1.3.6.1.4.1.19552.1.2 – Per-domain Metrics
The per-domain MIB is defined as: 1.3.6.1.4.1.19552.1.2.L.A.B.C.S.G where A.B.C indicates the domain name, and L represents the length of that domain. For example, aol.com would be represented as:
7.97.111.108.46.99.111.109 7 a o l . c o m
In this case 7 indicates the length of 'aol.com'. The length and the binding identifier replace L.A.B.C in the MIB. G corresponds to the MTAGroupIndexID (see RFC 2789, MTA MIB) S represents the metric type. We define the following metrics:
-
0: domain name
-
1: receptions
-
2: failures
-
3: deliveries
-
4: transient failures
-
5: outbound connections
-
6: active queue size
-
7: delayed queue size
For more information about Mail Monitoring MIBs see RFC2789.
The aol.com domain name would have the following entry on the default binding: 1.3.6.1.4.1.19552.1.2.7.97.111.108.46.99.111.109.0.1: string 'aol.com'
The MTAGroupIndexID can be determined by using snmpwalk and sutracting 1 from last number of the desired binding. You can also use snmpwalk to get the MTAGroupIndexID in order to determine per-domain stats.
For example:

In the output above, cdp and example are binding names. The MTAGroupIndexID of cdp is 2 because 2 is one less than the last number in SNMPv2-SMI::enterprises.19552.1.3.4.3.
