基于jMeter的SFTP服务器性能测试

Question

我需要在SFTP服务器上对某些上传/下载场景进行测试。为此，我使用apache JMeter插件SSH协议支持。我可以测试一个单一的文件上传一个用户。我很难执行这样的场景，如单用户多文件上传或多个用户使用此插件上传多个文件。有任何想法，如果有任何其他插件，以实现这一或任何替代方式？

自定义取样码

import com.jcraft.jsch.*;
import java.io.*;

def jsch = new JSch()
def session = jsch.getSession(${__property(loginUserName)}, ${__property(hostURL)}, ${__property(port)}) 
session.setConfig("StrictHostKeyChecking", "no")
session.setPassword(${__property(loginUserPassword)})
def sftpSession = session.connect()
def channel = session.openChannel("sftp")
channel.connect();
def channelSftp = (ChannelSftp)channel;
log.info("SFTP Connection with host is acquired" + channelSftp)
channelSftp.cd(${__property(sftpDestinationFolder)});
for(i = 0; i <100; i++){
    def f1 = new File(${__property(inputFileLocationOfBigFile)});
    channelSftp.put(new java.io.FileInputStream(f1), f1.getName()+i);
}
session.disconnect()

在apache服务器的GUI模式下工作很好，但是在linux盒或无头方式上运行时，会出现以下错误。

对如何解决这个问题有什么帮助吗？

Answer 1

您不能通过单个SFTP连接一次传递多个文件，需要排队等待多个文件。

但是，您可以通过单个用户或与不同用户打开多个连接，只需确保正确地参数化凭据和文件名/位置。

例如：

• 可以使用CSV数据集Config参数化凭据。
• 可以使用目录列表Config参数化文件。
