I have very old events in my event history in DFM ( version: 220.127.116.1132) - from 2006. My server is getting poor performance. How can I delete old events?
I found on NOW thay you can change the default value for "events purge interval" (under setup -> options --> events and alerts) of 6 months to lower period keeping the events in history. But if I would do that it would just take affect on the NEW events and not on the old events, so I am not able to delete the old events.
Does someone has an idea how I can delete in DFM the old events from history view?
Thanks a lot!
If you have good ideas or work-around you can write me directly to email@example.com

Changing the events purge interval will delete old events also. The purging routine runs every midnight (0000 hrs) and deletes all events (except some that are required to
show the current status of objects) that are older than the period specified as the events purge interval.
For example, if you set the eventsPurgeInterval to 3 months, at midnight today, most events generated before 18th June 2008 (approximately) would be deleted.

DFM deletes only 10000 events in one run, so it is possible that most of them remained even after changing the eventsPurgeInterval. The number of events deleted in one run (by default 10000) is modifiable using the "eventPurgeMaxEvents" hidden option. I would suggest you set this to a larger value using:
"dfm option set eventPurgeMaxEvents=100000"
or some such value.
I would suggest you record the number of events to see if the deletion succeeds. You can use:
dfm report view events-history | wc -l
dfm report view events-history | find /c /v "mxzyptlk"
to see the current count of events in the database.
You can check the number of events, set the option as specified, and then check the number of events again the next day to see if events are getting deleted.
