Jmeter 'View Results In Table' logging only partial requests

Question

I am running a test on Jmeter (Version 4.0) using Throughput Shaping Timer in order to achieve constant rate of hits per second. I am logging all the data of 'view Results in table' to a file and using it to track all the requests.

The functionality of my application is such that When jmeter hits API , it creates a database entry for each of the hit.

After test execution is finished, I can see that number of results in log of 'View Results in Table' is less than the number of database entries created by jmeter test run. Also, I am able to arrive at the requests which are not present in logs, but are present in database.

Does 'View Results in Table' not save all the requests ? How can this be changes to obtain data of all the requests ?

Answer 1

As per View Results Tree listener documentation:

Starting with version 3.2 the number of entries in the View is restricted to the value of the property view.results.tree.max_results which defaults to 500 entries. The old behaviour can be restored by setting the property to 0. Beware, that this might consume a lot of memory.

You can disable the limitation by adding the next line to user.properties file:

view.results.tree.max_results=0

JMeter restart will be required to pick the property up.
