Hi
Cloudwatch exporter is configured to poll all the AWS/NetworkELB metrics,
some of the metrics are listed below. Cloudwatch-exporter continuously
logs the error message - CloudWatch scrape failed (see stack trace after
the configurations). Can you suggest what could be wrong here ?
===================== Configuration ====================
region: us-west-2
metrics:
- aws_namespace: AWS/NetworkELB
aws_metric_name: HealthyHostCount
aws_dimensions: [AvailabilityZone, LoadBalancer, TargetGroup]
# set_timestamp: true
- aws_namespace: AWS/NetworkELB
aws_metric_name: UnHealthyHostCount
aws_dimensions: [AvailabilityZone, LoadBalancer, TargetGroup]
# set_timestamp: true
- aws_namespace: AWS/NetworkELB
aws_metric_name: TCP_Target_Reset_Count
aws_dimensions: [AvailabilityZone, LoadBalancer]
===================== End of Configuration ====================
