How to get cpu utilisation of an ES process

I am using below 2 metrics for CPU usage for a vm and usage of cpu by elastic search process.
But I see the elastic search process CPU utilisation is more than overall CPU usage of the VM.

  1. https://github.com/influxdata/telegraf/tree/master/plugins/inputs/cpu
    usage_user shows me the total cpu usage for a vm.
  2. https://github.com/influxdata/telegraf/tree/master/plugins/inputs/elasticsearch
    elasticsearch_process cpu_percent
    Could you please tell me if I am using the right params.

Ideally elastic search process cpu should be lower than the total cpu utilization of the vm .

Please let me know if there is any other tag which i need to use to get the correct es process cpu utilisation metrics.
