Network Interface (NT_NETWORK)
Attributes (parameters)
The following attributes are available for this monitor type:
Name | Description | Unit | Default Performance Key Indicator (KPI) |
---|---|---|---|
Bytes received/sec (NETniBytesRcvdPerSec) | Displays the rate that bytes are received on the interface; this rate includes framing characters. | Bytes | No |
Bytes sent/sec (NETniBytesSentPerSec) | Displays the rate that bytes are sent on the interface; this rate includes framing characters. | Bytes | No |
Bytes total (NETniBytesTotalPerSec) | Displays the rate that bytes are sent and received on the interface; this rate includes framing characters. RecommendationsThe packet size is NETniBytesTotalPerSec/NETniPcktsPerSec. If the packet size drops, collisions are probably occurring and network efficiency is decreasing. The collisions may be caused by such things as a large number of users in a poorly configured network, or by a defective network card (NIC) that is sending excessive messages. Consider running a diagnostic test on your NIC to check for configuration or hardware errors. Most NIC manufacturers provide a diskette that contains testing software. Thresholds for alarms and warningsNo default thresholds have been set for this parameter. The baselining overview help you determine appropriate settings for your system. | Bytes | No |
Current bandwidth (NETniCurrentBandwidth) | Displays an estimate of the computer's current bandwidth in bits per second (bps). | Megabit/sec | No |
Kilo bytes received/sec (NETniKBRcvdPerSec) | Displays the number of kilobytes transferred in from a network interface per second. | KB/sec | No |
Kilo bytes sent/sec (NETniKBSentPerSec) | Displays the number of kilobytes transferred out of a network interface per second. | KB/sec | No |
Kilo bytes total (NETniKBTotalPerSec) | Displays the rate at which kilobytes are sent and received on the interface. This rate includes framing characters. RecommendationsThe packet size is NETniKBTotalPerSec. If the packet size drops, collisions are probably occurring and network efficiency is decreasing. The collisions may be caused by such things as a large number of users in a poorly configured network, or by a defective network card (NIC) that is sending excessive messages. Consider running a diagnostic test on your NIC to check for configuration or hardware errors. Most NIC manufacturers provide a diskette that contains testing software. Thresholds for alarms and warningsNo default thresholds have been set for this parameter. | KB/sec | Yes |
Network utilization (NetniNetworkUtilization) | Displays the percentage of total network usage with respect to the network connection speed. | % | Yes |
Output queue length (NETniOutputQueueLength) | Displays the length in packets of the output packet queue and can indicate network bottlenecks. RecommendationsIf this parameter's value is consistently greater than two, then the local NIC (network interface card) may be malfunctioning or the network is experiencing a collision condition that is decreasing network efficiency. These collisions may be caused by having a large number of users in a poorly configured network or by a defective network card or printer that is sending excessive messages.
| Length | No |
Packets/sec (NETniPcktsPerSec) | Displays the rate that packets are sent and received on the network. RecommendationsThe packet size is NETniBytesTotalPerSec/NETniPcktsPerSec. If the packet size drops, collisions are probably occurring and network efficiency is decreasing. The collisions may be caused by such things as a large number of users in a poorly configured network, or by a defective network card (NIC) that is sending excessive messages. Consider running a diagnostic test on your NIC to check for configuration or hardware errors. Most NIC manufacturers provide a diskette that contains testing software. | Packets | No |
Packets received/sec (NETniPcktsRcvdPerSec) | Displays the rate that packets are received on the network. | Packets | No |
Packets sent/sec (NETniPcktsSentPerSec) | Displays the rate that packets are sent on the network. | Packets | No |
Packets outbound errors (NETniPktsOutboundErrors) | Displays the number of outbound packets that could not be sent as a result of errors. | Errors | No |
Packets received errors (NETniPktsRcvdErrors) | Displays the number of inbound packets that contained errors. As a result, the errored packets were not delivered to a higher-layer protocol. | Errors | No |
