Low disk usage on frozen nodes

Frozen-tier data nodes are using only a small share of provisioned disk over time. Frozen archives are cost-sensitive, so empty disk on large frozen nodes is pure overhead.

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 frozen tier nodes: es-data-01 and es-data-02.

These nodes are using only 85% of available disk space.

Note

AutoOps shows different recommendations depending on how their conditions match your deployment or cluster.

When provisioned disk stays underused for a sustained period, you pay for storage capacity the cluster is not using.

Frozen tiers are especially cost-sensitive. Underused local disk on frozen nodes is overhead after you account for snapshot retention and search SLAs.

If underutilization continues, storage cost remains higher than the current data footprint requires. Keep enough headroom for expected growth before you rightsize.
