I feel like network throughput might also be important, but I can't recall if it directly relates to VM resource utilization.

I remember a practice question where we had to analyze similar metrics, and I think a good indicator is the CPU load average being close to the number of cores.

I think we should look at the CPU and memory usage metrics, but I'm not entirely sure which specific values indicate proper utilization.

I've got a strategy for this. I'll focus on finding the Ganglia metric that shows the overall resource usage across the 3 executor nodes. That should give me the best insight into how the VMs are being utilized.

I'm a bit unsure about this one. Ganglia metrics can be complex, but I think I remember something about CPU and memory utilization being good indicators. I'll have to double-check that.

Okay, let's see. The key is to identify which metric would indicate if the executor nodes are using the VM resources effectively. I'll have to review my notes on Ganglia.

Hmm, this seems like a tricky one. I'll need to think through the Ganglia metrics and how they relate to VM resource utilization.
