How do you emit trace spans from OpenSearch

Hi, Thanks for reaching out to us. Amazon OpenSearch does export its metrics to Cloudwatch, and 3rd party services (like Datadog) can read from Cloudwatch metrics. So you can configure the datadog to read those metrics. You have to check which metrics they are interested in monitoring. Heres the list of available ones: https://docs.aws.amazon.com/opensearch-service/latest/developerguide/managedomains-cloudwatchmetrics.html

Please note that CloudWatch will charge for extra API calls (like metrics reads, dashboards, alarms, etc) so if the 3rd party tool keeps polling CloudWatch API constantly for Opensearch metrics, you will be charged accordingly.

Thank you!

Hi,

Thanks for reaching back. Please note that AWS OpenSearch unfortunately does not have the feature to emit trace data directly. However you can view the latency by the cloudwatch metrics like SearchLatency [1]. This can be visualized using Datadog but not AWS X-ray.

Thank you!
