Monitoring MSSQL server 2005 from Linux

Hi,

I was wondering whether any of you is monitoring MSSQL server 2005
(whatever information could be obtained) from a remote Linux server with
the use of SNMP or WMI-perl scripts (for example via MRTG or Cacti)?
Is something like that even do-able with MSSQL 2005? Could you share
some information on your monitoring solution?

Thanks,
Aleu
