Is is possible to limit the usage of resources (cpu, memory etc) based on aggregated and not per process resource usage?
For example I would like to say all processes combined cannot exceed 90% memory/cpu usage, but don't include ssh (so that I can log in to fix the problem).
This would prevent both resource starvation and under-utilisation.
Am I missing something obvious? Is the question wrong to begin with?!
Thanks in advance
