@vFilter_Active_Blocked_System : Limit result set by passing one or more values listed below (can be used individually or combined in any manner):
A - Active SPIDs Only
B - Blocked SPIDs Only
X - Exclude System Reserved SPIDs (1-50)
@vFilter_SPID : Limit result set to a specific SPID
@vFilter_NT_Username_Or_Loginame : Limit result set to a specific Windows user name (if populated), otherwise by SQL Server login name
@vFilter_SQL_Statement : Limit result set to SQL statement(s) containing specific text
Notes:
Blocked SPIDs (Blocked / Blocking / Parallelism) will always be displayed first in the result set
