Note: SigmaSystemCenter handles PET as an OOB Management event. PET is a type
of SNMP Trap.
Even if SigmaSystemCenter receives an OOB Management event corresponding to
SNMP Trap, SigmaSystemCenter does not display the event on the Web Console in
some cases because such events are filtered by SigmaSystemCenter internally.
The following table shows the conditions for discarding SNMP Trap.
# Case of discarding SNMP Trap
1 SigmaSystemCenter discards SNMP Trap except PET.
SNMP Trap has a value called "Enterprise".
The "Enterprise" of PET is "1.3.6.1.4.1.3183.1.1".
2 SigmaSystemCenter discards PET retransmitted.
It happens that the BMC retransmit PET to SigmaSystemCenter.
In this case, SigmaSystemCenter checks the value of PET called "Sequence
Number".
If the sequence number of PET is equal to the previous, SigmaSystemCenter
discards the latter.
4 SigmaSystemCenter discards PET from a machine managed by ESMPRO.
5 SigmaSystemCenter discards PET from the sensor which SigmaSystemCenter has
no information of.
6 SigmaSystemCenter discards PET from the machine whose account information is
not set.
7 SigmaSystemCenter discards PET which seems to mean the same event as the
previous one.
8 SigmaSystemCenter discards PET which doesn't exist on the list above.
1.2.9. Events the Hyper-V Cluster Function Can Detect
The events that the Hyper-V Cluster function can detect from Microsoft Failover Cluster
are as follows.
You can check the following error events by specifying the category in the Event
Category and "HyperVProvider" in the Report Source.
