Graphite output send different metrics the same names

[AlexAkulov]

I try telegraf on Windows and use grapite as an output plugin.
I can see how telegraf is sending metrics about 2 disks (C: and D:)

> diskio,host=K1411013,name=C:,serial=unknown io_time=0i,read_bytes=0i,read_time=0i,reads=0i,write_bytes=0i,write_time=0i,writes=0i 1453925823165540900
> diskio,host=K1411013,name=D:,serial=unknown io_time=0i,read_bytes=0i,read_time=0i,reads=0i,write_bytes=0i,write_time=0i,writes=0i 1453925823166041000

But finally 2 metrics with the same name come to graphite
