Disk I/O rates are important. They show if we're reading/writing efficiently.

Network throughput matters. High values indicate good resource use.

I think memory usage is key too. Should be close to 75%.

CPU usage percentage should be around 70-80%.

I’m not sure, I thought lower CPU usage was better for performance.

Wait, isn't 100% utilization a sign of overloading?

I think memory usage is more important, though.

CPU utilization around 70% is ideal.

Monitoring the Ganglia metrics is like playing resource utilization Tetris, gotta keep an eye on all the pieces!

Haha, I bet the Ganglia developers had a field day coming up with those metric names!

Checking the network I/O metrics could also provide insights into the cluster's resource utilization.

I'd look at the memory usage metric to see if the VMs are being utilized efficiently.

The CPU utilization metric would be a good indicator of proper VM resource utilization.

From what I studied, I believe that a balanced CPU and memory usage around 70-80% is a good sign, but I need to double-check that.

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.
