In Unix-like systems, you can use top to view information such as system resources, processes, memory consumption, and so on. View network status You can use Netstat, nmap and other tools. To see real-time network traffic, monitor TCP/IP connectivity, and so on, you can use Iftop.What is Iftop?The iftop is a real-time traffic monitoring
Network monitoring is the most complex in all Linux subsystems, with too many factors, such as latency, blocking, conflict, and packet loss, even worse, the routers, switches, and wireless signals connected to Linux hosts all affect the overall network and it is difficult to judge whether the problem is caused by the Linux ne
balancer comparison), you can also put a group of IP different dimensions in a graph (the message system inflow outflow of traffic comparison, hit and miss number comparison).Acquisition Client DesignThe design of the acquisition client determines the ease of use of the monitoring platform, the user is often the business developers, to the minimum cost in exchange for the greatest benefit. So when we design the client we consider its ease of use from

The increasing development and popularization of computer network technology provides a global high-speed channel for information sharing. However, the current TCP/IP protocol family has potential security vulnerabilities, and its security mechanism is not sound, how to protect the resources and information in the enterprise's internal network from being arbitrarily damaged or stolen by external attackers i
functions:
Automatically identifies useful information from the network;
Converts intercepted data packets into a format that is easy to recognize;
Analyzes communication failures in the network environment;
Measure the test taker's knowledge about the time and process of network communication.

The Linux traffic monitoring software iptraf IPTraf can be used to monitor the load of an IP network. IPTraf uses the built-in Linux kernel... is a tool for monitoring network link traffic load. It uses snmp protocol to obtain the device traffic from the Linux system. Let's
When configuring the zookeeper cluster, you need to view the native IP, enter the command hostname-i will display only the host IP,Search below a commonly used command, busy when more knock command, in order to use the time to find!
I listed below the 10 basic Linux users should be aware of the network and monitoring commands. Network and
(sometimes useful)
–socket: Displaying network statistics
–TCP: Displaying commonly used TCP statistics
–UDP: Displays some dynamic data for the monitored UDP interface and its current usage
More than that, of course, Dstat comes with a few plugins that extend its functionality to a great extent. You can view some of their usage by looking at the/usr/share/dstat directory, which are commonly used:

With network virtualization, the software switches (such as Open VSwitch) on the servers act like the edge switches. So, to gain insights into the network flow behavior, it becomes important to has some sort of flow monitoring technique t o Analyze the traffic through these switches. NetFlow and SFlow are the "most widely used flow

itself does not help us highlight programs that eat too much CPU, memory, or other resources.
To achieve this goal, we will introduce Glances, a super powerful system monitoring program. She can automatically highlight programs that use the highest system resources and provide as much information as possible for Linux/Unix servers.
What is Glances?
Glances is a cross-platform command line system monitoring
participates in a set of word connections. However, due to the Pcap library, Iftop is able to filter traffic and report bandwidth usage for the selected host connection specified by the filter.$ sudo iftop-nThe n option prevents Iftop from resolving IP addresses to host names, and parsing itself can bring additional network traffic.Installing Iftop:ubuntu/debian/fedora users can obtain it from the default software library. CentOS users can get it fro
