NAME

       Log::Log4perl::Appender::ScreenColoredLevel - Colorize messages according to level

SYNOPSIS

	   use Log::Log4perl qw(:easy);

	   Log::Log4perl->init( <<'EOT');
	     log4perl.category = DEBUG, Screen
	     log4perl.appender.Screen = 
		 Log::Log4perl::Appender::ScreenColoredLevels
	     log4perl.appender.Screen.layout = 
		 Log::Log4perl::Layout::PatternLayout
	     log4perl.appender.Screen.layout.ConversionPattern = 
		 %d %F{1} %L> %m %n
	   EOT

	     # Appears black
	   DEBUG "Debug Message";

	     # Appears green
	   INFO  "Info Message";

	     # Appears blue
	   WARN  "Warn Message";

	     # Appears magenta
	   ERROR "Error Message";

	     # Appears red
	   FATAL "Fatal Message";

DESCRIPTION

       This appender acts like Log::Log4perl::Appender::Screen, except that it colorizes its output, based on the priority of the message sent.

       You can configure the colors and attributes used for the different levels, by specifying them in your configuration:

	   log4perl.appender.Screen.color.TRACE=cyan
	   log4perl.appender.Screen.color.DEBUG=bold blue

       You can also specify nothing, to indicate that level should not have coloring applied, which means the text will be whatever the default
       color for your terminal is.  This is the default for debug messages.

	   log4perl.appender.Screen.color.DEBUG=

       You can use any attribute supported by Term::ANSIColor as a configuration option.

	   log4perl.appender.Screen.color.FATAL=
	       bold underline blink red on_white

       The commonly used colors and attributes are:

       attributes
	   BOLD, DARK, UNDERLINE, UNDERSCORE, BLINK

       colors
	   BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE

       background colors
	   ON_BLACK, ON_RED, ON_GREEN, ON_YELLOW, ON_BLUE, ON_MAGENTA, ON_CYAN, ON_WHITE

       See Term::ANSIColor for a complete list, and information on which are supported by various common terminal emulators.

       The default values for these options are:

       Trace
	   Yellow

       Debug
	   None (whatever the terminal default is)

       Info
	   Green

       Warn
	   Blue

       Error
	   Magenta

       Fatal
	   Red

       The constructor "new()" takes an optional parameter "stderr", if set to a true value, the appender will log to STDERR. If "stderr" is set
       to a false value, it will log to STDOUT. The default setting for "stderr" is 1, so messages will be logged to STDERR by default.  The
       constructor can also take an optional parameter "color", whose value is a  hashref of color configuration options, any levels that are not
       included in the hashref will be set to their default values.

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.
