This -- information is taken from the NVT ASCII character -- set. It is suggested that this name contain one or -- more of the following: IP address, management station -- name, network manager's name, location, or phone -- number. -- In some cases the agent itself will be the owner of -- an entry. In these cases, this string shall be set -- to a string starting with 'monitor'. -- -- SNMP access control is articulated entirely in terms -- of the contents of MIB views; access to a particular -- SNMP object instance depends only upon its presence -- or absence in a particular MIB view and never upon -- its value or the value of related object instances. -- Thus, objects of this type afford resolution of -- resource contention only among cooperating managers; -- they realize no access control function with respect -- to uncooperative parties. -- -- By convention, objects with this syntax are declared as -- having -- -- SIZE (0..127) EntryStatus ::= INTEGER { valid(1), createRequest(2), underCreation(3), invalid(4) } -- The status of a table entry. -- -- Setting this object to the value invalid(4) has the -- effect of invalidating the corresponding entry. -- That is, it effectively disassociates the mapping -- identified with said entry. -- It is an implementation-specific matter as to whether -- the agent removes an invalidated entry from the table. -- Accordingly, management stations must be prepared to -- receive tabular information from agents that -- corresponds to entries currently not in use. Proper -- interpretation of such entries requires examination -- of the relevant EntryStatus object. -- -- An existing instance of this object cannot be set to -- createRequest(2). This object may only be set to -- createRequest(2) when this instance is created. When -- this object is created, the agent may wish to create -- supplemental object instances with default values -- to complete a conceptual row in this table. Because -- the creation of these default objects is entirely at -- the option of the agent, the manager must not assume -- that any will be created, but may make use of any that -- are created. Immediately after completing the create -- operation, the agent must set this object to -- underCreation(3). -- -- When in the underCreation(3) state, an entry is -- allowed to exist in a possibly incomplete, possibly -- inconsistent state, usually to allow it to be -- modified in mutiple PDUs. When in this state, an -- entry is not fully active. Entries shall exist in -- the underCreation(3) state until the management -- station is finished configuring the entry and sets -- this object to valid(1) or aborts, setting this -- object to invalid(4). If the agent determines that -- an entry has been in the underCreation(3) state for -- an abnormally long time, it may decide that the -- management station has crashed. If the agent makes -- this decision, it may set this object to invalid(4) -- to reclaim the entry. A prudent agent will -- understand that the management station may need to -- wait for human input and will allow for that -- possibility in its determination of this abnormally -- long period. -- -- An entry in the valid(1) state is fully configured and -- consistent and fully represents the configuration or -- operation such a row is intended to represent. For -- example, it could be a statistical function that is -- configured and active, or a filter that is available -- in the list of filters processed by the packet capture -- process. -- -- A manager is restricted to changing the state of an -- entry in the following ways: -- -- create under -- To: valid Request Creation invalid -- From: -- valid OK NO OK OK -- createRequest N/A N/A N/A N/A -- underCreation OK NO OK OK -- invalid NO NO NO OK -- nonExistent NO OK NO OK -- -- In the table above, it is not applicable to move the -- state from the createRequest state to any other -- state because the manager will never find the -- variable in that state. The nonExistent state is -- not a value of the enumeration, rather it means that -- the entryStatus variable does not exist at all. -- -- An agent may allow an entryStatus variable to change -- state in additional ways, so long as the semantics -- of the states are followed. This allowance is made -- to ease the implementation of the agent and is made -- despite the fact that managers should never -- excercise these additional state transitions. rStatistics OBJECT IDENTIFIER ::= { rmonMib 1 } rHistory OBJECT IDENTIFIER ::= { rmonMib 2 } rAlarm OBJECT IDENTIFIER ::= { rmonMib 3 } rEvent OBJECT IDENTIFIER ::= { rmonMib 9 } -- The Ethernet Statistics Group -- -- Implementation of the Ethernet Statistics group is -- optional. -- -- The ethernet statistics group contains statistics -- measured by the probe for each monitored interface on -- this device.

Because SNMP access control is articulated entirely in terms of the contents of MIB views, no access control mechanism exists that can restrict the value of this object to identify only those objects that exist in a particular MIB view. Because there is thus no acceptable means of restricting the read access that could be obtained through the alarm mechanism, the probe must only grant write access to this object in those views that have read access to all objects on the probe. During a set operation, if the supplied variable name is not available in the selected MIB view, a badValue error must be returned. If at any time the variable name of an established alarmEntry is no longer available in the selected MIB view, the probe must change the status of this alarmEntry to invalid(4). This object may not be modified if the associated alarmStatus object is equal to valid(1)." ::= { rAlarmEntry 3 } rAlarmSampleType OBJECT-TYPE SYNTAX INTEGER { absoluteValue(1), deltaValue(2) } ACCESS read-write STATUS mandatory DESCRIPTION "The method of sampling the selected variable and calculating the value to be compared against the thresholds. If the value of this object is absoluteValue(1), the value of the selected variable will be compared directly with the thresholds at the end of the sampling interval. If the value of this object is deltaValue(2), the value of the selected variable at the last sample will be subtracted from the current value, and the difference compared with the thresholds. This object may not be modified if the associated alarmStatus object is equal to valid(1)." ::= { rAlarmEntry 4 } rAlarmValue OBJECT-TYPE SYNTAX INTEGER ACCESS read-only STATUS mandatory DESCRIPTION "The value of the statistic during the last sampling period. For example, if the sample type is deltaValue, this value will be the difference between the samples at the beginning and end of the period. If the sample type is absoluteValue, this value will be the sampled value at the end of the period. This is the value that is compared with the rising and falling thresholds. The value during the current sampling period is not made available until the period is completed and will remain available until the next period completes." ::= { rAlarmEntry 5 } rAlarmStartupAlarm OBJECT-TYPE SYNTAX INTEGER { risingAlarm(1), fallingAlarm(2), risingOrFallingAlarm(3) } ACCESS read-write STATUS mandatory DESCRIPTION "The alarm that may be sent when this entry is first set to valid. If the first sample after this entry becomes valid is greater than or equal to the risingThreshold and alarmStartupAlarm is equal to risingAlarm(1) or risingOrFallingAlarm(3), then a single rising alarm will be generated. If the first sample after this entry becomes valid is less than or equal to the fallingThreshold and alarmStartupAlarm is equal to fallingAlarm(2) or risingOrFallingAlarm(3), then a single falling alarm will be generated. This object may not be modified if the associated alarmStatus object is equal to valid(1)." ::= { rAlarmEntry 6 } rAlarmRisingThreshold OBJECT-TYPE SYNTAX INTEGER ACCESS read-write STATUS mandatory DESCRIPTION "A threshold for the sampled statistic.

A single event will also be generated if the first sample after this entry becomes valid is greater than or equal to this threshold and the associated alarmStartupAlarm is equal to risingAlarm(1) or risingOrFallingAlarm(3). After a rising event is generated, another such event will not be generated until the sampled value falls below this threshold and reaches the alarmFallingThreshold.

A single event will also be generated if the first sample after this entry becomes valid is less than or equal to this threshold and the associated alarmStartupAlarm is equal to fallingAlarm(2) or risingOrFallingAlarm(3). After a falling event is generated, another such event will not be generated until the sampled value rises above this threshold and reaches the alarmRisingThreshold.
