Checking SQL Server's Heart Beat - Page 2

Method 2

This method is useful for checking the heart beat of SQL Server services. If any of the services listed in the ServiceList.txt are not running, it will send an email.

Step1

Create a folder c:\HeartBeat and create a file ServiceList.txt as shown below with all the servers and services you would like to check.

Note: Add your server names and the corresponding service names.

Step2

Create a file c:\HeartBeat\CheckHeartbeatEmail.vbs and copy and paste the below code into the file.

Loop

ofile.writeline "Check Heart beat Completed"

Note: Make sure you change the email-Id and the SMTP server names in the VB Script described above.

Step3

Execute the above VB script. It creates a file c:\HeartBeat\Status.txt and sends emails as shown below.

Conclusion:

By Scheduling the above VB Script to run every 5 minutes or so, the Database administrators can be notified on time, when SQL service is not running. This article can also be used to monitor any services in the Windows operating system.
