the tag applicationSettings add the following (if not already present):

<system.diagnostics>
    <trace autoflush="true">
      <listeners>
        <add
            name="textWriterTraceListener"
            type="System.Diagnostics.TextWriterTraceListener"
            initializeData="C:\temp\logs\log4net.txt" />  <!-- Use a path that exists -->
      </listeners>
    </trace>
  </system.diagnostics>

  <appSettings>
    <!-- Do not edit these settings if you are not really sure what you are doing!
         To enable log4net debug logging, set Quiet=false and Debug=true -->
    <add key="log4net.Internal.Quiet" value="false" />
    <add key="log4net.Internal.Debug" value="true" />
  </appSettings>

Make sure to set the initializeData path to where you want the log4net debug log be written to. 

3). Import the updated config to a new name by following follow the instructions in section the Spotfire Server documentation: 

config import-service-config --config-name=ServiceConfiguration
