Table 21. Top User Table Description
Name	Description
Login Name	The login name of the top user.
CPU Time (ms)	The CPU time (in milliseconds) used by the process.
Memory Usage (kB)	The amount of memory (in kilobytes) allocated to the process.

SQL Text Table

This table has the same columns as the Top SQL Table. The only difference is that the SQL Text table provides data for selected user-executed SQL statements.

Current Top Sessions Tab

Current top session information is provided in three tables:

•

Top Sessions Table

•

Top SQL of Session with SPID Table

•

Wait Events of SPID xx for Period Table

You can filter the Current Top Sessions according to the Wait Classes, by clicking Choose Resource. Then select a resource from the list of the Wait Classes for events that occurred in the time period. This allows you to view only those processes for which that specific Wait Class occurred. The possible wait classes are:

•

Workload

•

waiting for a disk write to complete

•

waiting for a disk read to complete

•

waiting to be scheduled

•

waiting for memory or a buffer

•

waiting to output to the network

•

waiting for internal system event

Top Sessions Table

The Top Sessions table lists all of the top sessions.

The filters appearing just above the table allows you to look for specific entry based on some known criteria. You can filter on:

•

System or user processes

•

Time range, by selecting Since Logon, Last Sample, or Last 10 min

Click the Login Name for a session to view a popup that provides real-time monitoring details about the associated process.

Figure 18. SPID Details

These details include the time (in milliseconds) that has elapsed since the process was last run. Values for other statistics since the process was last run are provided in brackets.

Select an option button on the Top Sessions table to specify the SPID (session process identifier) number.
