No impact on application when running gremlin

[ShubhangiSGaikwad]

Hello Team,
I am trying to simulate a Chaos Test using Gremlin on GCP , Depolyed a DVWA app on we Ubuntu machine (2 core / 4GB RAM) however when we run a load test to the webserver and a Chaos Test (CPU attack ,2 core , 100% 300 sec) on the Webserver , we are expecting a failure in the application.

But no error are seen at the application end .Need guidance to fail the application.
