When selecting the 'Alarm History' Tab for an alarm the events may show
"An event occurred for model " of type " for which no event format file exists"
Release : 10.x
Component : Spectrum OneClick
This typically will occur when the event that generated the alarm has not been configured to be saved in the ArchMgr database (ddmdb).
This has been seen with some UIM alarms but can happen for any alarms whose events are not being archived.
Use the Event Configuration Editor and set the event(s) in question to archive.
Under the 'Event Options' Tab check the 'Event in Historical Database' option.
When done make sure to select the File Menu and Save
UIM Events will typically start with 0x063300
If enabling the Store Event option for a large number of events, make sure to check the impact this has on the event table in the ddmdb and the event table in OneClick's SRM database (table size/disk usage)
