JMeter TCP采样器错误报告500 [英] JMeter TCP Sampler incorrectly reports 500

问题描述

我正在使用JMeter使用TCP Sampler(BinaryTCPClientImpl类)触发HELO来负载测试我们的SMTP服务器，等待30秒然后退出.

I'm using JMeter to load test our SMTP server using the TCP Sampler (BinaryTCPClientImpl class) to fire HELOs, wait for 30 seconds and then QUITing.

SMTP服务器接受HELO并做出相应的响应，并使用JMeter记录正确的响应，但是它似乎找不到响应，而是命中响应超时，并显示500个请求失败.

The SMTP server accepts the HELO and responds accordingly, with JMeter logging the correct response, however it does not appear to find then of the response and instead hits the response timeout and shows a 500 fail for the request.

在JMeter日志中显示:

In the JMeter logs it says:

ERROR - jmeter.protocol.tcp.sampler.TCPSampler:      org.apache.jmeter.protocol.tcp.sampler.ReadException:
at org.apache.jmeter.protocol.tcp.sampler.BinaryTCPClientImpl.read(BinaryTCPClientImpl.java:137)

尽管它设法记录了预期的响应，但仍然如此！

This despite the fact it managed to log the expected response!

我猜JMeter在某种程度上未能发现响应的结束?

I'm guessing JMeter has somehow failed to spot the end of the response?

任何有关如何解决或调试此问题的想法将不胜感激.

Any thoughts in how to solve or debug this would be much appreciated.

推荐答案

如果您未定义

If you don't define the EOM byte, it reads until the end of the stream. Since the stream isn't going to end, it times out. You have to set the EOM byte correctly for the protocol you're using.
