How Robusta KRR calculate replicas in deployments?

[mgfnv9]

Help me please understand, how Robusta calculate metrics and give recommendations if I have two/three pods?

Example

    "object": {
    "cluster": "test-cluster",
    "name": "some-custom-service-deployment",
    "container": "custom-service-gateway",
    "pods": [
      {
        "name": "some-custom-service-deployment-675dc7bd84-zq5dk",
        "deleted": false
      },
      {
        "name": "some-custom-service-deployment-675dc7bd84-slspv",
        "deleted": false
      }
    ],
    "hpa": null,
    "namespace": "some-custom-service",
    "kind": "Deployment",
    "allocations": {
      "requests": {
        "cpu": 0.3,
        "memory": 2147483648.0
      },
      "limits": {
        "cpu": 1.0,
        "memory": 3221225472.0
      },
      "info": {}
    },
    "warnings": []
  },
  "recommended": {
    "requests": {
      "cpu": {
        "value": 0.105,
        "severity": "OK"
      },
      "memory": {
        "value": 2939158528.0,
        "severity": "CRITICAL"
      }
    },
    "limits": {
      "cpu": {
        "value": null,
        "severity": "WARNING"
      },
      "memory": {
        "value": 2939158528.0,
        "severity": "WARNING"
      }
    },
    "info": {
      "cpu": null,
      "memory": null
    }
  },
  "severity": "CRITICAL"
}
 ],
 "score": 15,
 "resources": [
   "cpu",
   "memory"
 ],

in this output recommendations for one pod? or for two all together pods?

Hi @mgfnv9, in the above example, the recommendations were calculated based on 2 pods in that deployment. You would apply the recommendation to the deployment to apply it to each future pod. Does that help?
