trends, alerting and solution help

Posted: 23 Apr 2013 01:49 AM PDT

hopefully i will be able to get across what it is i am trying to achieve and someone can then point me in the right direction.i have developed a database and SSIS package which is used to process and store monitoring information about a data centre. one of the items monitored is disc space. what i now need to do is trend out the disc usage so that then i can predict when certain disc usage threshold will be met. the place i am stuck is how to deliver this/report this to the team who requires this information. Any help on possible solutions would be grand. I'm not expecting someone to do the work for me as i am proficient in most of the SQL Server stack. its just this has me stumped because i have never worked with trends before.ThanksTUpdate i have tried excel 2013 using poverpivot and the trends do not appear to be persistent within the charts and when displayed its hard to work out the date the threshold is reached..

SQL 2012 editions Question

Posted: 22 Apr 2013 11:52 AM PDT

HiWe are looking at moving to SQL2012 from 2008 standard edition. We are weighing up whether to go for the standard or BI editions, The only thing that really impacts on the decision is the use of Power pivot and publishing the spread sheets into SharePoint. Does the Standard version of SQL 2012 allow us to do this?ThanksNigel

PWAIT_MD_RELATION_CACHE and MD_LAZYCACHE_RWLOCK wait types

Posted: 22 Apr 2013 04:03 AM PDT

I'm hoping someone can give me some more information on either of these two wait types PWAIT_MD_RELATION_CACHE and MD_LAZYCACHE_RWLOCK. We started seeing these happen on queries that were accessing a table with 1,000 records, most of the waits were over a couple minutes. No blocking was occurring at the time, and other queries against the database were able to complete successfully. From doing a bit of research I was able to find this description on MSDN for PWAIT_MD_RELATION_CACHE: "Occurs during internal synchronization in metadata on table or index." This made me believe the issues was revolving around a large insert, update or delete that was occurring during that time, or manipulation of an index on the table. No records had been inserted or updated in the last 3 days, the indices were last rebuild 2 days prior to the issue. I've been unable to find anything in relation to MD_LAZYCACHE_RWLOCK.We are currently running Microsoft SQL Server 11.0.2100.60.Any help or ideas would be appreciated.
