Use Ntop to monitor network traffic ____ Network traffic reflects the running status of the network, which is the key data for determining whether the network is running normally. In the actual network, if the

the command output is shown above, the SNMP server is started normally. To work with MRTG, you must modify the snmpd configuration so that MRTG can read traffic data from its interface (Network Interface.

developed to assist in TCP Parameter Optimization, but here we do not want to study the TCP Window Scale and maximum segment length, because this is not the focus of our current discussion. However, when testing a high-throughput AP, you may find it necessary to tune TCP parameters so that you can get a larger throughput on each iPerf client-For details, see DrTCP.

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.MRTG is written in Perl and uses zlib, Gd, and PNG functions (zlib is used to compress charts and GD is used to draw charts ).

After installing the LINUX system on the server, you will not be able to access-Linux general technology-Linux technology and application information without inserting the monitor. The following is a detailed description. After the centos 5.5 5.7 64-bit installation is minimized on the server (normal installation is also attempted), you cannot directly access the

"Problem description":A business function A in the product, in the "Refresh", select order, and so on a series of operations, such as switching other rows, suddenly occurs when the client does not respond to the phenomenon.Repeated testing has revealed that it can occur in a single-user scenario, but this problem cannot be reproduced once the client has the Fiddler tool enabled. And after the problem occurs, the dump file of the crawl application server
