Hello, We opened several workspaces and to measure the activity on each of them over the time, I used birt reporting. Mainly I worked with the nx_logs table (event and date) to detect and count login, create or update operations. The results seemed correct when I ran queries on my server in 6.0 but on the production server nuxeo 5.6 counters are wrong. The events Document created or modified don't correspond to actual create/modify operations. Do you confirm this? Have you any ideas to correct this without changing nuxeo version immediatly? Best regards. FG.
