Expected behavior:

I don't get the temp_c value.

root# telegraf -config /etc/telegraf/telegraf.conf -test|grep smart_device
> smart_device,dc=de-home-serverx-1,device=sda,enabled=Enabled,host=serverx,model=SanDisk\ Ultra\ II\ 240GB,serial_no=XXXXXXX,wwn=XXXXXXXX exit_status=0i,health_ok=true 1537184553000000000

Actual behavior:

I think the brackets behind the raw value of 194 cause problems when parsing.

194 Temperature_Celsius     -O---K   066   065   ---    -    34 (Min/Max 19/65)

On another system I also have the value with brackets but without a "/". But parsing works there.

194 Temperature_Celsius -O---K 044 063 000 - 44 (0 21 0 0 0)

I'm using Telegraf 1.9.0 on Ubuntu 16.04 smartools 6.5 2016-01-24 and I'm having the same issue.
