Data pump Timing details

One of my export  job running more than 8 hours but did not seen any progress on log file and dumpfile .  after  googling i found below help full  undocumented parameter METRICS .

With the undocumented parameter METRICS additional information can be obtained about the number of objects that were processed and the time it took for processing them. Objects in this context are for example the exported system GRANT privileges, the imported tablespace quota GRANT statements, the exported CREATE TABLE statements. Note that the METRICS parameter does not create any additional trace files. Instead, the extra details are logged in the logfile of the Export Data Pump or Import Data Pump job.

Example output:

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production

FLASHBACK automatically enabled to preserve database integrity.
