Low disk usage on cold nodes
Cold-tier data nodes are using only a small share of provisioned disk over time. Paid storage sits idle while monthly disk charges continue.

The following is an example of what you might see when this insight is triggered. Real insights use live data and links from your deployment or cluster.
Disk utilization is low on the cold tier nodes: es-data-01 and es-data-02.
These nodes are using only 85% of available disk space.
AutoOps shows different recommendations depending on how their conditions match your deployment or cluster.
Reduce disk size on data nodes
Condition: Always shown for this insight.
Disk usage on cold nodes is below 48 GB%. Switch to smaller disks to improve utilization while keeping enough headroom for growth.
Reduce data node count
Condition: Always shown for this insight.
Disk usage on cold nodes is below 48 GB%. Scale down the tier if remaining capacity still meets your headroom target.
When provisioned disk stays underused for a sustained period, you pay for storage capacity the cluster is not using.
Cold tiers are cost-sensitive. Sustained low utilization usually means volumes or node count exceed what ILM retention and growth require.
If underutilization continues, storage cost remains higher than the current data footprint requires. Keep enough headroom for expected growth before you rightsize.
