Description

As I was using SolrGangliaReporter, default metrics names will contains "/", which is
offen used in FileSystem as an seperator, than it encounters ERROR cause creating
metrics data file failed, bellow is the Exception in /var/log/messages:

I think the metrics name should be normalized for different reporter，such as SolrGangliaReport.
Some times other normalization is used for other reason，but now，for ganglia，It must
replace the "/" .
