SQL Server troubleshooting – what happened with my database

Goal

Obtaining in the same SSMS window, information about why a database might have been unavailable or having its status changed.

My way of achieving it

Almost all of the monitoring deployed solutions these days raise tickets every time a database becomes unavailable and from the DBA operational point of view this means that we must connect and check what happened with the database and take the required actions. Of course that depending of the monitoring implementation some tickets will be closed automatically if during the second check the database becomes online but this doesn’t mean that we don’t need to try to see why the database status changed. Although we can do our investigation using GUI tools that SQL Server provides this approach has some limitations that the script used here tries to overcome. Below are some of the limitations:

– the account we use to connect to the server where SQL Server instance is running might not have rights to access the location where default trace files are stored which will make almost impossible the usage of SQL Server Profiler

– filtering or searching of SQL Server Error log files using SQL Server Log File Viewer was not designed to search or filter after multiple strings in the same time which makes the filtering or searching of the logs after string a and after string b impossible.

Because of this and other limitations I turned my attention and I tried to find other ways of searching and filtering SQL Server Error Log files and default trace and display the required information in only one window.

The output of the script in some cases will provide us enough information to see what happened while in other cases might give us only the name of the logins that were performing activities during that time.

dbstatus

The main benefit of this approach is that we can have in one window the information pertaining to that database from SQL Server Error log files and the default trace.
