I'm running FOP as an embedded service. What kind of statistics
can I get back from FOP after it has completed formatting? For
example, can I get:
-- page count
-- line count
-- byte count
-- total formatting time
-- if an error occurred, can I get how many pages successfully
formatted before the error?
-- estimated percentage complete while it is in the middle of a large formatting job?
-- any other data?
Is there a result structure that gets populated and returned when formatting occurs, such that I can get statistics back through that structure?
There is not one that I am aware of (I don't do embedded work ATM, although some in my company are doing some of that). I would suspect, that the logging tools being used may output some of this information. Barring that, I do know that FOP outputs some of this information by default (e.g., [INFO] [1], [INFO] [2], which indicate pages output). When DEBUG mode is used (-d from Command Line Interface) the number of pages in the last sequence (e.g., [DEBUG] Last page-sequence produced 2 pages.).
You could enable logging, and then have your program go through the log and parse this information. Here's some sample output for generating a PDF ffile, which has one 'flowing' page-master, and a second page-master which shows up at the end (last):
[INFO] setting up fonts
[INFO] [1]
[WARNING] Sum of fixed column widths 513070 greater than maximum specified IPD 510236
[INFO] [2]
[DEBUG] Last page-sequence produced 2 pages.
[INFO] [3]
[DEBUG] Last page-sequence produced 1 pages.
[INFO] Parsing of document complete, stopping renderer
[DEBUG] Initial heap size: 4496Kb
[DEBUG] Current heap size: 8874Kb
[DEBUG] Total memory used: 4377Kb
[DEBUG] Memory use is indicative; no GC was performed
[DEBUG] These figures should not be used comparatively
[DEBUG] Total time used: 10110ms
[DEBUG] Pages rendered: 3
[DEBUG] Avg render time: 3370ms/page
I've found a lot of examples setting up FOP and running it, but I haven't seen anything that captures statistics after the formatting is complete.
Thanks.
If you do come up with something, please post it back to the list so others may benefit.
