NAME

       Log::Log4perl::Appender::TestBuffer - Appender class for testing

SYNOPSIS

	 use Log::Log4perl::Appender::TestBuffer;

	 my $appender = Log::Log4perl::Appender::TestBuffer->new(
	     name      => 'mybuffer',
	 );

	     # Append to the buffer
	 $appender->log(
	     level =  > 'alert',
	     message => "I'm searching the city for sci-fi wasabi
"
	 );

	     # Retrieve the result
	 my $result = $appender->buffer();

	     # Clear the buffer to the empty string
	 $appender->clear();

DESCRIPTION

       This class is used for internal testing of "Log::Log4perl". It is a "Log::Dispatch"-style appender, which writes to a buffer in memory,
       from where actual results can be easily retrieved later to compare with expeced results.

       Every buffer created is stored in an internal global array, and can later be referenced by name:

	   my $app = Log::Log4perl::Appender::TestBuffer->by_name("mybuffer");

       retrieves the appender object of a previously created buffer "mybuffer".  To reset this global array and have it forget all of the
       previously created testbuffer appenders (external references to those appenders nonwithstanding), use

	   Log::Log4perl::Appender::TestBuffer->reset();

NAME

       Log::Log4perl::Appender::RRDs - Log to a RRDtool Archive

SYNOPSIS

	   use Log::Log4perl qw(get_logger);
	   use RRDs;

	   my $DB = "myrrddb.dat";

	   RRDs::create(
	     $DB, "--step=1",
	     "DS:myvalue:GAUGE:2:U:U",
	     "RRA:MAX:0.5:1:120");

	   print time(), "
";

	   Log::Log4perl->init(qq{
	     log4perl.category = INFO, RRDapp
	     log4perl.appender.RRDapp = Log::Log4perl::Appender::RRDs
	     log4perl.appender.RRDapp.dbname = $DB
	     log4perl.appender.RRDapp.layout = Log::Log4perl::Layout::PatternLayout
	     log4perl.appender.RRDapp.layout.ConversionPattern = N:%m
	   });

	   my $logger = get_logger();

	   for(10, 15, 20, 25) {
	       $logger->info($_);
	       sleep 1;
	   }

DESCRIPTION

       "Log::Log4perl::Appender::RRDs" appenders facilitate writing data to RRDtool round-robin archives via Log4perl. For documentation on RRD
       and its Perl interface "RRDs" (which comes with the distribution), check out <http://rrdtool.org>.

       Messages sent to Log4perl's RRDs appender are expected to be numerical values (ints or floats), which then are used to run a "rrdtool
       update" command on an existing round-robin database. The name of this database needs to be set in the appender's "dbname" configuration
       parameter.

       If there's more parameters you wish to pass to the "update" method, use the "rrdupd_params" configuration parameter:

	   log4perl.appender.RRDapp.rrdupd_params = --template=in:out

       To read out the round robin database later on, use "rrdtool fetch" or "rrdtool graph" for graphic displays.
