We have redone our OpenSearch monitoring setup to rely on the CloudWatch integration instead of using elasticsearch-exporter. This allows us to monitor metrics more reliably and closer to the AWS setup. You will also notice a brand new Grafana dashboard for OpenSearch, which provides a similar view as the AWS-provided CloudWatch dashboard. Additionally we have started upgrading all our AWS OpenSearch domains to 2.19 as versions 2.3 to 2.9 will stop receiving Standard support from AWS on November 7th 2025. While setups used for platform-related features (like Jaeger and Logging) have already been upgraded, we will get in touch with you for upgrading customer-facing domains in the next weeks.
For more information on which features are availbe in OpenSearch 2.19, please refer to the AWS OpenSearch Service pages and the OpenSearch version history documentation . You can also find our updated OpenSearch monitoring runbooks in our public documentation.
