I am using the new OSGi LogService 1.4.
I’ve extended my small sample app. https://github.com/phhoef/osgi-test
The problem is basically the same. The log can be written by some packages, but 
my packages are not.
When the app is running, you can fire a request against my small rest service: 
http://localhost:9090/serverInfo?repoName=system1
The log is written on line 55 of the ServerInfoControllerImpl.java in the

I am also getting confused by the names. You’re saying it’s Felix logback. But

slf4j is just a compile dependency. It's the API "used" by logback.

What logging API does it use?

That project is no longer valid. It was the basis of the contribution to
Apache Felix. You should ignore it.

When using Felix Logback, I would start by having NO configurations for
logging besides the logback.xml.

I wonder if it would be possible to share something like a git(hub) project
with me?

Re: How to configure LogService

[Philipp Höfler]

Hallo,

@Raymond Auge<mailto:raymond.a...@liferay.com>
I am using the new OSGi LogService 1.4.
I’ve extended my small sample app. https://github.com/phhoef/osgi-test
The problem is basically the same. The log can be written by some packages, but 
my packages are not.
When the app is running, you can fire a request against my small rest service: 
http://localhost:9090/serverInfo?repoName=system1
The log is written on line 55 of the ServerInfoControllerImpl.java in the 
rest-service bundle.

I am also getting confused by the names. You’re saying it’s Felix logback. But 
on the logback website Felix or Apache is never mentioned. Maybe I am just 
using the wrong dependencies?

@Alain Picard<mailto:pic...@castortech.com>
Thanks for the overview. Unfortunately, the picture was removed.
I am the only one having this problem? Would you mind uploading the picture and 
sending the link?.

Thanks for your help,
Philipp

slf4j is just a compile dependency. It's the API "used" by logback.

When using Felix Logback, I would start by having NO configurations for
logging besides the logback.xml.

I wonder if it would be possible to share something like a git(hub) project

slf4j is just a compile dependency. It's the API "used" by logback.

Re: How to configure LogService

[Philipp Höfler]

Hallo Ray,

thanks for your explanation.

Based on the new information, I am trying to use Logback.
I actually made some progress, but still have one fundamental problem.

I added the logback maven dependencies. I found some documentation from you, 
saying that I also have to add sl4j as dependency.
Why is this necessary?

I set the configurationFile as runproperties and of course I added the 
configuration file itself:




myApp.log
true
true


%-4relative [%thread] %-5level %logger{35} - 
%msg%n

















Here is where the problem starts.
I do not get any log entry for any of the three configured packages, especially 
of "com.pernexas".
BUT, when I set the root level to DEBUG I do get log entries from several 
bundles (e.g. jetty). Unfortunately, I do not get any log from com.pernexas.

I found also your Github project "osgi-to-logback". I am not sure, if this is 
still necessary now, after the release of osgi r7 and new logback? Especially 
as the project is archived.

Is it still necessary to add a configuration for a bundle in order to configure 
the log level through config admin? I was hoping, that this is now done by 
logback?

Thanks for your patient help.
Philipp

How to configure LogService

[Philipp Höfler]

Hi,

with the latest update of the Felix SCR, I am able to get an instance of the 
LogService by referencing the LoggerFactory using this line of code:
@Reference(service = LoggerFactory.class)
private Logger _logger;

Now, I would have expected, that I can configure the LogService through the Web 
Console (Configuration Admin).
There is a menu LogService in the WebConsole and it says “Log Service is 
running”, but there is not one single log entry available nor can I change the 
log level of classes (or bundles).

I found the documentation 
(http://felix.apache.org/documentation/subprojects/apache-felix-log.html) and 
it says that it is possible to configure the logging through the Configuration 
Admin.
But it’s not clear to me, what exactly I have to do.
Is it necessary to use LogBack (or any other logging framework)? According to 
my current understanding, I do not have to use an additional logging framework. 
Anyhow, do you recommend utilizing one?

Obviously, I am missing something important.
Could somebody please give me an introduction on how to properly use the 
LogService. I think I make correctly use of it in the code, but I do not 
understand how to use/configure it after compilation.

Thanks,
Philipp
