[jira] [Commented] (SOLR-12208) Don't use "INDEX.sizeInBytes" as a tag name in policy calculations

    [ https://issues.apache.org/jira/browse/SOLR-12208?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16606227#comment-16606227 ] 

Cassandra Targett commented on SOLR-12208:
------------------------------------------

[~ab], [~noble.paul]: The Ref Guide still references {{INDEX.sizeInBytes}} in 3 places in 2 files: 2x in {{metrics-history.adoc}} and 1x in {{solrcloud-autoscaling-triggers.adoc}}. 

ALL of these references need to be changed to {{INDEX.sizeInGB}}, correct?

> CORE_IDX and FREEDISK ConditionType reuse this metric name, but they assume the values are expressed in gigabytes. This alone is confusing considering the name of the metric.
> Additionally, it causes conflicts in the simulation framework that would require substantial changes to resolve (ReplicaInfo-s in SimClusterStateProvider keep metric values in their variables, expressed in original units - but then the Policy assumes it can put the values expressed in GB under the same key... hilarity ensues).
