Metrics are not sending to specific region

[jtran0721]

Hi, I would like some help with sending metrics to different region rather than us-east-1. I ran this command

docker run -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN -e AWS_DEFAULT_REGION="ap-southeast-1" --rm bk-agent-metrics -token $token -interval 30s -queue mac:build -backend cloudwatch -cloudwatch-region "ap-southeast-1”

I couldn't see metrics in "ap-southeast-1" but they exist in "us-east-1". Do you know why is this happening?

Thank you

Hi @jtran0721, I think you found a bug!

buildkite-agent-metrics/main.go

Lines 75 to 81 in 7ffd290

	case "cloudwatch":
	region := *clwRegion
	if envRegion := os.Getenv(`AWS_REGION`); region == "" && envRegion != "" {
	region = envRegion
	} else {
	region = `us-east-1`
	}

Since you're passing -cloudwatch-region, region != "", so the code ends up in the else, which overrides it with us-east-1. That's pretty clearly wrong, and has been since that code was added!
