EC2 Dashboard stopped working.

[sunny5055]

EC2 dashboard was working ( using IAM user ) Suddenly stopped working

Mainly its not able to pull out the tags which the dashboard template has.

Object { error: "metric request error: "InvalidParameter: 1 validation error(s) found.\n- minimum field size of 1, GetMetricDataInput.MetricDataQueries[0].MetricStat.Metric.Dimensions[0].Value.\n"" }

unexpected error failed to call ec2:DescribeInstances, MissingParameter: The request must contain the parameter InstanceId
status code: 400, request id: 86e0c6de-375a-4d2f-b2b6-7c744392c946null

Anyone else have the same issue?

Further digging looks like this issue is purely related to filter for Instance Name and Instance ID.

I have the exact same issue, looks like something is wrong with filter {"tag:Name": ["$instancename"]}.

Could you try to create dashboard from the scratch, please? I have seen that sometimes migration to new dashboard model doesn't work very well (Grafana 8.x). I will be helpfull also if you report your Grafana version.

There was no migration done. It suddenly stopped working with existing version.
I have tried to create freshly create a new dashboard with import numerous times, it still has the same issue.
Grafana v8.5.1

Could you enable Grafana debug logs and provide Grafana logs, pls?

I have updated Grafana from 8.5.0 to 8.5.1 and suddenly it started working. Apparently it was a known issue
https://github.com/grafana/grafana/releases/tag/v8.5.1
