Subject [jira] [Commented] (LOG4J2-913) Allow to load log4j2 configuration from a centralized repository, like a database or a webservice
Date Fri, 27 Nov 2015 08:41:10 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15029622#comment-15029622

Ralph Goers commented on LOG4J2-913:

Configurator already supports using a URL. However, look at the code in the issue description.
He is also looking for updating the configuration. I would assume that would require polling
the resource and passing an if-modified-since header and not reconfiguring if a 304 is returned.

> Hi.
> I've worked in some projects that require having a single configuration point for all
my loggers since basically, all of them are web applications. Since controlling the logging
event flood can be problematic when the applications are in production, it would be great
if, along with the current XMLConfiguration and JSONConfiguration, there would be a configuration
mechanism that could load the log4j2 from a remote location, whether it's a webservice (SOAP,
ReST) or a database.
> The contract can be summarized like this:
> * Set a configuration endpoint
> * Set a polling interval
> * Allow authentication
> * Load a given named configuration
> * Reconfigure if required.
> Right now, I'm been scratching this need by code, using a ScheduledExecutorService and
a pice of code like this:
> {code:java}
>         LoggerContext ctx = null;
>         URI uri = null;
>         try {
>             uri = new URI("http://localhost:7001/log4j2config/getlog4j2xmlconfig?appCode=log4jConfig&section=full");
>         } catch (URISyntaxException e) {
>             System.err.println(e.getMessage());
>         }
>         ctx = Configurator.initialize("Log4J2Conf", Thread.currentThread().getContextClassLoader(),
>         ctx.start();
> {code}
> However, I believe that since this is a common scenario, it could be implemented as a
new plugin.
> Thank you very much.
