Nload software for network card traffic monitoring in Linux

Linux network card traffic monitoring software Nload installation nload: # wgethttp: // others Linux network card traffic monitoring software Nload installation nload: # wget http://www.roland-riegel.de/nload/nload-0.7.2.tar.gz# tar zxvf nload-0.7.2.tar.gz # cd nload-0.7.2 #. /configure -- prefix =/usr/local/nload & make install. set the installation directory by yourself. the installation is very simple and basically there will be no errors! Then, it can be used to monitor network card traffic: #/usr/local/nload/bin/nload

The first line is the name and IP address of the NIC by default. you can use the left and right keys on the keyboard to switch the NIC. By default, Incoming indicates the Incoming traffic to the network card. by default, Outgoing indicates the Outgoing traffic from the network card. the default value is right (current traffic of Curr), Avg average traffic, and Min minimum traffic), (Max maximum traffic), (Ttl traffic statistics). by default, the traffic chart is displayed on the left side of the statistics. the # number is spelled out and displayed based on real-time traffic changes. Problem: When the network card traffic exceeds the transmission rate of the network card, the values on the right will not change to a fixed number. I think the reason is that the network card is overloaded, so the computing error! I'm not sure. do you have any experts understanding this problem !!! There are also many parameters that can be used. examples in the help section: # nload-t 200-I 1024-o 128-U M to view the parameter help command: #/usr/local/nload/bin/nload -- help-a: the refresh time period of all data, in seconds. the default value is 300. -I: sets the maximum display ratio of the network card traffic graph. the default value is 10240 kBit/s. -m: only statistics are displayed, instead of traffic graphs. -O: sets the maximum display ratio of the traffic graph of the outbound Nic. the default value is 10240 kBit/s.-t. The interval of refreshing data is displayed, in milliseconds. the default value is 500. -U: Set the data units of Curr, Avg, Min, and Max on the right. by default, the data units are automatically changed. Note that the case sensitivity units are different! H | B | k | m | g h: auto, B: Bit/s, k: kBit/s, m: MBit/s etc. H | B | K | M | g h: auto, B: Byte/s, K: kByte/s, M: MByte/s etc. -U: Set the data unit of Ttl on the right. the default value is auto-changed. note that the case sensitivity unit is different (same as-u )! Devices: Custom monitoring network card, which is all monitored by default. use the left and right keys to switch. For example, only the eth0 command is monitored: # nload eth0
