EMS and SNMP on a secondary lancard

[Alexandre Stefani]

Hi,

I have two lancards on each node of my cluster.
When the first card is deconnected, EMS detects it and sends an event on the console and to SNMP.
When the second card is deconnected, EMS detects it and sends an event on the console but NOT to SNMP.

via monconfig, I asked all events from all monitors to be dericted to SNMP when severity is >= INFORMATION (the lowest).

Does anyone know if EMS has this kind of behaviour, from time to time ?

Yours,

Alexandre.

Alexandre,
This issue is very complex in that you have EMS and SNMP in a Service Guard environment. It would be best to log a support case in order to troubleshoot this.

The first thing I would do is examine your version of EMS and check for SNMP patches. EMS can fail to retrieve lan/mib resources if the SNMP agent is not up to date. Next thing would be to verify your EMS configuration, as well as your SNMP in /etc/SnmpAgent.d/snmpd.conf.

We would also need to see an example of the messages that are being generated to make sure that we are affecting the correct EMS monitor (lanmond for example).

There is more to troubleshooting these areas than I alone could post here.
Best Wishes,
Cheryl Griffin

Thanks Cheryl.

In fact, I was wrong. The event is forwarded to SNMP, but not with the EMS-private OID.
The OID used is the natural MIB-II Link Down/Up.

And my NNM was badly configured. I did a little bit of sniffing to notice it.

Thanks for your help.

Alex.
