Use Network Interface attributes to monitor the rates at which bytes and packets are sent and received over the named network interface. Network Interface is a multiple-instance attribute group. You cannot mix these attributes with those of any other multiple-instance attribute group.
Bandwidth Utilization Percentage Measure of network interface bandwidth utilization. Calculated as 100 * ((8 * Bytes Total/sec) ÷ Current Bandwidth). Note: -1 indicates Unknown and 9223372036854775807 indicates Value_Exceeds_Maximum.
Bytes Received/sec The rate that bytes are received on the interface, including framing characters. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.
Bytes Sent/sec The rate that bytes are sent on the interface, including framing characters. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.

Current Bandwidth An estimate of the current bandwidth for the interface in bits per second (bps). For interfaces that do not vary in bandwidth, or for those where no accurate estimation can be made, this value is the nominal bandwidth. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.

Note: the value -1 indicates Unknown, the value 0 indicates Disabled, the value 1 indicates Enabled, the value 2147483647 indicates Value_Exceeds_Maximum and the value -2147483648 indicates Value_Exceeds_Minimum.
Friendly Name The friendly name of the Network Interface. The valid format is a text string of up to 256 characters.
IPv4 Address The IPv4 interface address. Note that the value No_DNS_Entry is a valid value.

Network Interface Instance The instance name of the Network Interface object (Connection Name). The valid format is a text string of up to 128 characters.
Output Queue Length The length of the output packet queue (in packets). If this is longer than 2, delays are being experienced and the bottleneck must be found and eliminated, if possible. Note: -1 indicates Unknown, 9223372036854775807 indicates Value_Exceeds_Maximum, and -9223372036854775808 indicates Value_Exceeds_Minimum.
Output Queue Length kPackets The length of the output packet queue in packets (in thousands). If this is longer than 2, delays are being experienced and the bottleneck must be found and eliminated, if possible. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.
Packets Outbound Discarded The number of outbound packets that were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.
Packets Outbound Errors The number of outbound packets that could not be transmitted because of errors. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.
Packets Received Discarded The number of inbound packets that were chosen to be discarded even though no errors had been detected to prevent their being delivered to a higher-layer protocol.
One possible reason for discarding such a packet could be to free up buffer space. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.
Packets Received Errors The number of inbound packets that contained errors preventing them from being delivered to a higher-layer protocol. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.
Packets Received Non-Unicast/sec The rate that non-unicast, that is, subnet broadcast or subnet multicast packets, are delivered to a higher-layer protocol. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.

Packets Sent Non-Unicast/sec The rate that packets are requested to be transmitted to non-unicast, that is, subnet broadcast or subnet multicast, addresses by higher-layer protocols. The rate includes the packets that were discarded or not sent. Note: the value 9223372036854775807 indicates Value_Exceeds_Maximum and the value -9223372036854775808 indicates Value_Exceeds_Minimum.

System Name The managed system name. The form should be hostname:agent_code.
Examples include spark:KNT or deux.raleigh.ibm.com:KNT.
In workspace queries, this attribute should be set equal to the value $NODE$ in order to populate the workspace with data. This attribute is generally not included in situations, unless there is a need to customize the situation for a specific managed system.
Timestamp The date and time the Tivoli Enterprise Monitoring Server samples the data.
