Creating Custom Activity Reports Using APEX_ACTIVITY_LOG

The APEX_ACTIVITY_LOG view records all activity in a workspace, including developer activity and application run-time activity. You can use APEX_ACTIVITY_LOG to view to query all activity for the current workspace. For example, you can use this view to develop monitoring reports within a specific application to provide real-time performance statistics.

Table 15-2 describes the columns in the APEX_ACTIVITY_LOG view.

Table 15-2 Columns in APEX_ACTIVITY_LOG

Column Type Description

time_stamp

DATE

Date and time that activity was logged at the end of the page view.

component_type

VARCHAR2(255)

Reserved for future use.

component_name

VARCHAR2(255)

Reserved for future use.

component_attribute

VARCHAR2(4000)

Title of page.

information

VARCHAR2(4000)

Reserved for future use.

elap

NUMBER

Elapsed time of page view in seconds.

num_rows

NUMBER

Number of rows processed on page.

userid

VARCHAR2(255)

User ID performing page view.

ip_address

VARCHAR2(4000)

IP address of client.

user_agent

VARCHAR2(4000)

Web browser user agent of client.

flow_id

NUMBER

Application ID.

step_id

NUMBER

Page number.

session_id

NUMBER

Oracle Application Express session identifier.

sqlerrm

VARCHAR2(4000)

SQL Error message.

sqlerrm_component_type

VARCHAR2(255)

Reserved for future use.

sqlerrm_component_name

VARCHAR2(255)

Reserved for future use.


To conserve space in the activity log, only the first log entry of each unique session will contain the IP address and Web browser user agent.

The following example demonstrates how to create a report that displays the total number of page views and the average page view time in the past 24 hours for application 9529, and grouped by userid:

SELECT COUNT(*), AVG(elap), userid
    FROM APEX_ACTIVITY_LOG
 WHERE time_stamp > (SYSDATE-1)
   AND flow_id = 9529
GROUP BY userid

Keep in mind that logging of activity in an Oracle Application Express instance is rotated between two different log tables. Because of this, logging information is only as current as the oldest available entry in the logs. If you want to persist your application specific log information for all time, you must either copy the log information into your own application table or implement logging directly in your application.
