In this example, we will create an alert in sql server to be notified when a CPU average workload is 90% within a minute

  • In Object Explorer, expand SQL Server Agent, right-click Alerts, and then click New Alert.
  • In the New Alert dialog box, add a new alert with the properties in the following table.
  • Configure the alert as below :



Name: SQL Performance CPU alert
Type: WMI event Alert
Namespace: \\.\ROOT\CIMV2
Query: SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA “Win32_Processor” AND TargetInstance.LoadPercentage > 90





  • In The Response Panel select the Notify operators check box, and then select the E-mail check box for the Operator_Admin operator
  • On the Options page, select the E-mail check box, in the Additional notification message to send box, type Warning: The Average CPU workload has exceeded 90% on the instance NamedInstance, and then click OK

Index Clean-Up Scripts

dropping un-used ones, adding missing ones, and fine-tuning the ones I already have. I thought I’d share some of the scripts I’ve been using to accomplish this. Un-Used Indexes Script Declare @dbid int     , @dbName varchar(100);   Select @dbid = DB_ID()     , @dbName = DB_Name();   With partitionCTE (object_id, index_id, row_count, partition_count)  As (     Select [object_id]         , index_id         , Sum([rows]) As 'row_count'         , Count(partition_id) As 'partition_count'     From sys.partitions     Group By [object_id]         , index_id )    Select Object_Name(i.[object_id]) as objectName         , i.name         , Case              When i.is_unique = 1          ...

The SQL Server DBA’s Guide to Teradata

By -
Being a long-time devotee of all things Microsoft SQL Server, I had quite a bit of learning to do to get up to speed on our new Teradata appliance. This guide attempts to distill some of what I have learned. I will primarily focus on what I have found most lacking: examples of how to convert SQL Server T-SQL to Teradata SQL. This guide will use the vendor-supplied sample databases:  SQL Server’s AdventureWorksDW2012 , and the  Teradata’s Express 14.0 Retail database . Also, while this is probably self explanatory, the “mufford” object referenced in the Teradata examples is simply my own personal sandbox. You’ll need to replace any “mufford” reference to whatever your development sandbox may be named. Release History: 2012-08-17 – Added UPDATE examples; reformatted 2012-08-12 – Added date examples 2012-08-08 – Initial Release SELECT Statements Simple SELECT SQL Server: Best practice is to qualify the table schema; qualifying the database is optional unless ...
