When developing network applications, it's always necessary to capture network traffic. windows CE has built-in sniffer tool, netlog for this purpose. it captures network traffics to a file that can be examined with Wireshark or network monitor.
To enable it, we need to sele

1. ntopng is the next-generation ntop version. It monitors and displays network traffic in real time. Ntop is based on Libpcap and it is written in a portable way to run on UNIX platforms
In the Linux/Unix monitoring system, the real-time traffic of the network card, iftop is a goodIf you select iftop, the source, target, and port are displayed in detail. iftop provides more information than ifstat. However, if you only monitor the network card Traffic, ifsta

Server Providing external services is also a very important service. However, as the company's employees also need to occupy a large amount of traffic, the server may not be able to grab the bandwidth, seriously affecting the external services of the server, therefore, we need to restrict the Internet bandwidth of our employees to ensure that the server provides external service bandwidth.
In Windows, we can use the ipconfig command to obtain information about the NIC. in Linux, the command is ifconfig.
The information we can obtain is richer, including the traffic received and sent by the network card. It is not easy to use the C language to implement this command. As a result, the blogger consulted the relevant information, we know that the NIC i

Similarly, the "Outgoing traffic on interface {# SNMPVALUE}" in the "Project prototype" is modified similarly.
That is, replace ifInOctets and ifOutOctets with ifHCInOctets and ifHCOutOctets.
Then delete the host and re-Add the host. This time, everything is refreshed. The painted images are continuous and there is no sharp increase or decrease.

Introduction:The traffic signal is not the same as that of other processes. It mainly provides resource access control for inter-process sharing. It is equivalent to a memory flag. A process can determine whether it can access some shared resources. At the same time, the process can modify the flag. In addition to access control, it can also be

There are many open-source network monitoring tools available on the web for Linux operating systems. For example:You can use the command iftop to check bandwidth usage, netstat to view interface statistics reports, and other tools BANDWIDTHD, speedometer, nethogs, Darkstat, Jnettop, Ifstat, Iptraf, Nload and ntop and so on.But these tools are statistical card access data, if you want to find a like 360 sec
Use shell script to compute the Linux NIC traffic, the most critical point in the method:
Copy Code code as follows:
Ifconfig $eth _name | grep bytes | awk ' {print $} ' | Awk-f: ' {print $} '
The flow of input and output is obtained by Ifconfig eth0|grep bytes.
Copy Code code as follows:
/@rac2 =>dd2$ifconfig Eth0|grep bytes
RX bytes:1638005313300 (1.4 TiB) TX
