When viewing a Graphite instance in your Grafana Cloud account, the sample configuration for carbon-relay-ng no longer works for the release. The v1.0 release introduces a new
aggregationFile option that is required when using the
grafanaNet output, or else you get this error:
NewGrafanaNetConfig: could not read aggregationFile "": read .: is a directory
The config buried within the Grafana Cloud docs is correct and links to the latest version, so ideally this would be used to update the docs shown when viewing a Graphite instance.
Have also raised Better handling when aggregationFile isn't defined · Issue #469 · grafana/carbon-relay-ng · GitHub around improving the error handling if this new config option isn’t defined.
