Re: [DISCUSS] Improve colored logging output

[Guillaume Nodet]

I modified it a bit to use the red / yellow / green for error / warn / info
levels but kept cyan for debug / trace:

10:03:51.308 DEBUG [FelixStartLevel] ServiceEvent REGISTERED -

I've pushed a branch [1] if people want to have a look.  The properties for
colors have been extracted out of the pattern for ease of configuration,
but unfortunately they are duplicated because the "log:command" and
"bin/karaf run" use different mechanism.

I plan to have a look at removing some useless thread informations, i.e.
giving some names to threadpools when possible.

Sorry, not Logstash: Logback.

Re: [DISCUSS] Improve colored logging output

I really like the colour scheme that Spring Boot uses by default with
Logstash and Log4j2 and is what I tend to copy/paste into my own logging
config files.

[DISCUSS] Improve colored logging output

[Guillaume Nodet]

I'm wondering about improving the colored logging output in both the
"log:display" command and when running "bin/karaf run".
I'm thinking about keeping the log file the way it is, but simplifying the
output on the console and improving the color a bit.

23:11:44.198 *INFO* [pool-14-thread-3] Registering commands for bundle
org.apache.karaf.log.core/4.2.0.SNAPSHOT

23:11:51.043 *ERROR* [Karaf local console user karaf] Exception caught
while executing command

...

23:15:19.481 *DEBUG* [Karaf local console user karaf] Executing command:
'ld'

I've currently reused the maven color scheme, so *debug* *info* *warning*
*error*.

The current behavior is that "bin/karaf run" is uncolored, while
"log:display" have fully colored lines, both having the same output as the
log file.  The problem with the log file pattern is that it oftens does not
fit in the screen, even with a large one.

If you have any thoughts, let me know...
I have the above code ready to commit, but I'm happy to change the scheme,
drop it, or whatever else...

Cheers,
Guillaume
