Opensearch service CPU load increasing over time

Question

Hi，

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.

How to find the root cause or fix the problem?

Thanks

Best Regards,

Answer

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.
