Not getting the same number of results in my test run - jmeter

Question

In the same Jmeter tests, I'm getting different line of results in the csv.
In one I'm getting ~80 in the others I'm getting ~800.
Is there a setting, that I'm always getting the same numbers of results in the .csv?
I'm also using slaves, so this should just scale up, with one slave it should be 80 and with 10 slaves it should be 800?
Everything is in a big CI/CD pipeline. So I tried multiple runs.
But never got the same line of results for the same test.
Here is my jmx xml.

Answer 1

You have 10 users and 100 loops in your Thread Group hence you should get 1000 total results (if everything goes well)
At the same time you have Stop Test Now after a Sampler error, it means that your test will stop immediately (and not gracefully) whenever even a single request fails
All JMeter slaves are executing the same test plan absolutely independenly so for 1 slave you will have 1000 results, for 2 slaves - 2000, for 8 slaves - 8000, etc. but again only if everything will be ok, any single failure will cause your test to immediately stop forcefully terminating the connections (and adding more errors) so you might want to switch this "Action to be taken after a Sampler error" to Continue and it will allow you to have equal amount of results each time you run your test.
