AutoOps insights
AutoOps monitors hundreds of metrics on your Elasticsearch deployment and raises an insight when it detects a condition that affects performance, stability, or resource efficiency. Each insight identifies the root cause, explains the impact, and surfaces targeted recommendations so you can act quickly.
Browse insights by category. Each page covers what AutoOps detects and why it matters, insight details (component, severity, scope), customization settings, and an example recommendation.
