If you want to be notified about cluster events, enable this feature. By default, events are not enabled.
You need to specify two parameters under the EGO event configuration section: EGO_EVENT_PLUGIN and EGO_EVENT_MASK. These parameters are already included in ego.conf with default values, but may be commented out.
EGO_EVENT_PLUGIN=eventplugin_snmp[SINK=host,MIBDIRS=EGO_TOP/mibs]
(where host represents the name of the host where the SNMP trap daemon is running).
SNMP traps enable an agent to notify the management station of significant events by way of an unsolicited SNMP message.
EGO_EVENT_PLUG_IN="eventplugin_snmp[…,TRAPPORT=port_number]"
Note that in a Linux/UNIX environment, do not use quotation marks around the event plug-in definition.
