Jmeter-Java real request

1.1.  Jmeter-the Java plug-in implementation interface test

(linux /mysql/rabbit-mq)

 

The need to prepare the environment

Eclipse+jdk8

Jmeter

Python

1.1.1.  R & lt abbit-MQ Web client brief 

Rabbit-mq a demo video of the installation See

 

Production speed: generating a speed of the message, write the message queue

Consumption rate: rate of consumption of the message, the message queue of outgoing

 

 

 

 

1.1.2.  Nmon monitor usage

(1)  as an administrator installed in each server node nmon

yum install nmon

 

(2)  run nmon monitoring

nmon –f –s 10 –c 1200

 

Parameter Description:

-f output file

-s interval of time how many seconds to obtain monitoring data

To obtain a total of how many times -c data

Background process

nohup nmon –f –s 10 –c 1200 &

 

(3) monitor the end of the run

sort …..nmon >> ….csv

 

The nmon monitor file is converted into csv format, and then by ssh-ftp tool to take windows under use nmon Analyzer tool csv file into a excel file format, and saved, the file can be opened view monitoring data.

Monitors the output file excel file analysis shows

The main view SYS_SUM pages (see the cpu utilization, disk IOPS , and IO-the Wait% )

(cpu utilization Means 70% or less, a normal disk iops in 4000 or less, the IO-the Wait% average at 10% or less )

 

 

 

 

 

1.1.3.  Python Screenshots

Since rabbitmq client data is updated in real time, so you want to keep the data in the testing process, the need for the client screen shots.

Using python script to automatically capture

(1)  Configure the local python environment

(2)  Installation python theme module

pip install image

 

(3)  write python Screenshot script, save it as Image .py file

Script Example:

import time

from PIL import ImageGrab

 

for i range(1200):

    im = ImageGrab.grab()

    addr = str(time.strftime("%Y-%m-%d-%H-%M-%S", time.localtime()))+str('.jpg')

    im.save(addr,'jpeg')

time.sleep(5)

 

(4) a copy of the script to a writable directory (note empty directory best, and there is enough space), run the script

python image.py

In the script directory will generate screenshot every 5 Miao picture

1.1.4.  Write rabbitmq producers plug

(1)  local environment eclipse

(2) Create Project
