## Example: What you might see in AutoOps

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.

### No statistics were received for the cluster


#### What was detected

No metrics received for: node_stats, cluster_stats

#### Recommendations

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

<dropdown title="Check ingest client configuration">
  **Condition**: Always shown for this insight.Verify the Beats, Elastic Agent, Logstash, or other clients shipping data to this cluster: confirm the process is running, connected to the cluster, and not reporting errors in its logs. Review index names, pipelines, and throughput settings match what you expect for this index pattern.
</dropdown>


#### Background and impact

Impact: AutoOps couldn't connect to your cluster and therefore is cannot monitor and operate the cluster at the moment.
