shared network, you can collect network traffic data only by setting the network interface connected to the traffic collection point in the shared network to a hybrid working mode. Compared with the switch network, when the network is congested, the reliability of the hub network is very low, and the latency or loss of SNMP query commands and response packets ma

Introduction MRTG (Multi Router Traffic Grapher, MRTG) is a tool software used to monitor network link traffic load. It obtains device traffic information through the SNMP protocol, in addition, the traffic load is displayed to the user in HTML document containing PNG format

In Linux/Unix-like systems, you can use top to view system resources, processes, memory usage, and other information. To view the network status, you can use tools such as netstat and nmap. To view real-time network traffic and monitor TCP/IP connections, you can use iftop. What is iftop? Iftop is mainly used to display the network traffic of the local machine an

If the routers in gns3 can access the Internet, restart XP. If the vro cannot access the Internet, restart gns3. 3. How does prtg monitor network and bandwidth utilization?

Cacti self-brought traffic monitoring threshold template for "interface–traffic", can only monitor bytes, after adding thresholds, alarm traffic information in bytes units, viewing is unfriendly, you can convert Btyes to MB units by the following methods.1, add the

. cfg file. There are two methods: 1. Just delete comments and modify them to point to the device you want to monitor. You need to have a good understanding of the MIB or OID information. If possible, you can add it later. 2. It is also a simple method. You only need to use the generator maker to enable MRTG to automatically create a mrtg. cfg (configuration file ). The method is as follows: Use consumer maker Command Registrant maker public@192.168.

, click the Create button for creation. Then, in the upper-right corner, click "Create Graphs for this Host", select the network card to monitor in "Data Query" and click the Create button. At this point, we have successfully added a server in cacti, and its network card traffic monitoring, if the above configuration process is correct, we will see the corresponding network card
