Problem with Logging.

Vote:
 

Hi ,

I've created a log4net appender which stores all the information (level set to 'ALL') by following this link https://world.episerver.com/documentation/Items/Developers-Guide/Episerver-CMS/75/Logging/logging-with-log4net/ . I want to write the log to another text file in my local drive. Can someone tell me the process to do that?

Thanks in advance.

Hi,

I'd look at some log4net troubleshooting to see why log4net isn't logging.

Phil Haack has an old, but still valid blog post at http://haacked.com/archive/2006/09/27/Log4Net_Troubleshooting.aspx/

The TL;DR:

First, enable internal log4net debugging: Add the following to your appSettings in web.config:

<add key="log4net.Internal.Debug" value="true"/>

Then, enable system diagnostics trace. Add  the following to your web.config:

<system.diagnostics>
<trace autoflush="true">
<listeners>
<add name="textWriterTraceListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="C:\tmp\log4net.txt" />
</listeners>
</trace>
</system.diagnostics>

Just remember to change the path in the "initializeData" attribute.

Hi Øyvind,

I'm getting the logs in different text file. A part of the log file looks like :

I tried changing the content in CMS mode(On page edit mode) and i got an render exception, but that is not logged in the file.Can On page edit errors be logged? If so how can i  log them into the file?

I should get the log in the following format : 2017-08-08 16:33:26,034 [9] INFO LogFile: Log created now ! . What is the content that i'm getting in the above link ?

For rendering exception, check out if you have a custom content area renderer. I seem to recall there is one in Alloy demo project and that one also has a try catch that swallows exceptions without logging them. I usually add a line to log those rendering exceptions there.

Hi Daniel, actually I got the rendering exception to be logged in the format I  wanted it. What I need to know is how can I get the log details of the CMS errors or CMS changes. For any changes in page or blocks we can use ChangeLog in Admin mode. But for my project I need to record the Episerver CMS login details , admin mode errors if any(like accidental change of some values which cause the project to load) . I want these details to be recorded into a text file. Please suggest any method if you know. 

Thanks in advance.
