Simplest way to programmatically write debug line to Episerver log

Hey Guys,

i'm using this:

private static readonly ILogger Logger = LogManager.GetLogger();
Logger.Debug(string.Format("CacheManager - TEST"));

But it is not written in the EPiServer log located in the app_data folder...

Is this not the correct way to do this?

Can you set a breakpoint on Logger.Debug(...) and check if Logger.IsDebugEnabled returns true?

How does your EPiServerLog.config file look like?

On line 10, you have threshold value="Error" which means that Info, and Debug messages won't be logged.

Is that a comma seperated field... If i want the debug messages to be logged as well do i write threshold value="Error,Debug" ?

No, single value.

thanks good info...

there you say that "If we open EPiServerLog.config file, we'll see that threshold value is set to Error. This means that only Error (and higher level) messages will be logged."

What is the level structure. So if i add Debug, will Error also be logged?

What is the correct level sequence. Because if i add Debug, i want Error also to be logged..

DEBUG
INFO
WARN
ERROR
FATAL

If set DEBUG or ALL, everything will be logged.

If you set ERROR, only ERROR and FATAL will be logged.
