Java 如何在JMeter中记录JDBC响应错误

我想调试一个脚本，该脚本连接到几个JDBC连接并向它们发出JDBC请求。当它被破坏时，输出可能如下所示：

summary +     34 in 00:00:08 =    4.0/s Avg:  3890 Min:   399 Max:  7535 Err:    34 (100.00%) Active: 32 Started: 32 Finished: 0

summary =    316 in 00:01:07 =    4.7/s Avg:  6334 Min:   196 Max: 13358 Err:   316 (100.00%)

我看到了100%的错误率。所以这些错误一定出现在某个地方。但我还没弄明白。我尝试过的事情：

• 将一组不同的记录器添加到

  Log4j2.xml

  中，就像
  一样
• 将

  -Llog_level.jmeter.protocol.jdbc=TRACE

  和/或

  -LALL

  添加到我的jmeter命令中

我在jmeter.log中得到了数千行日志，但没有一行提到错误。当脚本运行时，它们的外观如下所示：

这种情况一再重复。我不明白从Jmeter中获取一条简单的错误消息有多难。

查看：

异常消息将作为响应消息添加，因此它将出现在

因此，如果您使用您选择的文本查看器打开此文件，您将在那里看到错误消息

如果您需要在中查看它们，您可以添加并使用如下代码：

if (!prev.isSuccessful()) {
    println('Sampler ' + prev.getSampleLabel() + ' failed with ' + prev.getResponseMessage())
}    

其中，

prev

代表previous，请参阅JavaDoc以了解所有可用函数，并参阅文章以了解有关JMeter API shorhands的更多信息，这些函数可用于
