3.2.4 Archiving or deleting NNMi incidents
NNMi can record a maximum of 100,000 SNMP trap incidents in the database. In addition, you can use NNMi to automatically delete (trim) data starting from the oldest data, or save data to an archive to prevent an increase in data items from affecting performance.
- Organization of this subsection
(1) Checking the number of SNMP trap incidents
Check the number of SNMP trap incidents.
Procedure
In the Incident Browsing workspace, click SNMP Traps.
At the bottom of the displayed incident list, the number of SNMP trap incidents is displayed to the right of Total.
Result
You were able to check the number of SNMP trap incidents.
- Note
When the number of SNMP trap incidents is close to the upper limit, the following incidents are reported:
90% of the upper limit: SnmpTrapLimitWarning
95% of the upper limit: SnmpTrapLimitMajor
Upper limit: SnmpTrapLimitCritical
(2) Enabling the automatic trimming feature
If you enable the automatic trimming feature, data can be automatically deleted (trimmed) starting from the oldest data or an archive can be automatically created during trimming when the number of SNMP trap incidents exceeds the specified number. The automatic trimming feature is enabled by default in the new installation environment. We recommend that you enable this feature for operation.
