Hi,

it looks like irstats2 has a flaw in gathering author data. From our statistics on our test server zoratest (irstats2 is not yet deployed on the production server www.zora.uzh.ch) we get the following picture:

Most Downloaded Items:

count,eprintid,description
="10077",="10147","<a href=''>Body Modification: psychologische Aspekte von Piercings und anderen Körperveränderungen</a>"

You see immediately that this is plain wrong, because the top author, "Kälin, R" who published eprintid 10147 (see http://www.zora.uzh.ch/10147/) isn't on the list of top authors and should there have a count of 10077 downloads.

Kälin, R also doesn't appear in the Filter Items list of irstats2.

Checking the SQL tables as Seb suggested yields:

mysql> select * from eprint_creators_name where eprintid=10147\G
*************************** 1. row ***************************
eprintid: 10147
pos: 0
creators_name_honourific:
creators_name_given: R
creators_name_family: K?lin
creators_name_lineage:
1 row in set (0.00 sec)


mysql> select * from eprint_creators_id where eprintid=10147\G
Empty set (0.00 sec)


Another eprint indeed lists entries in the eprint_creators_id table:

mysql> select * from eprint_creators_id where eprintid=13208;
+----------+-----+------------------------------+
| eprintid | pos | creators_id                  |
+----------+-----+------------------------------+
|    13208 |   0 | mjackson@vetclinics.uzh.ch   |
|    13208 |   1 |                              |
|    13208 |   2 | jkuemmerle@vetclinics.uzh.ch |
|    13208 |   3 | afuerst@vetclinics.uzh.ch    |
+----------+-----+------------------------------+


Conclusion: irstats2 seems to gather author statistics only correctly, if there is creators_id entry (at least an e-mail address set) in table eprint_creators_id . Also it seems to produce a filter list entry only, if there is a corresponding entry in table eprint_creators_id.

Irstats2 authors, please correct this wrong behavior.

Best regards,

Martin

Hey,

Do you have a URL I can look at?

It seems like there are some issues with your data (the "countries' does not exist" error indicates some issues with Geo::IP). Do you get any related errors/warnings when you run "bin/epadmin test"?

If that were possible, I'd re-generate all the stats:

bin/stats/process_stats <id> --uninstall

then

bin/stats/process_stats <id> --setup --verbose

As you know, this may take some time (depending on the size of your 'access' dataset).

Kind regards,
Seb
