Hi

i have a requirement wherein on host metric i want ,  
mount point , total, used\_bytes, used\_pct in tsvb but it is not showing in table timeseries option

I did a workaround by having multiple max of metric total, used\_bytes, used\_pct . by mount point.  
problem it is shows in full bytes is there option to convert it to gb/ mb ?

Q2 . if i use timelion in dashboard will it retrieve results according to global filters , time filters ?
