How to differentiate process instances in perfmon

In a multi-instance cluster, how can you match a named sql server instance
with an instance of sqlservr.exe? When setting up counter collection in
perfmon, I choose the "process" performance object, then the "% processor
time" counter". In list of instances, I can see sqlservr#1, sqlservr#2, etc.
How do I know which named instance each of those represents?
TIA.
Hello
One way (I dont know if is the best way) is to match the ProcessID on
Process Counter from Performance Monitor to the ProcessID that is on the
ErrorLog from the Instance.
Something like:
PerfMon -> Process -> ProcessID -> Select SQLServer# on the instances.
Now go to SQL Server Enterprise Manager for each instance and look on the
ErrorLog for the line:
Server Process ID is 3636.
That should be easy if you need to do just on time.

|||That's a good idea, thanks for the suggestion.
I don't have access to the error log on all the servers, but I can use
SELECT SERVERPROPERTY ('processid')

How to determine programatically what datafiles are associated with a database

I'm writing a data collection script to gather database and data file
information. This information will be used for reporting and analysis. I
want to be able to tell what data files are associated with each of the
databases. sysfiles doesn't include the database name and sysaltfiles
doesn't include all of the datafiles.
Query I'm using:
use master
select f.file_name, f.name, ...
from master.dbo.sysaltfiles a ,
dbo.sysfiles f ,
master.dbo.sysdatabases db
where a.name=f.name
and a.fileid = f.fileid
and a.dbid = db.dbid
and db.name = 'master'
I can probably infer the database name from the name column but I'd rather
not go there!
Please don't tell me to go somewhere and point and click. I'm monitoring
almost 70 databases and this data needs to be collected on a daily basis.

Message posted via http://www.webservertalk.com|||I figured out what the procedure does.
Perhaps I'm not clear I want the database name and all associated data file
names. The following query gives me table names.
select so.name as Table_Name,
sfg.groupname as GroupName,
sf.name as LogicalName,
sf.filename as PhysicalFileName
from dbo.sysobjects so
inner join sysindexes si
on so.id = si.id

group by so.name,
sfg.groupname,
sf.name,
sf.filename

include it in future versions of sql server. however, it is widely used. you
can check the definition (in master db) with:
exec sp_helptext 'sp_msforeachdb'
nothing fancy (builds a cursor internallly), but very handy.

The database may have two or more log files. You also need to see them
Look at this script helps you.
SELECT RTRIM(filename)
FROM sysfiles
WHERE fileid = (SELECT MIN(fileid) FROM sysfiles)
UNION ALL
SELECT RTRIM(filename)
FROM sysfiles
WHERE fileid > (SELECT MIN(fileid) FROM sysfiles) AND
fileid < (SELECT MAX(fileid) FROM sysfiles)
UNION ALL
SELECT RTRIM(filename) FROM sysfiles
WHERE fileid = (SELECT MAX(fileid) FROM sysfiles)
