Hi,
First of all, thanks a lot for this great module!
I'm working on a project with libraries accessible via both a web
front-end (HTML::Mason, mod_perl) and command line scripts.
Most of the logging is intended for Syslog, but in some cases I
temporarily use the Screen appender (command-line) and the String
appender for output to the web.
My initial config looks like:
log4perl.oneMessagePerAppender = 1
log4perl.category.Netdot = ERROR, Syslog
log4perl.category.Netdot::Model = INFO, Syslog
log4perl.category.Netdot::Model::Device = INFO, Syslog
log4perl.category.Netdot::UI = INFO, Syslog
log4perl.appender.Syslog = Log::Dispatch::Syslog
log4perl.appender.Syslog.ident = netdot
log4perl.appender.Syslog.facility = local0
log4perl.appender.Syslog.min_level = debug
log4perl.appender.Syslog.layout =
Log::Log4perl::Layout::SimpleLayout
and then I add appenders as needed, via the API:
In a Mason component:
$logger = Log::Log4perl->get_logger('Netdot::Model::Device');
# Notice that I intentionally undef the object in order to call
DESTROY and make sure the string
# is not being used (wasting memory) except when this component is
called
if ( $logstr = Log::Log4perl::appender_by_name('updatedevice.html') ){
undef($logstr);
}
$logstr =
Log::Log4perl::Appender->new(Log::Log4perl::Appender::String,
name=>'updatedevice.html')
$logger->add_appender($logstr);
... (stuff that produces log output)
# somewhere in the presentation code:
print $logstr->string();
# at the end:
undef($logstr) if defined $logstr;
The problem is my results are intermittent. Sometimes I see the output
in the web page, sometimes I don't. I'm not sure what I'm doing wrong
here. Any ideas? Suggestions on how to do this some other way?
Thanks in advance.
