# Troubleshoot Elasticsearch
This section helps you fix issues with Elasticsearch deployments.
<admonition title="Simplify monitoring with AutoOps" applies-to="{ ess:, ece:, eck:, self:, "serverless": "ga" }">
  AutoOps is a monitoring tool that simplifies cluster management through performance recommendations, resource utilization visibility, and real-time issue detection with resolution paths. Learn more about [AutoOps](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/monitor/autoops).
