jmeter shows error, but no errors in resuls tree

Question

Running jmeter 3. When I execute a set of http requests, The aggregate graph display shows error:

but the results tree shows all requests completed successfully.

Any suggestions?

Answer 1

Starting from JMeter version 3.2 the maximum amount of sample results View Results Tree listener can display is limited to 500. So if you have > 500 sample results in .jtl file it might be the case that failed samplers were discarded.

Try adding the next line to user.properties file:

view.results.tree.max_results=0

and restarting JMeter. Then open .jtl results file in View Results Tree listener - you should see all the results including failed ones.

See JMeter Properties Reference - Miscellaneous configuration for more details.
