Hello,
I am benchmarking Aerospike and I have notices some weirdness with the reporting. I am using snmp to gather metrics and I see the CPU at around 4% (96% idle), which is way lower than I would expect considering that I have a large client simulating load on another machine.
05:59:50 PM CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle
05:59:50 PM all 0.48 0.00 0.55 0.01 0.00 0.67 2.03 0.00 0.00 96.26
When I look at top I see the weirdness…
The CPU matches with the 3-4% almost totally Idle, but the processes list shows:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
2326 root 20 0 6965640 2.001g 2940 S 500.0 6.9 155:12.33 asd
I see the process is using 500.0% which for this 16 core machine would be about 34% total.
As it is a virtual machine, I see the total CPU usage of the VM is about 38%, which I would expect. Any ideas why Aerospike is misreporting it’s usage so wildly?
For another veiw,
mpstat shows less than 4% CPU utilization

540% cpu with ps …

Any ideas?
Is there a way to get the snmp data to show the actual usage of Aerospike?
