With IPHost Network Monitor you can run simple snmp requests against a Nortel device in your network.
colAgentQueueSize
col Agent Queue Size
This attribute has been replaced with the agentQueueSize attribute in the Lp Engineering DataStream Ov component. Upon migration, if the existing provisioned value of this attribute is the same as the system default for this type of data, no new components are added because the default is what the DataStream component already would be using. Otherwise, if the value is not the same as the system default, then for each Lp which is provisioned at the time of the migration, a DataStream is provisioned and the Ov's agentQueueSize is set to the non-default value.
