Per-group (binding) Metrics, 1.3.6.1.4.1.19552.1.3

These act as a supplement to the MTA-MIB defined group statistics, so that the stat watcher can record active/delayed queues. G+1 is the MTAGroupIndexID (see RFC 2789 MTA MIB and “Determining the ID for an MTAGroupIndexID”). The metrics are as follows:

• 1.3.6.1.4.1.19552.1.3.1.G+1: counter, active queue size

• 1.3.6.1.4.1.19552.1.3.2.G+1: counter, delayed queue size

• 1.3.6.1.4.1.19552.1.3.3.G+1: counter, failed message count

• 1.3.6.1.4.1.19552.1.3.4.G+1: string, binding name (matches MTA MIB)
