Low disk usage on warm nodes

Warm-tier data nodes are using only a small share of provisioned disk over time. Extra warm-tier capacity adds cost without improving performance if the data fits on less storage.

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 warm 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.

Warm tiers hold less frequently accessed data. Persistently low disk use often means you can shrink volumes or consolidate nodes after checking retention and growth forecasts.

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