I've read guides where its recommended to change the default value of how big the interval is (in seconds) from 1 second to 1 minute, up to around 10 minutes per 'scan'.Also for a list of all specific counters for SQL2005 use the Dynamic Management View: sys.dm_os_performance_countersThis will however use counters for each DB on the server in question (so you could end up with quite a few!)Thu, 11 Dec 2008 08:43:07 GMTDanb7183http://www.sqlservercentral.com/Forums/Topic457167-149-1.aspxJust be sure that you're capturing them to a file and not using the GUI. If this causes your server to go down, you were already in severe trouble and you need this information.Mon, 28 Jul 2008 06:26:32 GMTGrant Fritcheyhttp://www.sqlservercentral.com/Forums/Topic457167-149-1.aspxIT depends on the number and type of counters used but in my eperience I've never seen more thant a 1% or 2% increase in CPU.Mon, 28 Jul 2008 06:24:09 GMTScalability Doughttp://www.sqlservercentral.com/Forums/Topic457167-149-1.aspxHi, We have started monitoring our server's performance using PERFMON counter data.We have a doubt is by running this tool on the server(DB/APP server) of a site ,would result in any performance issues for the site/server?Can anyone confirm us on the issues if any in just enabling the counters?Mon, 28 Jul 2008 00:46:59 GMTswineethamurthyhttp://www.sqlservercentral.com/Forums/Topic457167-149-1.aspxThis is a great help and a perfect start, thanks so much for your help :)KelleyWed, 20 Feb 2008 09:01:21 GMTkelleysimmonshttp://www.sqlservercentral.com/Forums/Topic457167-149-1.aspxKelly, some key counters and their significance...processor queue length ( < 2 / processor )disk queue length (<1000/spindle)%disk time (obviously <100, the lower the better)contect switches/sec (the lower the better)Hope this helps,DougTue, 19 Feb 2008 07:43:09 GMTScalability Doughttp://www.sqlservercentral.com/Forums/Topic457167-149-1.aspxI've got a core, basic, set of counters that I suggest using [url=http://www.simple-talk.com/sql/performance/sql-server-performance-crib-sheet/#seventh]here[/url].

My question is what are the top key perfmon objects and counters I should be capturing? I am using this performance data for both under-utilized and over-utilized servers for consolidation/virtualization and on the other end of the scope pro-active fixes in our environments so I will also need to get the proper thresholds that would fall in the under-utilized vs. over-utilized spaces. oh yeah, in between I also have a slot I call optimum performance :) any help would be greatly appreciated.KelleyMon, 18 Feb 2008 20:05:53 GMTkelleysimmons
