Low disk usage on content nodes
Elastic Cloud Hosted lets you manage and configure one or more deployments of the versioned Elastic Stack, hosted on Elastic Cloud. Availability This functionality is generally available and ready for production usage. Elastic Cloud on Kubernetes extends Kubernetes orchestration capabilities to allow you to deploy and manage components of the Elastic Stack. Availability This functionality is generally available and ready for production usage. This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes. Elastic Cloud Enterprise is a self-managed orchestration platform for deploying and managing the Elastic Stack at scale. Availability This functionality is generally available and ready for production usage. This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes. Self-managed deployments are Elastic Stack deployments managed without the assistance of an orchestrator.

Content-tier data nodes are using only a small share of provisioned disk over time. You might have oversized content nodes for current index volume and replica layout.
For a complete list of insights, refer to AutoOps insights.
| Field | Value |
|---|---|
| Component | Elasticsearch |
| Severity | Low |
| Scope | Node |
| Domains | disk-storage, resource-utilization |
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 hot 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 hot 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 hot 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.
Content tiers often hold large but relatively stable indices. Persistently low disk use can mean disks or node count exceed what the current layout needs.
If underutilization continues, storage cost remains higher than the current data footprint requires. Keep enough headroom for expected growth before you rightsize.
