Query data error while we are building this sample #71

Closed cpalanisamy closed 2 years ago

cpalanisamy commented 2 years ago

Hi Team, We had set up the CookieFactory sample to explore the Twinmaker. Since yesterday, we have started to see Query Data error on the Alarms List panel on the CookieFactory AWS Managed Grafana Dashboard. We have tried multiple ways to debug this issue and we need the experts to support us here. Error

Can someone help us on this issue to proceed further?

Update: When we tried with a local instance of grafana. We see the below error in the log. 

logger=context traceID=00000000000000000000000000000000 userId=1 orgId=1 uname=admin t=2022-06-17T09:30:52.699790656Z level=error msg="Query data error" error="failed to query data: Failed to query data: rpc error: code = Unavailable desc = error reading from server: EOF" remote_addr=103.210.207.111 traceID=00000000000000000000000000000000

Hi Palani, we have identified a fix for this issue. We plan to have the deployment done by early 6/22. Will update the thread once it finishes. Which AWS region do you mainly use for testing?

Thanks.

Hi Steve, Thanks for the response. I am using US-EAST-1 as the default region.

Thanks, Palani

stevenyang-aws commented 2 years ago

Could you verify if the issue is resolved in us-east-1? Thank you!

Hi Steve, I can confirm that the issue is fixed in us-east-1. Just to be curious, may I know the cause for this issue?

Thanks & Regards, Palani

Hi Palani, this is due to some unexpected change in our service, which caused the errors in Grafana. We are internally coming up with action items to prevent such issue in the future.

Thanks for trying out the samples and exploring TwinMaker. I am closing this issue. Please feel free to re-open if you have other questions. Thanks!
