Measurement
Unit |
Interpretation |
| Incoming_traffic |
Indicates the rate at which data (including framing characters) is received on a network interface. |
Mbps |
An abnormally high rate of incoming traffic may require additional analysis. |
| Outgoing_traffic |
Represents the rate at which data (including framing characters) is sent on a network interface. |
Mbps |
An abnormally high rate of outgoing traffic may require additional analysis. |
| Max_bandwidth |
An estimate of the capacity of a network interface. |
Mbps |
  |
| Bandwidth_usage |
Indicates the percentage of bandwidth used by a network interface. |
Percent |
By comparing the bandwidth usage with the maximum bandwidth of an interface, an administrator can determine times when the network interface is overloaded or is being a performance bottleneck. |
| Output_queue_length |
Indicates the length of the output packet queue (in packets). |
Number |
If this is longer than 2, delays are being experienced and the bottleneck should be found and eliminated if possible. |
| Outbound_packet_errors |
The number of outbound packets that could not be transmitted because of errors. |
Number |
Ideally, number of outbound errors should be 0. |
| Inbound_packet_errors |
The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol. |
Number |
Ideally, number of inbound errors should be 0. |
