Use MRTG to detect linux Network Performance

Use MRTG to check linux network performance-Linux Enterprise Application-Linux server application information. The following is a detailed description. To fully measure the network running status, you need to make more detailed and accurate measurements on the network status. This article describes how to use the SNMP-based typical network Traffic statistical analysis tool MRTG (MultiRouter Traffic Grapher, MRTG.

With the increasing popularity of linux applications, a large number of network servers use the Linux operating system. To fully measure the network running status, you need to make more detailed and accurate measurements on the network status. The establishment of the SNMP protocol provides powerful support for Internet measurement. MultiRouter Traffic Grapher (MRTG) is a typical network Traffic statistical analysis tool based on SNMP. It consumes a small amount of system resources, so many plug-ins are also attached to MRTG. It obtains traffic information from the device through the SNMP protocol, and displays the traffic load to the user in HTML document containing JPEG format, which is very intuitive.

Working Principle

Total data traffic of network servers (total data transfer of network cards), CPU usage, and packet transfer rate (or traffic) of special services (such as Squid proxy service) it is a must for network administrators. When the CPU usage of the host is too high, the system may be unstable, so you need to pay attention to which service or who is trying to steal our data. Therefore, in terms of network management, it is necessary to understand the traffic status of our hosts and limit or increase bandwidth based on traffic.

We can download the MRTG software from the http://www.mrtg.org. Go to http://www.stat.ee.ethz.ch/mrtg/to get the output result of the mrtgtraffic monitoring chart. Example 1.
