Hi all,
We use log4j2, version 2.11.1, and have programmatic configuration because
we don't know until runtime what the logging settings are. For instance,
log directory for file logging, or syslog settings if that's used instead.
I can provide the code we use to set things up if it helps, but don't know
if that's needed given description/exceptions below. Our problem is that
the Configurator.initialize(builder.build()) step doesn't throw exceptions
back to us. Our builder is:
ConfigurationBuilder<BuiltConfiguration> builder =
ConfigurationBuilderFactory.newConfigurationBuilder()
Instead, it outputs stack traces to std err (or out), so we have large
stack traces at startup instead of a message what we would provide to the
end user. Worse, no exception is thrown back to our code, so we start up
anyway, except with no logging any more once we get to the point that std
out/err are supposed to go to our logs.
The culprit is PluginBuilder#build, around line 128:
} catch (final Exception e) {
LOGGER.error("Could not create plugin of type {} for element
{}: {}",
this.clazz, node.getName(),
(e instanceof InvocationTargetException ?
((InvocationTargetException) e).getCause() : e).toString(), e);
}
The stacks output are below. Is there anything I can change to not have
log4j2 print stack traces, and more importantly find out that something
went wrong so we know to not keep running?
Thanks,
Bobby
Output at startup for a simple case like the log directory (for file
logging) not being writeable:
