The company has to do stress testing, there is a Linux server, system Centos6.5, in order to intuitively show system performance, better to analyze the server, so to build a monitoring. Stop gossiping and get to the point.

First of all, a Linux server: system Centos6.5

Second, install the monitoring software client on my laptop

To configure spotlight login users, note that spotlight cannot use root users to connect by default. Users need to create a user with root permissions. Baidu is the only way to assign permissions to new accounts. Here, we focus on building a performance monitoring Spotlight on Unix under linux Centos.

(1) useradd spotlight

(2) passwd spotlight

(3) vim / etc/passwd

(4) change the UID and GID of spotlight to 0:0

Next, let's start installing sysstat on the server.

Use iostat, mpstat, sar

Yum install sysstat-y

The installation package of sysstat is: sysstat-9.0.4-20.el6.x86_64.rpm. After installation, there will be functions of iostat, mpstat, sar and sa.

Start sysstat

/ etc/init.d/sysstat start

Set sysstat self-startup

Chkconfig sysstat on

-

The main command provided by the sysstat toolkit: iostat mpstat sar

Mpstat, the abbreviation of Multiprocessor Statistics, is a real-time system monitoring tool. It reports along with some statistics for CPU, which are stored in the / proc/stat file. In a multi-CPUs system, it can view not only the average status information of all CPU, but also the information of a specific CPU. Only the parameters related to CPU of mpstat are described below. The syntax of mpstat is as follows:

Mpstat [- P {| ALL}] [internal [count]]

Mpstat-P 0 1 5

Mpstat-P ALL 1 5

The method of viewing the traffic of network card

Sar-n DEV 1 5

The last 1 / 4 of the command means: take the value once every second, take 5 times. IFACE:LAN interface
