+**Purpose:** Understand what's up with your SQL Server and get all sorts of useful troubleshooting information such as:
+-  A snapshot on running sessions/requests; 
+-  Current blocking information; 
+-  Optionally, SP/Query/Trigger/Function execution stats.
+
+In the output, you will find the following information in 6 sections:
+-  Uptime Information
+-  Running Sessions/Requests Report including resource usage, running statement, execution plan, blocking resource, waits and other relevant information.
+-  Waiter and Blocking Report, including information on head blocker and blocking chains.
+-  Stored procedure execution statistics.
+-  Query execution statistics.
+-  Trigger execution statistics.
+-  Function execution statistics.
+
+**Change log:**
+-  2012-09-10 Added extra information
+-  2013-02-02 Added extra information
+-  2013-04-12 Added page type information (PFS; GAM or SGAM) when wait type is PAGELATCH_ or PAGEIOLATCH_ .
+-  2013-05-23 Fixed parse page issue
+-  2013-09-16 Added mem grants information
+-  2013-10-17 Added statements to blocking and blocked sections, fixed head blocker info 
+-  2013-12-09 Fixed blocking section showing non-blocked sessions also
+-  2014-02-04 Fixed conversion issue with blocking section
+-  2014-04-09 Added information to blocking section, and fixed conversion issue
+-  2014-12-09 Handle illegal characters in XML conversion
+-  11/16/2016 Added support for SQL Server 2016 SP1 and live query plan snapshot.
+-  12/2/2016 Fixed transport-level error issue with SQL Server 2016 SP1.
+-  2/16/2016 Added NOLOCK hints.
+-  3/28/2017 Fixed missing characters in offset fetches.
+-  10/11/2017 Commented out stored procedure/query stats section to optimize for in-flight requests.
+-  10/20/2017 Added Query stats section and support for sys.dm_exec_query_statistics_xml.
+-  04/02/2019 Added support for sys.dm_exec_query_plan_stats and trigger/function stats section.
+-  04/08/2019 Made into a stored procedure usp_whatsup instead of adhoc script for ease of use.
