缺少 Jmeter 日志

问题描述

我无法在记录器视图和 jmeter.log 中看到日志消息。我正在编写一个简单的 jmeter groovy 脚本 [jsr223 listener]。

org.apache.jorphan.logging.LoggingManager;
private static final Logger log = LoggingManager.getLoggerForClass();
log.info("your log message");
log.error("your error message");
println("something");
System.Out.Println("other thing");

日志

希望至少看到日志和错误消息，但没有通过。另外，我尝试了 jmeter 5.4.1 快照和相同的行为。我是窗口操作系统/jmeter 5.4。能知道我可能遗漏了什么吗？

解决方法

1. 您不需要前两行，log 是 JSR223 测试元素的预定义变量，有关详细信息，请参阅 Top 8 JMeter Java Classes You Should Be Using with Groovy 文章。
2. 最后一行应该类似于 System.out.println("other thing");
3. 最后两行不是将内容打印到日志文件中，而是打印到 STDOUT
4. 您应该会看到一条错误消息，例如 unable to resolve class Logger，如果您没有看到 - 您的侦听器根本没有被执行
