Autoscaling question

[Kudrettin Güleryüz <ku...@gmail.com>]

Hi,

I'd like to balance freedisk and cores across eight nodes. Here is my
cluster-preferences and cluster-policy:

{
  "responseHeader":{
    "status":0,
    "QTime":0},
  "cluster-preferences":[{
      "precision":10,
      "maximize":"freedisk"}
    ,{
      "minimize":"cores",
      "precision":10}
    ,{
      "minimize":"sysLoadAvg",
      "precision":3}],
  "cluster-policy":[{
      "freedisk":"<10",
      "replica":"0",
      "strict":"true"}],
  "triggers":{".auto_add_replicas":{
      "name":".auto_add_replicas",
      "event":"nodeLost",
      "waitFor":120,
      "actions":[{
          "name":"auto_add_replicas_plan",
          "class":"solr.AutoAddReplicasPlanAction"},
        {
          "name":"execute_plan",
          "class":"solr.ExecutePlanAction"}],
      "enabled":true}},
  "listeners":{".auto_add_replicas.system":{
      "trigger":".auto_add_replicas",
      "afterAction":[],
      "stage":["STARTED",
        "ABORTED",
        "SUCCEEDED",
        "FAILED",
        "BEFORE_ACTION",
        "AFTER_ACTION",
        "IGNORED"],
      "class":"org.apache.solr.cloud.autoscaling.SystemLogListener",
      "beforeAction":[]}},
  "properties":{},
  "WARNING":"This response format is experimental.  It is likely to
change in the future."}

Can you help me understand why least loaded node is test-54 in this case?
{
  "responseHeader":{
    "status":0,
    "QTime":1294},
  "diagnostics":{

      {

        "cores":99,
        "freedisk":1045.345874786377,
        "sysLoadAvg":6.0},
      {
        "node":"test-51:8983_solr",
        "cores":94,
        "freedisk":1029.996826171875,
        "sysLoadAvg":17.0},
      {
        "node":"test-55:8983_solr",
        "cores":98,

      {
        "node":"test-54:8983_solr",
        "cores":165,
        "freedisk":580.5822525024414,
        "sysLoadAvg":0.0}],
    "violations":[]},
  "WARNING":"This response format is experimental.  It is likely to

Solr 7.3.1 is running.

Thank you
