Context

CSS monitors various metrics of the running status and change trend of cluster indexes to measure service usage and handle potential risks in a timely manner, ensuring that clusters can run stably.

During index monitoring, the stats information about indexes is collected and saved to the monitoring index (monitoring-eye-css-[yyyy-mm-dd]) of the cluster, and retained for one week by default.

Currently, only clusters of the version 7.6.2 support index monitoring.
