Log view for netbeans - lumbermill, chainsaw ...

Hi,

in my nb platform apps I use the log window to analyse logging of complex 
processing jobs. The output is also written into xml files. All is done by 
log4j.

There is a great apache tool to analyse these logfiles:

http://logging.apache.org/chainsaw

And I also found a blog article from Geertjan about a nb plugin for viewing 
logfiles

https://blogs.oracle.com/geertjan/lumbermill:-log4j-messaging-in-netbeans-ide

It seems that the module is no longer available:

https://netbeans.org/community/news/show/646.html

Thatś why I am now thinking about to implement a new logging view module with 
the following features:

- gui as visual view for log files (file type recognition)
- alternative GUI to the log output window to analyse the normal nebeans log 
output in any platform app

Andy ideas about this?

Is the alow module lumbermill somewhere available? Is is useful to look in 
this or do you think it is better suddenly to start from the apache chainsaw 
code?

Does anybody else has implemented similar things and can give hints or can 
share code?

best regards
Oliver
