Segment Usage/Freespace by device.

Question

I need the ability to monitor my segment usage by device in MB for data growth.  The scripts I have found/developed are not providing the information I need.   At a minim the devices are separated by data and index.  Would any one have a good script for this?
Example.
Database ScoobyDoo.
database_name database_size
ScoobyDoo 284536.0 MB  
reserved           data                 index_size    unused    
164417808 KB 92098352 KB   70607632 KB 1709536 KB
Segment            Device                                   PhyDvSize   AssignedDvSize        DataUsed    %Avail
Seg_SD_Data    ScoobyDoo _Data1                 81920          81000                       79,999          0%
Seg_SD_Data    ScoobyDoo _Data2                 81920          81000                       54,399          33%
Seg_SD_IDX1    ScoobyDoo _IDX_Shaggy        30000          29500                       12,853          57%
Seg_SD_IDX2    ScoobyDoo _IDX_Velma          30000          29200                       15,478          48%

Answer 1

Here is the code:
Select 'Segment Usage'
  select db_name(d.dbid) as db_name, v.name,
   "Data Size," = sum(size * abs(sign(segmap - 4))) *16/1024,
   "Data Used," = sum((size - curunreservedpgs(d.dbid, lstart, unreservedpgs)) * abs(sign(segmap - 4)))*16/1024 ,
  convert(varchar(10),100-ceiling(100 * (1 - 1.0 * sum(case when u.segmap != 4 then curunreservedpgs(u.dbid, u.lstart, u.unreservedpgs) end) / sum(case when u.segmap != 4 then u.size end)))) as '% data spacee avail'
  from master..sysdatabases d, master..sysusages u,
       master..sysdevices v
  where u.dbid = d.dbid  and d.status != 256 and
  db_name(d.dbid) not like '%model%' and
  db_name(d.dbid) not like 'temp%' and
  db_name(d.dbid) not like 'sybsystem%' and
  upper(v.name) not like 'TAPEDUMP%' and
  upper(v.name) not like '%LOG%' and
  v.vdevno = u.vdevno
group by d.dbid, v.name
order by d.dbid, v.name
