- ::= {mtaEntry 9}
- -- MTAs typically group inbound reception, queue storage, and
- -- outbound transmission in some way. In the most extreme case
- -- information will be maintained for each different entity that
- -- receives messages and for each entity the MTA stores messages for
- -- and delivers messages to. Other MTAs may elect to treat all
- -- reception equally, all queue storage equally, all deliveries
- -- equally, or some combination of this.
- -- In any case, a grouping abstraction is an extremely useful for
- -- breaking down the activities of an MTA. For purposes of labelling
- -- this will be called a "group" in this MIB.
- -- Each group contains all the variables needed to monitor all aspects
- -- of an MTA's operation. However, the fact that all groups contain
- -- all possible variables does not imply that all groups must use all
- -- possible variables. For example, a single group might be used to
- -- monitor only one kind of event (inbound processing, outbound
- -- processing, or storage). In this sort of configuration all unused
- -- counters would be inaccessible; e.g., returning either a
- -- noSuchName error (for an SNMPv1 get), or a noSuchInstance
- -- exception (for an SNMPv2 get).
- -- Groups are not necessarily mutually exclusive. A given event may
- -- be recorded by more than one group, a message may be seen as
- -- stored by more than one group, and so on. Groups should be all
- -- inclusive, however: if groups are implemented all aspects of an
- -- MTA's operation should be registered in at least one group. This
- -- freedom lets implementors use different sets of groups to
- -- provide differents "views" of an MTA.
- -- The possibility of overlap between groups means that summing
- -- variables across groups may not produce values equal to those in
- -- the mtaTable. mtaTable should always provide accurate information
- -- about the MTA as a whole.
- -- The term "channel" is often used in MTA implementations; channels
- -- are usually, but not always, equivalent to a group. However,
- -- this MIB does not use the term "channel" because there is no
- -- requirement that an MTA supporting this MIB has to map its
- -- "channel" abstraction one-to-one onto the MIB's group abstration.
