Some configurations or settings are not accessible to end users, as OpenSearch Service is a managed service. It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users. Currently, there are strict controls. For instance, if you wish to adjust cluster settings or other parameters, it's challenging for AWS to modify them. The real-time analytics provided by Amazon OpenSearch Service can significantly improve your decision-making processes. Initially, we struggled to determine the correct cluster size and monitor various metrics. You can easily observe metrics like JVM and CPU usage on the monitoring dashboard. This information helps choose the appropriate tool and understand its support and extension capabilities. It would be even better if the service included built-in alerting based on these metrics. If an issue arises, you must manually check the cluster's status. Implementing preconfigured alerts for critical metrics like JVM and CPU usage would significantly enhance the service's usability.
