Nagios Support Forum

i am using ndo2db and mysql to store historical data, and for some reason i am losing data in mysql tables, in ndo2db.cfg, i have these below values, basically double what the default was, however (note: i currently set them to "0" as a test to see, to soon to tell), but with these values below, i lost data after a week or so, i thought the middle 3 values should allow for 2 weeks.......... any clue?

max_timedevents_age=2880
max_systemcommands_age=20160
max_servicechecks_age=20160
max_hostchecks_age=20160
max_eventhandlers_age=44640


fyi... i am using the below versions of ubuntu, nagios, ndo2db, and mysql...

You're using a fairly old version of ndoutils, I would consider upgrading to 1.5.2.

The other possibility is that you have data corruption in the database. You can run a repair with something like the following (depending on your distro).
