To enable, disable, and specify where to send SNMP notifications, use the following rhino-console commands.
enablesnmpnotifications
Command |
enablesnmpnotifications Description Enables SNMP notification sending (while the SNMP agent is active). |
---|
disablesnmpnotifications
Command |
disablesnmpnotifications Description Disables SNMP notification sending. |
---|
addsnmptarget
Command |
addsnmptarget <v2c|v3> <address> Description Adds the target address for SNMP notifications. |
||
---|---|---|---|
Example |
To send version v2c notifications to 127.0.0.1 port 162: [Rhino@localhost (#1)] addsnmptarget v2c udp:127.0.0.1/162 Added SNMP notifications target: v2c:udp:127.0.0.1/162
|
removesnmptarget
Command |
removesnmptarget <target> Description Removes the specified SNMP notification target. |
---|---|
Example |
To remove a target: [Rhino@localhost (#1)] removesnmptarget v2c:udp:127.0.0.1/162 Removed SNMP notifications target: v2c:udp:127.0.0.1/162 |
listsnmpnotificationtypes
Command |
listsnmpnotificationtypes Description Lists the notification types supported for SNMP notification type filtering. |
---|---|
Example |
To list notification types: [Rhino@localhost (#1)] listsnmpnotificationtypes Supported SNMP Notification types: AlarmNotification LogNotification LogRolloverNotification ResourceAdaptorEntityStateChangeNotification ServiceStateChangeNotification SleeStateChangeNotification TraceNotification UsageNotification |
setsnmpnotificationenabled
Command |
setsnmpnotificationenabled <type> <true|false> Description Specifies whether the notification type should be forwarded by the SNMP subsystem. |
---|---|
Example |
To disable [Rhino@localhost (#1)] setsnmpnotificationenabled SleeStateChangeNotification false SNMP notifications for type 'SleeStateChangeNotification' are now disabled. |
These settings have no effect if SNMP notification delivery is disabled globally. |
The notification types that can be configured to generate SNMP traps are:
-
AlarmNotification
-
LogNotification
-
LogRolloverNotification
-
ResourceAdaptorEntityStateChangeNotification
-
ServiceStateChangeNotification
-
SleeStateChangeNotification
-
TraceNotification
-
UsageNotification
Frequently it is desired to only send SNMP traps for AlarmNotification
and UsageNotification
.
In other cases ResourceAdaptorEntityStateChangeNotification
, ServiceStateChangeNotification
and SleeStateChangeNotification
are also desired.
LogNotification and, to a lesser degree, TraceNotification will cause performance degradation due to additional platform load.

Notification configuration and snmpstatus
Below is an example of output from the snmpstatus command showing notification configuration. Notification configuration ========================== Notification targets: v2c:udp:127.0.0.1/162 AlarmNotification forwarded LogNotification forwarded LogRolloverNotification forwarded ResourceAdaptorEntityStateChangeNotification forwarded ServiceStateChangeNotification forwarded SleeStateChangeNotification forwarded TraceNotification forwarded UsageNotification forwarded |
Thread pooling
By default, Rhino uses a thread pool for SNMP notifications.
The pool can be configured by setting the notifications.notification_threads
system property.
Value |
Effect |
---|---|
0 |
Disable notification threadpooling, use same thread. |
1 |
Default, a single dedicated thread for notification delivery. |
>1 |
Threadpool of N threads for notification delivery. |
