But when I include the "chaos-monkey" in bootRun active profiles

bootRun {
environment SPRING_PROFILES_ACTIVE: environment.SPRING_PROFILES_ACTIVE ?: "chaos-monkey,local"
classpath = sourceSets.test.runtimeClasspath
}

 it is causing below issue

Hi Amit,

             From the error it seems some issue with the spring dependencies issues. Can you please check the version of spring boot you are using is compatible with the version of chaos monkey spring boot you are using.

  I did a setup in 2019 and it worked fine . I don't have the setup handy with me to check the versions.

Regards

Sushant Sood

Thanks a lot for quick response. It worked, After changing the chaos-monkey-spring boot version to the same as spring-boot version.

Also, I'm researching what is the best open source chaos toolkit to run experiments on pcf, I found https://docs.chaostoolkit.org/drivers/cloudfoundry/ but It don't have the assaults I'm looking for such as latency, increase memory usgae of application

Can you please suggest any open source toolkit for pcf

Thanks
