Util_ConnectionSummary
By Jesse Roberge - YeshuaAgapao@Yahoo.com

Reports summaries of connections, running requests, open transactions, open cursors, and blocking at 3 different levels of aggregation detail.
Also gives the piggiest running request for each grouping along with its identifying information, query batch text, statement text, and XML query plan.
Most useful for finding SPIDs thare being hoggy right now - activity monitor gives session-scoped resource consumption, this aggregates active request scoped resource consumption.
Also useful for quickly finding blocking offenders and finding programs that are not closing connections, cursors or transactions.
Returns 3 result sets:
Server-wide Total / Summary (No Group By)
Connections and requests grouped by LoginName, HostName, Programname
Connections and requests grouped by SessionID (can have more than 1 running request at a time if MARS is enabled)
Orders by ActiveReqCount DESC, OpenTranCount DESC, BlockingRequestCount DESC, BlockedReqCount DESC, ConnectionCount DESC, {group by column(s)}
Can run from a central 'admin' database location.
Requires VIEW_SERVER_STATE permission to work. DB-owner does not have this permission.
Sysadmin does have this permission. VIEW_SERVER_STATE can be granted as a separate permission to some or all dbo users.

Update 2009-04-28:
Now also gives the piggiest running request for each grouping along with its
identifying information, query batch text, statement text, and XML query plan.

Update 2009-09-21:
Fixed piggiest running request - Forgot the DESC in the ORDER BY
Tweaked the pigging score - cpu*(reads+writes) is now cpu*(reads*10+writes*10+logical_reads)
Added StatementStartPos, StatementEndPos, and StatementTextLength

Update 2009-10-15:
Added PendingIOCount, PiggiestRequestDatabseID, and PiggiestRequestDatabaseName
