Too check the health of the databases run a DBCC CHECKDB command every day.
For the instances there's not much to do but monitoring the resources usage (CPU, RAM and Storage).

There is sometimes the need to do a quick SQL Server healthcheck. Usually this is needed before a maintenance or a migration takes place or after a problem has been resolved. The time given to you for this typical healthcheck is usually short, so let’s see how you can do this in a quick and efficient manner:



The Eventviewer tool is the first place you should look for Operating System level issues. Don’t waste too much time on the Application log, as the SQL Server messages you will find there, are duplicates of the messages you will also see at the SQL Server ERRORLOG. The System log is where you should put the focus on. I usually filter the log so that it shows only the Errors and Warnings – Information messages are useful for troubleshooting specialized issues and not for generic healthchecks. Error and Warning event sources that usually draw my attention are:


(possible NTFS corruption messages)


(possible Storage issues)


(Unexpected shutdowns)


(Unexpected shutdowns)


(Unexpected shutdowns)



These error log files are usually found here:

C:\Program Files\Microsoft SQL Server\<instance_name>\MSSQL\Log

They can be accessed from inside SQL Server Management Studio if you prefer so.

Messages that usually draw my attention are:

  All kinds of Errors (except login errors, which are usually spammed in the ERRORLOG)

  Any enabled trace flags (you will see them appear in this format: -TXXXX, where XXXX is a number)

  Any database corruption messages

Also these messages:

  A significant part of sql server memory has been paged out

(incorrect memory configuration)

  SQL Server has encountered x occurrence(s) of I/O requests taking longer than 15 seconds to complete on file

(storage performance issues)

  SQL Server is starting at high priority base

(priority needs to be changed back to normal)

  Deadlock encountered …. Printing deadlock information






You can use these steps to quickly check if your SQL Server has any performance issues:



The above checks should not take more than 30-40 minutes to complete.

This is quite a large topic. You have to monitor lots of performance counters, as well as other information like wait and file stats from inside SQL to really get a good server "health check".

If by a health check, you mean checking the consistency of the database. Then you would need to run a DBCC CHECKDB against the database. This would definitely affect performance if the database is a highly transactional database due to kind of locks the consistency check needs to acquire while performing the operation and also the IO done on the database would increase.

Normally when I perform a health check I usually do a number of things. You can get a good start by running the SQL Server Best Practice Analyzer : against your servers.

In case you want to check the performance metrics for the database. Eg. The most expensive queries executed against the database w.r.t. to I/O or CPU or Duration. Then you could use Performance Dashboard.

Recently we ran in to an issue while running some SQL jobs where we were trying to process the cubes.  We got an error saying failure stating 'NT SERVICE\SQLSERVERAGENT does not have access to Analysis Services. So this is a way to automate that wit…
It is possible to export the data of a SQL Table in SSMS and generate INSERT statements. It's neatly tucked away in the generate scripts option of a database.
Using examples as well as descriptions, and references to Books Online, show the documentation available for datatypes, explain the available data types and show how data can be passed into and out of variables.
Viewers will learn how to use the INSERT statement to insert data into their tables. It will also introduce the NULL statement, to show them what happens when no value is giving for any given column.
