In JMeter logs are not displayed in Log viewer

Question

Whenever I ran the test logs are not displayed in log viewer panel in application, logs are displayed in command prompt.

• Can anyone pls suggest for this issue?
• How can I see logs in log viewer panel instead of cmd prompt?

I was enabled logviewer check box also.

Answer 1

You may add JSR223 Sampler and write this code in Groovy:

println("Test message");

In that case you will see message in cmd console window.

If you want to print your message to JMeter Log Viewer use this code instead:

log.info("Test message:" + vars.get("yourVariableName"));

Answer 2

Most probably your JMeter Logging Configuration is corrupt, either try re-installing JMeter by downloading a "fresh" version or replace log4j2.xml file contents with the one from JMeter source repository
