Customizing the usage logging extension

To customize the usage logging extension, you must install BIRT iHub Integration Technology. BIRT iHub Integration Technology provides the C and C++ source code that you modify to customize the usage logging extension. The usage logging extension source code file, usagelogext.c, installs in <BIRT iHub Integration Technology install folder>/ServerIntTech3
/User Activity Logging Extension.

The usagelogext.c source code implements the following functionality:

Specifies the name and extension of the usage log file, and the location or path to the file

These properties are defined as constants. For example:

#define USAGELOG_FILE_NAME "usage_log"

#define USAGELOG_FILE_EXT ".csv"

The AcStartUsageLog function implements this functionality.

Writes information about every transaction that BIRT iHub captures to a log file

The AcLogUsage function implements this functionality.

Stops logging information and releases the resources the extension uses

The AcStopUsageLog function implements this functionality.

Specifies whether the extension is multithread-safe

The AcIsThreadSafe function implements this functionality. If the extension is not multithread-safe, AcIsThreadSafe must return False. The reference implementation is not multithread-safe.
