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

Question

Hi,

I am using aws FIS for two actions: cpu stress and memory stress in one experiment template where memory stress starts after cpu stress. CPU stress completes successfully, the moment memory stress action starts it fails with error - Another stress-ng command is running, exiting...

Please suggest or guide.

Thanks.

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)
