A - Active sessions only (includes sleeping SPIDs with open transactions)
B - Blocking / blocked sessions only
S - Exclude sleeping SPIDs with open transactions
X - Exclude system processes
@Database_Name : Limit the result set to a specific database (use ---------- for NULL database names)
@Exclude_Lock : Suppress lock details from the output (can increases procedure performance on busy servers; defaulted to 1)
@Exclude_Log : Suppress log details from the output (can increases procedure performance on busy servers; defaulted to 1)

Notes:
Blocking / blocked sessions will always be displayed first in the result set (when applicable)
Output:
SPID : System Process ID
Database_Name : Database context of the session
Running : Indicates if the session is executing (X), waiting ([]), inactive (blank), inactive with open transactions (•), a background task (--), or not defined (N/A)
Blocking : Blocking indicator (includes type of block, SPID list, and deadlock detection when applicable)
Status : Status of the session -> request
Object_Name : Object being referenced (blank for ad hoc and prepared statements)
