Hi everyone,

 

As I have mentioned in a previous post, I have been trying to learn how to use Boost.Log.

 

I have been experimenting with logging to a file with filtering and specifying the log formatting in three different ways, namely:

 

1. Specifying the log formatting using a lambda type expression.

2. Specifying the log formatting using a plain text string with placeholders for the attributes that I have defined.

3. Specifying the log formatting in a settings file.  (However, the formatting string is exactly the same as in 2 above.)

 

I have attached a copy of my source code and settings file.  Note that I comment out parts of the source code file depending on which option I use above.

 

The problem I’m encountering is when I use options 2 & 3 above, the severity level string does not appear in the log.

But if I use option 1, the severity level string appears as expected.  It is my understanding that severity level is a pre-defined attribute when using a severity_logger.

 

Am I missing something when using options 2 & 3?

 

If I decide to use my own severity level enumeration, what do I need to do?

Kind regards,
Leo
