When the server is doing the testing, it needs to monitor the network traffic to understand the network usage of the server at different numbers of times.We use the server environment is centos7,centos under the general use of iftop, or nethogs for network traffic monitoring. All 2 tools need to install Epel first, because this library usually does not own the operating system.Then install Epel First, using the following commands:RPM-UVH https://dl.fe

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, this year added testing and optimization to the two parts. The three images below summarize each subsystem of Linux and the tools used

: Supervisord: The service starts the Supervisord service, which calls itself to start the subroutine, responds to commands from the client, restarts the crash or exits the process, logs the output of the process, and collects event information. The configuration file for this service is/etc/supervisor/supervisord.conf Supervisorctl: The client's command-line tool, which provides a class shell interface through which you can connect to different S

Android memory monitoring tool ddms --> heap. Original address To monitor the memory usage of an application process using heap, follow these steps:1. After eclipse is started, switch to the ddms perspective and confirm that the devices view and heap view are all open;2. Connect your phone to your computer via USB. Make sure that the phone is in "USB debugging" mode instead of "Mass Storage ";3. After the c

No matter how careful you are, it is impossible to completely avoid bad code. At this time, some tools are required to help us check whether there is any place in the code that will cause memory leakage. The ddms in Android tools comes with a very good memory monitoring tool heap (here I use the ADT plug-in of eclipse, and take the real machine as an example, the situation in the simulator is similar ). To
