We have noticed that the time and count of alarms in USM are not getting updated as they should. As mentioned in the KB34697 I have set the supp_divisor to a certain value, but USM isn't respecting it.
Release : UIM 9.2.0
Component : UIM - UMP_USM
For improving USM performance NAS 9.2 introduces a new key.
The new is called "nis_update_skip_factor = 100"
(by default it comes with value 100)
This configuration forces the NAS_ALARMS in the UIM DB (the alarms that show in USM) to update every 100 occurrences, even if the local alarms (database.db - the alarms that show in IM) are increasing the count at higher rate count as determined by the Example: supp_divisor = 1" key. (at every occurreance of the same alarm).
The "nis_update_skip_factor equals to 100 makes identical suppressed alarms to update in USM every 100 occurrences.
To disable this new configuration key please set it to "nis_update_skip_factor = 0"
When disabling the function, USM alarms will update the count following the supp_divisor key, as described in KB34697
