interfaceTopNNormalizationFactor
Module: INTERFACETOPN-MIB
OID (symbolic): INTERFACETOPN-MIB::interfaceTopNNormalizationFactor
OID (numeric): 1.3.6.1.2.1.16.27.1.2.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-create
Description: The value used for normalization if interfaceTopNNormalizationReq has the value 'true'.
Example: The following set of values is applied to a device with multiple Ethernet interfaces running at 10 Mbps, 100 Mbps, and 1 Gbps. interfaceTopNObjectVariable = 'ifInOctets' interfaceTopNObjectSampleType = 'deltaValue' interfaceTopNNormalizationReq = 'true' interfaceTopNNormalizationFactor = 1000000000 Applying this set of values will result in the sampled delta values to be multiplied by 100 for the 10 Mbps interfaces, and by 10 for the 100 Mbps interfaces, while the sample values for the 1 Gbps interface are left unchanged. The effective speed of the interface is taken from the value of ifSpeed for each interface, if ifSpeed is less than 4,294,967,295, or from ifHighSpeed multiplied by 1,000,000 otherwise.
At row creation the agent SHOULD set the value of this object to
the effective speed of the interface.
What is interfaceTopNNormalizationFactor?
This read-create integer, from 1 to 2147483647, supplies the value used to normalize the sampled variable when interfaceTopNNormalizationReq is true, and the agent should default it at row creation to the interface's effective speed. Admins tune this factor to control the scaling applied to raw sample values before ranking, as illustrated in the MIB's own example of using 1,000,000,000 to normalize octet deltas across mixed 10 Mbps, 100 Mbps, and 1 Gbps interfaces. For example, with this factor set to 1000000000, a 100 Mbps interface's sampled delta octets get multiplied by 10 before being compared against other interfaces in the report.
