aws fis experiment template - Another stress-ng command is running, exiting...

You cannot run parallel executions of stress-ng. Hence the error.

You can instead:

• Delay the parallel runs (Run first, wait two minutes, run second, wait 3 minutes, etc)

• Check and terminate already running instances

• Use a different tool such as:

            *  sysbench
            *  Apache JMeter
            *  htop (for monitoring)
            *  cgroups (for resource control)
