Creating Custom Activity Reports Using HTMLDB_ACTIVITY_LOG

The HTMLDB_ACTIVITY_LOG view records all activity in a workspace (or database user account), including developer activity and application runtime activity. You can use HTMLDB_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: Columns in HTMLDB_ACTIVITY_LOG describes the columns in the HTMLDB_ACTIVITY_LOG view.

Columns in HTMLDB_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 ID.
`session_id`	NUMBER	Oracle Application Express session identifier.

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 HTMLDB_ACTIVITY_LOG
 WHERE time_stamp > (SYSDATE-1)
   AND flow_id = 9529
GROUP BY userid
