Background:
FTP is mainly used for file upload and download.
There are still many opportunities for FTP to display its talents in surveillance video collection and playback. In the mainstream video storage scheme of HD video surveillance industry, 720p, 1080p is the mainstream, and 4k or more is the rookie. HD will certainly make the video stream larger and larger and store longer. Ftp service to store video is a good choice.
Example demonstration
First of all, you have to prepare your own FTP server, which is a must. FTP server construction is not complicated. There will be many articles under Baidu.

Thread Group-add-configure components-FTP Request Defaults
Configure FTP Sampler (FTP request)
1) obtain the file from the server, and first change the name to get
Server name or IP: FTP server name or ip address
Port number: the FTP server port number defaults to 21
Remote File: remote file path address
For example, / home/manisha/sample_ftp/a.mp4 a.mp4 remote file must exist
Local File: save the file pulled by FTP in the local path and add a remote file name.
For example, d:/home/a.mp4 a.mp4 local home file should not exist at present.
Local File Contents: empty by default
RadioButton:
Get (RETR): download and use
Put (STOR): upload usage
CheckBox:
Use Binary mode: whether to use binary mode or not. Relatively large files are recommended.
Save File in Response: whether to save the server reply
Remarks:
If the transmission mode is not selected, jmeter will match automatically.
Take a look at the FTP server-side files:
It is more convenient and intuitive to use the FileZilla tool to view.
2) send files locally to the server
Add another FTP Sampler
Change the name to post, and the use case sends a file from the ftp server
Remote File: a specific directory uploaded to a remote FTP server.
For example, / home/sample/test.txt test.txt is not stored remotely.
Local File: local file address, such as D:/home/sample/test.txt test.txt must exist
Take a look at our local files:
3) add view result tree
View the result tree in listener-> and run to view the results.
View the local directory:
FTP server, Jmeter sampling results and local directory file size is about 14 m, the test is successful.
Story:
Rule of twenty-eight: usually 80% of the work we do is futile, and only 20% can be effective. How to prevent this from happening? The 2008 rule tells us to focus on 20% of the work and make it 80% effective.
