Network (NUK_Guest_Network)
Attributes (parameters)
The following attributes are available for this application class:
Name | Description | Unit | Default Performance Key Indicator (KPI) |
---|---|---|---|
Bandwidth utilization (BandwidthUtilization) | This parameter provides details about the bandwidth usage of the network interface. The bandwidth utilization is the percentage of bandwidth utilized out of the total bandwidth available. Note: This parameter is deactivated and not displayed if it is unable to access the values provided by ethtool or dmesg tool in sudo mode. If it is discovered and is unable to receive any values from the tools then it will remain displayed. | % | Yes |
Incoming errors (IncomingErrors) | This parameter displays the percentage of incoming data packets that contain packet format errors. A large number of incoming data packets with format errors usually indicates faulty hardware on the network. Another possibility is that your system's device driver cannot receive packets fast enough. The following formula is used to calculate the Incoming Error Percent: NetInErrPrc = (DELTAIerrs/DELTAIpkts) * 100 where,
Recommendations Determine if the problem is local or elsewhere on the network by using the spray command. (You should only use the spray command during non-peak times due to the load this command places on your network.) If the problem is local to your system, the problem could be a faulty network card, or your network card may not be able to handle the capacity. In either case, you should replace your network card with one that can handle the needed capacity. If the problem is elsewhere in the network, you need to track down and replace the faulty hardware. No range thresholds have been set for this parameter. Your experience with your system and network should help you determine useful range thresholds. | % | No |
Incoming packets (IncomingPackets) | This parameter displays the total number of incoming packets during the sample interval. | pkts | No |
Rate of total data transferred by the network interface (IORate) | This parameter displays the total number of received and transmitted Kilobytes per second in the last interval. | KB/sec | Yes |
Outgoing errors (OutgoingErrors) | This parameter displays the percentage of outgoing data packets that contain packet format errors. A large number of outgoing packet format errors indicates a faulty local network interface. The fault could be in the system's network controller, the Ethernet drop, or something else between the main Ethernet cable and your CPU. The following formula is used to calculate Outgoing Error Percent: NETOutErrPrc = (DELTAOerrs/DELTAOpkts) * 100 where,
Recommendations Track down and replace the faulty hardware. Range Thresholds No range thresholds have been set for this parameter. Your experience with your system and network should help you determine useful range thresholds. | % | No |
Outgoing packets (OutgoingPackets) | This parameter displays the total number of out going packets during the sample interval. | pkts | No |
Rate of data received by the network interface (ReceiveRate) | Displays the total number of kilobytes received per second by the network interface. | KB/sec | No |
Rate of data transmitted by the network interface (TransmissionRate) | Displays the total number of kilobytes sent per second by the network interface. | KB/sec | No |
