The + maximum value can not be greater than 2^64-1 + (18446744073709551615 decimal), and the minimum value can + + not be smaller than 0. The value of a CounterBasedGauge64 + has its maximum value whenever the information being modeled + is greater than or equal to its maximum value, and has its + minimum value whenever the information being modeled is + smaller than or equal to its minimum value. If the + information being modeled subsequently decreases below + (increases above) the maximum (minimum) value, the + CounterBasedGauge64 also decreases (increases). + + Note that this TC is not strictly supported in SMIv2, + because the 'always increasing' and 'counter wrap' semantics + associated with the Counter64 base type are not preserved. + It is possible that management applications which rely + solely upon the (Counter64) ASN.1 tag to determine object + semantics will mistakenly operate upon objects of this type + as they would for Counter64 objects. + + This textual convention represents a limited and short-term + solution, and may be deprecated as a long term solution is + defined and deployed to replace it." + SYNTAX Counter64 + +ZeroBasedCounter64 ::= TEXTUAL-CONVENTION + STATUS current + DESCRIPTION + "This TC describes an object which counts events with the + following semantics: objects of this type will be set to + zero(0) on creation and will thereafter count appropriate + events, wrapping back to zero(0) when the value 2^64 is + reached. + + Provided that an application discovers the new object within + the minimum time to wrap it can use the initial value as a + delta since it last polled the table of which this object is + part. It is important for a management station to be aware + of this minimum time and the actual time between polls, and + to discard data if the actual time is too long or there is + no defined minimum time. + + Typically this TC is used in tables where the INDEX space is + constantly changing and/or the TimeFilter mechanism is in + use. + + Note that this textual convention does not retain all the + semantics of the Counter64 base type. Specifically, a + Counter64 has an arbitrary initial value, but objects + defined with this TC are required to start at the value + + zero. This behavior is not likely to have any adverse + effects on management applications which are expecting + Counter64 semantics. + + This textual convention represents a limited and short-term + solution, and may be deprecated as a long term solution is + defined and deployed to replace it." + SYNTAX Counter64 + +END |
