Hi Team,  
We need to find the CPU and Memory utilization % of pods in kubernetes through metricbeat.  
I have used the formula as:  
CPU:

> {  
> "aggs": {  
> "timeseries": {  
> "auto\_date\_histogram": {"field": "@timestamp", "buckets": "1"},  
> "aggs": {  
> "hosts": {  
> "terms": {"field": "kubernetes.pod.name.keyword", "size": 1000},  
> "aggs": {  
> "usage": {"avg": {"field": "kubernetes.container.cpu.usage.nanocores"}},  
> "transform": {  
> "bucket\_script": {  
> "buckets\_path": {"nano": "usage"},  
> "script": {  
> "source": "Math.round((params.nano/1000000000)\*100)",  
> "lang": "painless"  
> }  
> }  
> }

Memory:

> {  
> "aggs": {  
> "timeseries": {  
> "auto\_date\_histogram": {"field": "@timestamp", "buckets": "1"},  
> "aggs": {  
> "hosts": {  
> "terms": {"field": "kubernetes.pod.name.keyword", "size": 100},  
> "aggs": {  
> "usage": {"avg": {"field": "kubernetes.container.memory.usage.bytes"}},  
> "total": {  
> "avg": {  
> "field": "kubernetes.container.memory.limit.bytes"  
> }  
> },  
> "transform": {  
> "bucket\_script": {  
> "buckets\_path": {"nano": "usage", "core": "total"},  
> "script": {  
> "source": "Math.round((params.nano/params.core)\*100)",  
> "lang": "painless"  
> }  
> }  
> }

If we use the below fields then there is a huge difference in the values:

| **CPU Usage** | Average of `kubernetes.pod.cpu.usage.node.pct`. |
| --- | --- |
| **Memory Usage** | Average of `kubernetes.pod.memory.usage.node.pct`. |

I would like to understand that which fields are correct for getting utilization in %.

Please support.

Hi Team,  
Can someone suggest?
