*** Blocking and deadlock monitor ***
*** Blocking and Deadlock Monitor ***
------------------------------------------------
This script monitors blocking sessions using sp_WhoIsActive.

I have prepared this script to monitor blocking sessions with sp_whoisactive,
So first you need tocreate sp_whoisactive stored procedure,
please downad it from the link,

https://github.com/SqlAdmin/AwesomeSQLServer/blob/master/T-SQL%20Scripts/sp_whoisactive.sql

*******************************************************************************************/
**Prerequisite:**
Download and install sp_WhoIsActive from:
https://github.com/SQLadmin/AwesomeSQLServer/blob/master/T-SQL%20Scripts/sp_whoisactive.sql

********************************************************************************************/

-- To get overall info about current sessions
-- Check if sp_WhoIsActive exists
IF OBJECT_ID('sp_WhoIsActive') IS NULL
BEGIN
PRINT 'sp_WhoIsActive is not installed. Download and install it first.';
RETURN;
END

EXEC sp_whoisactive
---------------------------------------
/*** 1. Monitor blocking session ***/
---------------------------------------
-- 1. Get overall info about current sessions
EXEC sp_WhoIsActive;

EXEC sp_WhoIsActive @find_block_leaders = 1,
@output_column_list = '[dd%][session_id][database_name][login_name] [sql_text][wait_info][blocking_session_id][blocked_session_count]',
@sort_order = '[start_time] ASC';
-----------------------------------------------------
-- 2. Monitor blocking sessions
-----------------------------------------------------
EXEC sp_WhoIsActive
@find_block_leaders = 1,

@sort_order = '[start_time] ASC';
