Use them as -Dgiraph.metrics.enable=true, after GiraphRunner but before you specify the algorithm of interest. In other words,
hadoop jar .... org.apache.giraph.GiraphRunner \ -Dgiraph.metrics.enable=true \ -Dgiraph.metrics.directory=dir \ org.apache.giraph.examples.SomeAlgorithm \ -ca AlgorithmSpecificOpts -vif InputFormat ... etc. As Matthew mentioned, by default it outputs metrics to the stderr logs---I haven't used the directory option before either.
