Information is at the heart of most software systems and the lifeblood of many organizations, so you want the database that stores this information to be efficient and reliable. But as we know, things happen; sometimes bad things. One of the ways that we can prevent bad things from happening is to know about them in advance like the old saying says, "To be forewarned is to be forearmed."
Azure SQL in its many forms has an abundance of features that help you to monitor the state of your databases and database server. Ranging from prebuilt automated monitoring that is augmented with artificial intelligence through to dynamic management views, SQL Server monitors and logs all aspects of the database engine’s operation and configuration. Intelligent Insights and Azure SQL analytics enable you to easily access the wealth of diagnostic and performance data in an easily digestible format.
This course introduces you to the different database monitoring and notification technologies available, how they work, and how to use them. If you have any feedback relating to this course, feel free to contact us at firstname.lastname@example.org.

Now I want to turn my attention on how you might be notified of server-level changes within an SQL Server environment, whether that is on premise or on a VM.
First thing we need to do is set up Database Mail. This can be done through SQL Server Management Studio and Database Mail under the management node. I'll set up a connection to a Gmail account that can be used to send emails, I'll just use the Database Mail configuration wizard to do this.
First, I will set up a profile called Gmail that will use a new Database Mail account. This is all reasonably straightforward, server name is smtp.gmail.com using Port 25, and the server requires a secure connection. The authentication is basic, that is username and password. You'll need to allow less secure apps to access your Gmail account. This is done through the Google security settings.
Now that's done, I'll make my profile public and also make it the default profile. This now set up the trigger that will notify us of the database being created. This involves creating a trigger and server objects within SQL Management Studio.
First off, I will just create the trigger and see what the output looks like. When I create the database we get the SQL that was executed for its creation, specifying the name, files, and respective file sizes. What I'll do now is drop the trigger and recreate it using the sp_send_dbmail procedure to send a notification of the database creation. Recipients can be multiple email addresses separated by semi colons.
You can specify the body of the email to be formatted as HTML, which will allow you to have pretty emails with tables and headings. I've set the importance to high which will mark the email as such. But if the email is for informational purposes, you could use the word normal.
If you wanted to use a Database Mail profile other than the default, that can be specified with the parameter email profile, or recreate the trigger and then recreate the database. We can see the message has been queued to send, triggered by the database creation. And if I go to Outlook, I can see the message telling me all the new database has arrived.
