Top Activity Dashboard

The Top Activity dashboard provides performance details for SQL operations. This dashboard contains the following tabs:

Top Hash Tab

The Top Hash information is provided in a table. The Top Hash table has the same columns and drilldowns as the Top SQL Table.

Adaptive Server uses the statement cache to store the text of cached SQL statements. This tab displays the SQL statements executed from the statement cache along with their bind variables, if they exist. Information that appears on this tab depends on a set of the following SAP ASE configuration parameters:

TIP: If enable literal autoparam is disabled, all SQL statements appear separately. Using this parameter has a number of advantages. For complete information, see your SAP ASE documentation.

For complete information about the required parameters, see “Adaptive Server Enterprise configuration parameters” in the Foglight for SAP ASE Release Notes.

Selecting an option button for an individual SQL text line shows the SQL Execution Statistics Dialog Box.. This dialog box shows the SQL details about a selected line of SQL text.

The Top Hash filters are the same as the Top SQL Filters.

The Server Statistics pane on the Top Hash tab is the same as the Server Statistics Pane on the Top SQL tab.

For more information on the Server Statistics pane, click the ? toward the top left of the pane.

Top SQL Tab

The Top SQL information is provided in a table, which is sorted by the Avg Duration (ms) column.

Table 11. Top SQL Table

Option button

Shows additional information about the selected statement. For more information, see SQL Execution Statistics Dialog Box. .

SQL Text

The SQL (Structured Query Language) statement.

SQL Executions

The number of SQL executions for this SQL statement.

Avg. Duration (ms)

The average amount of time the SQL statement took to run in milliseconds.

Max. Duration (ms)

The maximum amount of time the SQL statement took to run in milliseconds.

Min. Duration (ms)

The minimum amount of time the SQL statement took to run in milliseconds.

Avg. CPU (ms)

The average CPU time spent executing the SQL statement, in milliseconds.

Avg. Phys. Reads

Average physical reads: the average number of buffers read from disk.

Avg. Logical Reads

Average logical reads: the average number of buffers read from cache.

Avg. Packets Sent

Average packets sent: the average number network packets sent by Adaptive Server.

Avg. Wait Time (ms)

Average wait time in milliseconds: the average number of milliseconds a task has waited during execution of the SQL statement.

This filter allows you to thoroughly investigate a large number of SQL statements and is especially helpful when a long retention policy is configured. The filter applies to the Top SQL, Top Procedures and Top Hash values.

The following rules apply to the search methods:

The search is not case sensitive (for example, "abc", "Abc" and ABC" are considered to be the same string).
For example, type -sa to exclude sa user

The search process is carried out using the following steps:

The combination of a filter and the "Max rows after filter" field significantly reduces the dashboard response time, by limiting the highly time-consuming aggregation process.

Purpose The Max Response Time graph plots the SQL queries maximum response time and the SQL procedures maximum response time, for the database, over the specified time range.

SQLs Max Response Time. The maximum amount of time (in ms) it took the database to respond to a SQL statement at a given time, plotted over the specified time range.

The Server Statistics pane uses graphs and tables to present performance-related statistics and their impact, with focus on the top-consuming SQL queries and SQL procedures, for the entire ASE Server during the specified time range.

On any graph, hover over a point on a plot line for precise details about that point.

For more information on the Server Statistics pane, click the ? toward the top left of the pane.

The top procedures information is provided in a table, which is sorted by the Avg Duration (ms) column. The Top Procedures table has the same columns as the Top SQL Table. In addition, the SQL Text column provides a navigation tree for each top procedure SQL statement, which contains the procedure name data. Expanding the root procedure node lists the line numbers containing the SQL statements in the procedure for which the execution statistics are available.

Click an individual line to display the stored procedure text with its execution statistics in the Procedure Activity Drilldown. This behavior is enabled using the call back functionality. To use this feature, you need to configure a set of call back parameters. For more information, see Setting Callback Connection Properties .

Selecting an option button for an individual line shows the SQL Execution Statistics Dialog Box. This dialog box shows the SQL details about a selected procedure.

The procedures shown in this table are determined by the values set for the following Sybase_MDA agent properties:
