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(), "\n";

           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.
