tools capture separate packages on the link, analyze their content, and display decoded content or packet-level statistics. These tools monitor and manage the network at the lowest level, as well as the most granular monitoring, at the expense of the process of affecting network I/O and analysis.Dhcpdump: A command-line DHCP traffic sniffing tool that captures DHCP request/reply traffic and displays decode

usage for an interface sent/received, and is displayed based on a ncurses bar chart. Sysdig: A tool that enables comprehensive, system-level debugging of individual Linux subsystems through a unified interface. Its network monitoring module can monitor online or offline, many process/host related network statistics, such as bandwidth, number of connections/req

Python for beginners-a linux User Logon monitoring tool, python-linux In the past few days, I want to learn Python. After reading some basic information, I felt a little boring, so I wanted to do something. If you think about it, just get a tool to detect

(i) Nmon tools overviewNmon is a tool for Linux server monitoring, through the Nmon, can be implemented to monitor the following parameters:--CPU usage Rate--memory, swap space utilization--Usage of network--Disk I/O, read/write speed--Network I/O speed, transmission and read/write speed--top-level process to see which applications are consuming more CPU--Network

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

If you're looking for a very easy-to-use Linux performance monitoring tool right now, I highly recommend installing and using the Nmon command-line utility.Nmon Monitoring ToolsThe Nmon is a system administrator-oriented tuning and benchmarking tool that can be used to displ

We mentioned earlier that there are many Linux system monitoring tools that can be used to monitor system performance. However, we estimate that more users may prefer tools (top commands) that are included in most Linux distributions ). The top command is a real-time task manager in Linux. it is also used to find the s

Iftop is mainly used to show the local network traffic and the flow of communication between each other, such as the size of the flow between the individual and that machine, is very suitable for proxy server and iptables server use to view network status can use Netstat, nmap and other tools. To view real-time network traffic, monitor TCP/IP connections, and so on, you can use Iftop. First, what is Iftop? Iftop is a real-time traffic

The Nmon is a system administrator-oriented tuning and benchmarking tool that can be used to display performance data about the following: Processor Memory Internet Disk File system Network File System (NFS) The process that consumes the most resources Resources Power Micro-Partitioning One of the places I really like about this tool is that it's completely inte

Turn from 51Testinghttp://bbs.51testing.com/viewthread.php?tid=116526Often see a lot of people talk about LoadRunner to Linux/aix performance monitoring too little, indeed, LR for non-Windows platform monitoring is too little, but we can use IBM's Nmon for performance analysis, this is a great tool, on the official web

Vmstat is short for VirtualMeomoryStatistics (virtual memory statistics). it monitors virtual memory, processes, and CPU activity of the operating system. He makes statistics on the overall situation of the system. The disadvantage is that he cannot conduct in-depth analysis on a process. The vmstat tool provides a low-cost system performance observation method. Because vmstat itself is a low-cost tool, on
