Opensearch service CPU load increasing over time



Our data is very small but we have performance issue on aws opensearch over time.

I monitor /_cat/nodes and I found the CPU load is increasing over time. After trigger blue/green deployment, CPU load is back to low. Enter image description here

How to find the root cause or fix the problem?

You can check the Cloudwatch Metrics of the cluster for indexing & search rates, GC, CPU and Memory metrics and try to co-relate what's happening when the load is increasing. The graphs shared is insufficient to comprehend the underlying cause.

  • I checked Indexing Data Rate, Search rate, JVM memory pressure and Memory utilization but I can't find any co-related items.
