     chaos.monkey.assaults.level=3

LatencyActive and ExceptionsActive assaults are low impact assault(Request type), whereas KillApp and Memory are high impact assaults(Runtime assault). So Request type assault can be triggered just by loading them whereas Runtime assault requires an additional step after loading them.

Trigger this Http endpoint and that should execute the assault: /chaosmonkey/assaults/runtime/attack

To Kill an application manually follow the below step:

1) Create the assault by:

POST: https://{{server-address}}/{{app-name}}/actuator/chaosmonkey/assaults

{
    "level": 1,
    "deterministic": false,
    "latencyActive": false,
    "exceptionsActive": false,
    "killApplicationActive": true,
    "memoryActive": false,
    "cpuActive": false }

2) Run the created assault by:

POST: https://{{server-address}}/{{app-name}}/actuator/chaosmonkey/assaults/runtime/attack

Use property value for "chaos.monkey.assaults.runtime.scope.assault.cron.expression" as cron expression like */1 * * * * ? or any valid cron expression, to enable chaos monkey runtime assaults on a schedule.

Use property value as OFF otherwise(also default value)

App kill and memory kill attacks need the attribute runtimeAssaultCronExpression set to a valid cron expression like " * * * * * * ". By default it is set to "OFF"

See documentation: https://codecentric.github.io/chaos-monkey-spring-boot/2.2.0/#_appkiller_assault
