George and I were thinking of adding a bunch of new checks/reports to SQLCop. SQLCop detects the following issues right now.

Code

Column

Table/Views

Indexes

Configuration

  • Database Collation
  • Auto Close
  • Auto Create
  • Auto Shrink
  • Auto Update
  • Compatibility Level
  • Login Language
  • Old Backups
  • Orphaned Users
  • User Aliases
  • Ad Hoc Distributed Queries
  • CLR
  • Database and log files on the same physical disk
  • Database Mail
  • Deprecated Features
  • Instant File Initialization
  • Max Degree of Parallelism
  • OLE Automation Procedures
  • Service Account
  • SMO and DMO
  • SQL Server Agent Service
  • xp cmdshell

Health

  • Buffer cache hit ratio
  • Page life expectancy

I was thinking about adding an informational section to SQLCop and also some additional checks. Leave me a comment if you have other ideas or agree with the ones presented here

Would you like to know the last time DBCC ran successfully against your database?

This code would report that

CREATE TABLE #Test(ParentObject VARCHAR(500),Object VARCHAR(500),Field  VARCHAR(500),VALUE VARCHAR(500))

DECLARE @db VARCHAR(500)
SELECT @db =  db_name()

INSERT #Test
EXEC('DBCC DBINFO (''' + @db + ''') WITH TABLERESULTS')

SELECT DISTINCT Value FROM #Test
WHERE field = 'dbi_dbccLastKnownGood'

DROP TABLE #Test

If we add the configuration section would it be beneficial if we added the min and max values for the following

max worker threads

max text repl size (B)

max degree of parallelism

max server memory (MB)

max full-text crawl range

min memory per query (KB)

min server memory (MB)

For example

SELECT * FROM sys.configurations
WHERE name like( 'max%')

SELECT * FROM sys.configurations
WHERE name like( 'min%')

What about fillfactor?

SELECT * FROM sys.configurations
WHERE name  = 'fill factor (%)'

How about the 50 most used stored procedures

SELECT top 50 * FROM(SELECT COALESCE(OBJECT_NAME(s2.objectid),'Ad-Hoc') AS ProcName,execution_count,s2.objectid,
    (SELECT TOP 1 SUBSTRING(s2.TEXT,statement_start_offset / 2+1 ,
      ( (CASE WHEN statement_end_offset = -1
         THEN (LEN(CONVERT(NVARCHAR(MAX),s2.TEXT)) * 2)
         ELSE statement_end_offset END)  - statement_start_offset) / 2+1)) AS sql_statement,
       last_execution_time
FROM sys.dm_exec_query_stats AS s1
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 ) x
WHERE sql_statement NOT like 'SELECT * FROM(SELECT coalesce(object_name(s2.objectid)%'
and OBJECTPROPERTYEX(x.objectid,'IsProcedure') = 1
and exists (Select 1 from sys.procedures s
where s.is_ms_shipped = 0
and s.name = x.ProcName )
ORDER BY execution_count DESC

How about stored procedures with the highest average CPU time

SELECT top 50 * FROM(SELECT COALESCE(OBJECT_NAME(s2.objectid),'Ad-Hoc') AS ProcName,execution_count,s2.objectid,
    (SELECT TOP 1 SUBSTRING(s2.TEXT,statement_start_offset / 2+1 ,
      ( (CASE WHEN statement_end_offset = -1
         THEN (LEN(CONVERT(NVARCHAR(MAX),s2.TEXT)) * 2)
         ELSE statement_end_offset END)  - statement_start_offset) / 2+1)) AS sql_statement,
       s1.total_worker_time/s1.execution_count as AverageCPUTime
FROM sys.dm_exec_query_stats AS s1
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 ) x
WHERE sql_statement NOT like 'SELECT * FROM(SELECT coalesce(object_name(s2.objectid)%'
and OBJECTPROPERTYEX(x.objectid,'IsProcedure') = 1
and exists (Select 1 from sys.procedures s
where s.is_ms_shipped = 0
and s.name = x.ProcName )
ORDER BY AverageCPUTime DESC

Do you want to see all the different programs connected to your server?

SELECT COUNT(*) Count,program_name 
FROM sys.sysprocesses
WHERE status <> 'background'
GROUP BY program_name
ORDER BY 1 desc

This returns something like this on one of my boxes

Do you want to know the file size, space used and free space for all of the files for your database?

select
    CONVERT(DATE,GETDATE()) AS [Date],
    a.FILEID,
    [FILE_SIZE_MB] =
        convert(decimal(12,2),round(a.size/128.000,2)),
    [SPACE_USED_MB] =
        convert(decimal(12,2),round(fileproperty(a.name,'SpaceUsed')/128.000,2)),
    [FREE_SPACE_MB] =
        convert(decimal(12,2),round((a.size-fileproperty(a.name,'SpaceUsed'))/128.000,2)) ,
    NAME = left(a.NAME,35),
    FILENAME = left(a.FILENAME,60)
from
    dbo.sysfiles a

Here is what the output would look like
