Log::Log4perl::Appender::RRDs is a 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; }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:outTo read out the round robin database later on, use rrdtool fetch or rrdtool graph for graphic displays.
