SQL Server DBA - Send e-mail notification when a database is not online

Checking the databases availability is one of the major task of a DBA which has to be performed  at regular intervals to make sure that the critical live databases are always online and fix them immediately if they are not online. This can be done in "n" number of ways and here is one such method.
The method that i am going to discuss below makes use of "Database Mail" option to send e-mails to the intended recipients when the process finds the status of the database which is not online.

After the "Database Mail" Option is configured all you have to do is to create a job with the below code and schedule it to run every five minutes or every one minute depending on the criticality of the databases that you are going to monitor.

Use this Code if you wish to receive the e-mail in HTML format:

if(select count(*) from sys.databases where state_desc<>'Online')>0

Begin

DECLARE @table  NVARCHAR(MAX) ;

SET @table =

    N'<H1>Offline Databases Report</H1>' +

    N'<table border="1">' +

    N'<tr><th>Database Name</th><th>Database Status</th></tr>' +

    CAST ( ( Select td=name, '',td=state_desc from sys.databases where state_desc<>'Online'

              FOR XML PATH('tr'), TYPE

    ) AS NVARCHAR(MAX) )    +

    N'</table>' ;

EXEC msdb.dbo.sp_send_dbmail @profile_name='ProfileName', --Change to your Profile Name

      @recipients='email@domain.com;email1@domain.com', --Put the email address of those who want to receive the e-mail

    @subject = 'Offline Databases Report',

    @body = @table,

    @body_format = 'HTML' ;

END

Else Print 'All Databases are Online'

 

Use this Code if you wish to receive the e-mail in Plain Text format:

 

if(select count(*) from sys.databases where state_desc<>'Online')>0

Begin

EXEC msdb.dbo.sp_send_dbmail @profile_name='ProfileName', --Change to your Profile Name

      @recipients='email@domain.com;email1@domain.com', --Put the email address of those who want to receive the e-mail

    @subject = 'Offline Databases Report',

    @Query='Select rtrim(ltrim(name)) as DatabaseName,rtrim(ltrim(state_desc)) as CurrentDatabaseStatus from sys.databases where state_desc<>''Online'''

    

END

Else Print 'All Databases are Online'
