AWS Grafana connecting to AWS Opensearch `OpenSearch error: Bad Gateway`

Question

We have an AWS Org with AWS Grafana running in the root account setup with Org access.

We have successfully connected to AWS Prometheus and other data sources across different organization accounts. But cant get AWS Grafana to connect to Amazon OpenSearch that is hosted in a VPC.

If you look at Grafana -> AWS Data Sources -> Amazon OpenSearch Service, it lists the cluster. But all attempts to connect have failed.

We have tried setting:

• Using SigV4auth Auth
• Using Basic auth + With Credentials (Even adding VPC connections between accounts and checking ports are open

When we try Save and Test, we always get a Testing.. followed by OpenSearch error: Bad Gateway in grafana.

Has anyone got it working successfully and able to assist?

Answer 1

Been told it’s a known issue.

The solution is to create a proxy for your opensearch cluster and let it get internet access to connect to grafana.

No idea on timelines for AWS to build / fix the problem :(
