Below is an overview of the statistics and notifications available from the Rhino SNMP agent, and the OIDs they use.

SNMP statistics

The Rhino SNMP agent provides access to all non-sample based Rhino statistics (all gauges and counters). Each parameter set type is represented in the form of a collection of SNMP scalar values or as an SNMP table. The OIDs for each parameter set type is by default registered according to the static OID model introduced in Rhino 3.1.0. If a parameter set type is not statically defined or the defined OIDs clash, then no OID is registered according to the static OID model. Parameter set types that don’t use the static OID model instead register OIDs according to the legacy OID model if it is enabled. For the legacy model, all parameter set types have OIDs registered except for where parameter set type OIDs conflict.

To get the OID mapping of the parameter set types and statistic names currently in the system, use the Rhino management console to export the MIB files.

SNMP collection of scalar values format

Where a parameter set type is statically defined and is associated with only a single parameter set, its statistics are represented with a collection of SNMP scalar values. Each singular value in this collection represents a counter statistic for this parameter set type.

Where a parameter set type is statically defined and is associated with multiple parameter sets, the parameter sets with statically mapped names are each represented with a collection of SNMP scalar values.

For details, see the SNMP Static OID Development Guide.

SNMP table format

Where a parameter set type is statically defined and is associated with multiple individual parameter sets, a non-statically mapped parameter set’s statistics are represented by an SNMP table. The individual table rows represent parameter sets, while the table columns represent statistics from the parameter set type. A parameter set with a non-statically mapped parameter set name will have the name of the parameter set stored as a table index in the OID.

For details, see the SNMP Static OID Development Guide.

Legacy model SNMP tables

Parameter set types that don’t use the static OID model instead have their SNMP OIDs registered according to the legacy OID model. This model supports explicitly defining static OIDs for each parameter set type with the rest dynamically generated. The legacy OID model section describes the SNMP OID allocation in further detail.


For static model non-statically mapped parameter sets and legacy model parameter sets, exceptionally long parameter set names may be truncated if their OID representation is longer than 255 characters. This is to prevent pathname length problems with management clients that store SNMP statistics in files named after the index OID.


The statistics provided by this interface can be considered the "raw" statistics values for individual Rhino nodes. The SNNP agent doesn’t collate statistics from other nodes. These retrieved statistics won’t in general reflect any activity that is occurring on Rhino nodes other than the one the SNMP agent is providing statistics for.

SNMP notifications

The Rhino SNMP agent supports sending SNMP notifications to a designated host/port. It forwards the following, which include all standard JAIN SLEE 1.1 notifications, plus several Rhino specific notifications. Rhino will send SNMP notifications if a destination host has been configured and the SNMP notification function is enabled. See Configuring SNMP Notifications for instructions on how to configure Rhino to send SNMP notifications.

The notification MIB structure is a set of SNMP variable bindings containing the time ticks since Rhino started, the notification message, type, timestamp, node IDs and additional data. These are also documented in the RHINO-NOTIFICATIONS.MIB file generated by rhino-console exportmibs.

Common Notification VarBinds (Notification argument data)
Name OID Description


The notification message. For alarms, this is the alarm message text.


The notification type. A notification type in dotted hierachical notation. For example, "".


An incrementing sequence number, indexed for each notification type.


A timestamp in ms since 1-Jan-1970.


The node IDs reporting this notification. An array of Rhino node IDs represented as a string [101,102,…​].


The source of the notification. This can be an SBB, RA entity, or subsystem.


The namespace of the notification. The field will be an empty string for default namespace.

Component state change
Name OID Description


Old state of the component.


New state of the component.


ID of the component. This can be a service or RA entity name.

Name OID Description


Alarm ID.


Alarm level (Critical, Major, Minor, etc).


Alarm instance ID.


Alarm type ID. The value of this depends on the source of the alarm. For example, a failed connection alarm from the DB Query RA would have a value like localhost (Oracle).

Name OID Description


Tracer level (Error, Warning, Info, …​).

Usage parameter notification (Rhino Statistics)
Name OID Description


Usage parameter name, one per parameter in the parameter set.


Parameter set name.


Value of the usage parameter at the moment the notification was generated.

Name OID Description


Log key.


Log level (ERROR, WARN, INFO, …​).


Thread the message was logged from.

Log file rollover
Name OID Description


The log file that was rolled over.


The new name of the log file.

A sample SNMP trap for an alarm follows. The OctetString values are text strings containing the alarm notification data.

Log notification appender

Rhino 2.2 introduced a log notification appender for use with the SNMP agent. This appender will create notifications for all log messages above its configured threshold. These notifications will in turn be forwarded by the SNMP agent to the designated host/port. This is intended as a catch-all for any errors or warnings which don’t have specific alarms associated with them.

OID hierarchy

The Rhino SNMP agent uses the following OIDs. (All statistics and notifications that it provides use these OIDs as a base.)
