There are a lot of performance tools on the Linux platform, a dazzling, long-term groping and experience finding the best thing to use is the proven, simple gadgets. Brendan D. Gregg, a system performance expert, updated his famous talk (Linux performance Tools) and slides on Linux in the recent LinuxCon NA 2014 conference. Compared with Brendan last year's talk,

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 tool similar to top.Official website: http://www.ex-parrot.com/~pdw/ift

Similar to top monitoring system activity, ntop is a tool used to monitor network usage in real time. Because ntop has the Web interface mode, it is easy to get started quickly in a short time, regardless of configuration or usage.

The Linux test tool tcpdump command is used to monitor TCP/IP connections and directly read data headers at the data link layer. You can specify which data packets are monitored and which control formats are to be displayed. For example, to monitor the communication between all Ethernet connections, run the following command: tcpdump-I eth0. Let's take a look at the specific content.

the core Httpry program was a set of parsing scripts for mining information out of generated log files. Most of these scripts is written as plugins for a core parsing script and include functionality for extracting search ter MS, searching for specified terms within client flows, and outputting the logs in XML among other things. It is relatively straightforward to write custom plugins for additional parsing tasks.Latest NewsThe latest release adds a number of useful features and tweaks. VLAN t
