Thresholds - all lost over night

Hi,

Something happened and we have lost all our thresholds for all devices. The thresholds are not present anymore in the templates. This has happened for all templates in the same time - the standard ones (cisco, windows 2003, all). They are all missing - those built in the original templates but also those modified / added by me.

If i go to the a specific monitor I can see the status of the threshold as "normal" in green but if i try to edit the threshold there is nothing as threshold alert or rearm. Attached some picture.

I didn't notice this and this morning I have updated the OP-Manager from 8720 to 8721.

Please let me know how this can be solved as we are missing important alerts without those thresholds.

P.S.: the DB is on MS SQL.

Thanks and Regards,
Razvan Despa
